3.2.1.2.3 Test Gain
‘Test Gain’ performs a test of the system electronics to determine if
the gain setting is optimal. Test results inform the user if the gain is
correct, or, if there is too much or too little gain; however, it does not
reset the gain. Resetting gain must be done using the ‘Autoset Gain’
or ‘Check / Set Gain’ commands. ‘Test Gain’ should be run while the
process is operating at normal conditions to avoid getting an incorrect
gain value.
