INPut:IMPedance:AUTO
Syntax
INPut:IMPedance:AUTO <state>[,(@<ch_list>)]
INPut:IMPedance:AUTO? [(@<ch_list>)]
Description
This command enables or disables the automatic input resistance mode for DC voltage measurements on the specified channels.
Parameters
Name Type Range of Values Default Value <state> Boolean {OFF|0|ON|1} This is a required parameter. <ch_list> Channel List One or more channels, as shown:
(@310) - channel 10 on the module in slot 300.
(@305:310) - channels 05 through 10 on the module in slot 300.
(@202:207,209,302:308) - channels 02 through 07 and 09 on the module in slot 200 and channels 02 through 08 on the module in slot 300.
If you omit the optional <ch_list> parameter, this command applies to the currently defined scan list.
Remarks
- With AUTO OFF (default), the input resistance is fixed at 10 MΩ for all ranges.
- With AUTO ON, the input resistance is set to >10 GΩ for the 100 mV, 1 V, and 10 V ranges.
Return Format
The query returns the input resistance setting as 0 (OFF) or 1 (ON) on the specified channels.
Examples
The following command sets the impedance to >10 GΩ for two channels.
INP:IMP:AUTO ON (@105,109)
The following queries for the impedance on two channels.
INP:IMP:AUTO? (@105,109)
Typical Response: 1,1
