Reading relay closure count

To determine the closure count of specific channels, send this query via remote:

:ROUTe:CLOSe:COUNt? (@clist)

Here, clist is the summary of channels. For example, to determine the closure count of

channels 1 and 4 of a module in slot 1, the following query would be sent:

:ROUT:CLOS:COUN? (@101,104)

The following query would determine the closure count of slot 1 module channels 1

:ROUT:CLOS:COUN? (@101:110)

To reset the relay closure count of specific channels to 0, send this command via remote:

:ROUTe:CLOSe:RCOunt (@clist)

Again clist is the summary of channels to be reset. For example, the following command

resets channels 2 and 7 of a module in slot 1 to 0:

:ROUT:CLOS:RCO (@102,107)

The following command resets the count of slot 1 module channels 1 through 10:

:ROUT:CLOS:RCO (@101:110)

Model 2790 SourceMeter

The Model 2790 must be in the manufacturing calibration mode to reset the

closure count. To do so, press and hold the OPEN key while turning on the

power, then send the :CAL:PROT:CODE "code" to unlock calibration (default

code: KI002790). After resetting relay counts, send :CAL:PROT:LOCK to lock

out calibration.
