Win32_VoltageProbe

The Win32_VoltageProbe WMI class represents the properties of a voltage sensor (electronic voltmeter).

The Win32_VoltageProbe WMI class represents the properties of a voltage sensor (electronic voltmeter).

Methods

Win32_VoltageProbe has no methods. Inherited methods (Reset and SetPowerState) are not implemented.

Properties

Win32_VoltageProbe returns 35 properties:

'Accuracy','Availability','Caption','ConfigManagerErrorCode',
'ConfigManagerUserConfig','CreationClassName','CurrentReading','Description','DeviceID','ErrorCleared',
'ErrorDescription','InstallDate','IsLinear','LastErrorCode','LowerThresholdCritical',
'LowerThresholdFatal','LowerThresholdNonCritical','MaxReadable','MinReadable','Name','NominalReading',
'NormalMax','NormalMin','PNPDeviceID','PowerManagementCapabilities','PowerManagementSupported',
'Resolution','Status','StatusInfo','SystemCreationClassName','SystemName','Tolerance',
'UpperThresholdCritical','UpperThresholdFatal','UpperThresholdNonCritical'

Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:

Get-CimInstance -ClassName Win32_VoltageProbe -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_VoltageProbe exist. This is normal behavior.

Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).

Accuracy

SINT32

Accuracy of the sensor for the measured property. The accuracy value is recorded as plus or minus hundredths of a percent. Accuracy, along with resolution and tolerance, is used to calculate the actual value of the measured physical property. The accuracy may vary and depends on whether or not the device is linear in its dynamic range.

Get-CimInstance -ClassName Win32_VoltageProbe | Select-Object -Property DeviceID, Accuracy

Availability

UINT16

Availability and status of the device.

Availability returns a numeric value. To translate it into a meaningful text, use any of the following approaches:

Use a PowerShell Hashtable
$Availability_map = @{
      1 = 'Other'
      2 = 'Unknown'
      3 = 'Running/Full Power'
      4 = 'Warning'
      5 = 'In Test'
      6 = 'Not Applicable'
      7 = 'Power Off'
      8 = 'Off Line'
      9 = 'Off Duty'
     10 = 'Degraded'
     11 = 'Not Installed'
     12 = 'Install Error'
     13 = 'Power Save - Unknown'
     14 = 'Power Save - Low Power Mode'
     15 = 'Power Save - Standby'
     16 = 'Power Cycle'
     17 = 'Power Save - Warning'
     18 = 'Paused'
     19 = 'Not Ready'
     20 = 'Not Configured'
     21 = 'Quiesced'
}
Use a switch statement
switch([int]$value)
{
  1          {'Other'}
  2          {'Unknown'}
  3          {'Running/Full Power'}

     21 = 'Quiesced'
}

#endregion define hashtable

#region define calculated property (to be used with Select-Object)

<#
  a calculated property is defined by a hashtable with keys "Name" and "Expression"
  "Name" defines the name of the property (in this example, it is "Availability", but you can rename it to anything else)
  "Expression" defines a scriptblock that calculates the content of this property
  in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
  value to its friendly text counterpart:
#>
 
$Availability = @{
  Name = 'Availability'
  Expression = {
    # property is an array, so process all values
    $value = $_.Availability
    $Availability_map[[int]$value]
  }  
}
#endregion define calculated property

# retrieve the instances, and output the properties "Caption" and "Availability". The latter
# is defined by the hashtable in $Availability: 
Get-CimInstance -Class Win32_VoltageProbe | Select-Object -Property Caption, $Availability

# ...or dump content of property Availability:
$friendlyValues = Get-CimInstance -Class Win32_VoltageProbe | 
    Select-Object -Property $Availability |
    Select-Object -ExpandProperty Availability

# output values
$friendlyValues

# output values as comma separated list
$friendlyValues -join ', '

# output values as bullet list
$friendlyValues | ForEach-Object { "- $_" }
Use $Availability_map to directly translate raw values from an instance
<# 
  this example uses a hashtable to manually translate raw numeric values 
  for property "Win32_VoltageProbe" to friendly text. This approach is ideal when
  there is just one instance to work with.

  Note: to use other properties than "Win32_VoltageProbe", look up the appropriate 
  translation hashtable for the property you would like to use instead.

# translate raw value to friendly text:

Use a switch statement inside a calculated property for Select-Object
<# 
  this example uses a switch clause to translate raw numeric 
  values for property "Availability" to friendly text. The switch
  clause is embedded into a calculated property so there is
  no need to refer to external variables for translation.

  Note: to use other properties than "Availability", look up the appropriate 
  translation switch clause for the property you would like to use instead.

  6          {'Power Cycling Supported'}
  7          {'Timed Power On Supported'}
  default    {"$value"}
}
Use Enum structure
Enum EnumPowerManagementCapabilities
{
  Unknown                                    = 0
  Not_Supported                              = 1

Enums must cover all possible values. If PowerManagementCapabilities returns a value that is not defined in the enum, an exception occurs. The exception reports the value that was missing in the enum. To fix, add the missing value to the enum.

PowerManagementSupported

BOOLEAN

If TRUE, the device can be power-managed, which means that it can be put into suspend mode, and so on. The property does not indicate that power management features are currently enabled, but it does indicate that the logical device is capable of power management.

Get-CimInstance -ClassName Win32_VoltageProbe | Select-Object -Property DeviceID, PowerManagementSupported

Resolution

UINT32 “TENTHS OF MILLIVOLTS”

Ability of the sensor to resolve differences in the measured property. This value may vary and depends on whether the device is linear in its dynamic range.

Get-CimInstance -ClassName Win32_VoltageProbe | Select-Object -Property DeviceID, Resolution

Status

STRING MAX 10 CHAR

Current status of an object. Various operational and nonoperational statuses can be defined. Available values:

$values = 'Degraded','Error','Lost Comm','No Contact','NonRecover','OK','Pred Fail','Service','Starting','Stopping','Stressed','Unknown'
Get-CimInstance -ClassName Win32_VoltageProbe | Select-Object -Property DeviceID, Status

StatusInfo

UINT16

State of the logical device. If this property does not apply to the logical device, the value 5 (Not Applicable) should be used.

StatusInfo returns a numeric value. To translate it into a meaningful text, use any of the following approaches:

Use a PowerShell Hashtable
$StatusInfo_map = @{
      1 = 'Other'
      2 = 'Unknown'
      3 = 'Enabled'
      4 = 'Disabled'
      5 = 'Not Applicable'
}
Use a switch statement
switch([int]$value)
{
  1          {'Other'}
  2          {'Unknown'}
  3          {'Enabled'}
  4          {'Disabled'}
  5          {'Not Applicable'}
  default    {"$value"}
}
Use Enum structure
Enum EnumStatusInfo
{
  Other            = 1
  Unknown          = 2
  Enabled          = 3
  Disabled         = 4
  Not_Applicable   = 5

UpperThresholdCritical

SINT32 “MILLIVOLTS”

Sensor threshold values specify the ranges (minimum and maximum values) to determine whether the sensor is operating under normal, noncritical, critical, or fatal conditions. If CurrentReading is between UpperThresholdCritical and UpperThresholdFatal, the current state is critical.

Get-CimInstance -ClassName Win32_VoltageProbe | Select-Object -Property DeviceID, UpperThresholdCritical

UpperThresholdFatal

SINT32 “MILLIVOLTS”

Get-CimInstance -ClassName Win32_VoltageProbe | Select-Object -Property DeviceID, UpperThresholdFatal

UpperThresholdNonCritical

SINT32 “MILLIVOLTS”

Sensor threshold values specify the ranges (minimum and maximum values) to determine whether the sensor is operating under normal, noncritical, critical, or fatal conditions. If CurrentReading is between LowerThresholdNonCriticaland UpperThresholdNonCritical, the sensor is reporting a normal value. If CurrentReading is between UpperThresholdNonCritical and UpperThresholdCritical, the current state is noncritical.

Selecting Properties

To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.

Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.

Selecting Properties

The code below lists all available properties. Remove the ones you do not need:

$properties = 'Accuracy',
              'Availability',
              'Caption',
              'ConfigManagerErrorCode',
              'ConfigManagerUserConfig',
              'CreationClassName',
              'CurrentReading',

Limiting Network Bandwidth

If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:

Get-CimInstance -Class Win32_VoltageProbe -Property $property | 
Select-Object -Property $property

Selecting Instances

To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).

The parameter -Filter runs a simple query.

Listing all instances where the property Caption starts with “A”
Get-CimInstance -Class Win32_VoltageProbe -Filter 'Caption LIKE "a%"' 
Using a WQL Query

The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:

Get-CimInstance -Query "SELECT UpperThresholdNonCritical, NormalMin, StatusInfo, LowerThresholdNonCritical FROM Win32_VoltageProbe WHERE Caption LIKE 'a%'"

Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:

Get-CimInstance -Query "SELECT UpperThresholdNonCritical, NormalMin, StatusInfo, LowerThresholdNonCritical FROM Win32_VoltageProbe WHERE Caption LIKE 'a%'" | Select-Object -Property UpperThresholdNonCritical, NormalMin, StatusInfo, LowerThresholdNonCritical

Accessing Remote Computers

To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.

Authenticating as Current User
# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_VoltageProbe -ComputerName $list 
$result
Authenticating as Different User

Use a CIMSession object to authenticate with a new identity:

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred

$result = Get-CimInstance Win32_VoltageProbe -CimSession $session

# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session

$result

Requirements

To use Win32_VoltageProbe, the following requirements apply:

PowerShell

Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.

If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.

Operating System

Win32_VoltageProbe was introduced on clients with Windows Vista and on servers with Windows Server 2008.

Namespace

Win32_VoltageProbe lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.

Implementation

Win32_VoltageProbe is implemented in CIMWin32.dll and defined in CIMWin32.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\CIMWin32.mof
