ITEST Testing the analog outputs

The operation of the analog outputs are tested by forcing the outputs

to given values. The values in the analog outputs can then be

measured with a current/voltage meter.

ITEST aa.aaa bb.bbb ↵

where: aa.aaa = current value to be set for channel 1

bb.bbb = current value to be set for channel 2
