Instrument Errors
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.
307 Incorrectly 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.
308 Channel not able to perform requested operation
The channel is unable to perform the requested operation.
309 Incorrectly formatted channel list
The channel list is not formatted correctly. Examples of proper formats
are shown below.
(@321) - channel 21 on the module in slot 300.
(@221:222) - channels 21 through 22 on the module in slot 200.
(@121:122,222,321:322) - channels 21 and 22 on the module in slot 100,
channel 22 on the module in slot 200, and channels 21-22 on the module
in slot 300.
