Instrument Errors

303

Module not able to perform requested operation

 

A command was received which is not valid for the specified module.

 

This error is most commonly generated when you send a command

 

intended for the multifunction module to a switching module.

305

Not able to perform requested operation

 

The requested operation is not valid for the specified channel. You may

 

have tried to a configure a channel for current measurements (valid only

 

on channels 21 and 22 on the 34901A module). Or you may have tried to

 

configure scaling on a module that does not connect to the internal

 

DMM.

306

Part of a 4-wire pair

 

For 4-wire resistance measurements, the instrument automatically

 

pairs channel n with channel n+10 (34901A) or n+8 (34902A) to provide

 

the source and sense connections. To change the configuration on the

 

upper channel in a 4-wire pair, you must first reconfigure the lower channel

 

to a measurement function other than 4-wire resistance.

307Incorrectly configured ref channel

For thermocouple measurements using an external reference, the instrument automatically reserves channel 01 on the multiplexer in the lowest slot as the reference channel. Before configuring a thermocouple channel with an external reference, you must configure the reference channel (channel 01) for a thermistor or RTD measurement.

This error is also generated if you change the function on the reference channel (channel 01) after selecting the external reference source on a thermocouple channel.
