Standby - Teledyne 4040 Instruction, Operating And Maintenance Manual

Operation
Use the same procedure to set the gain of the instrument. After the
last digit is entered, the final <Enter> press will accept the gain value.
The values entered do not have explicit units of current or voltage.
Adjustment should be gauged using a voltmeter or current meter
attached to the analog output. When the ANALOG ADJUST menu is
entered the following is displayed:
________________________________________________
-> CH1 mA Offset:
CH1 mA Gain:
________________________________________________
When the arrow is on the Offset, or when the user presses <Enter> to
modify the offset, the analog output is 4mA plus a value that is
proportionate to the number indicated to the right of 'Offset:' That
number may be modified –500 to 500.
When the arrow is on the Gain, or when the user presses <Enter> to
modify the gain, the output is 20mA scaled by the value to the right of
'Gain: ' plus the Offset value.
If these 2 values are modified and entered and accepted, then the
analog output will be affected in like manner in ANALYSIS MODE.
That is, it will be scaled byte the gain value, then summed with the
offset value.
The analog output for each channel may be set to source CH4,
NMH, THC, or WAVE. In the case of CH4/HMH/THC, the output will
reflect the percent of range for the respective selection. In the case of
WAVE, the output will track the FID output.
