VM
This command defines channels that are used as voltmeters.
Usage
VM

Voltmeter channel: 1 to 9; the assigned value for a voltmeter depends on how
instruments are mapped in KCon

User-specified name (up to 6 characters)
Details
KXCI allows up to eight source-measure units (SMUs) to function solely as voltmeters. You can use
any channel for any voltmeter function between VM1 and VM9. For example, in a system containing
four SMUs, you can use
SMU3
as
VM7
.
If you do not define one of the 4200A-SCS SMUs to emulate a VM, attempts to measure voltages
through the nonexistent VM result in data values of
9.000e+37
.
If nothing is specified after the prefix and channel number, the channel is not used.
To measure voltage using the 4145B
VM1...VM
n
function, define one of the 4200A-SCS SMUs to
emulate
VM
.
Example
VM1, 'VM1'
This command string defines the channel used for VM1 (specifies the name
VM1
).
