Analog Input Calibration

3-84 Model 42i Instruction Manual
ANALOG OUTPUT CAL:
>CALIBRATE ZERO
The Analog Output Calibrate Zero screen allows the user to calibrate the
zero state of the selected analog output. The operator must connect a volt
Zero
meter to the output and adjust the output until it reads 0.0 V on the meter
for a voltage channel, or either 0 or 4 mA for a current channel (depending
on the selected range). See the "set output to:" field on the display.
In the Main Menu, choose Service > Analog Out Cal > select Channel
●
> Calibrate Zero.
ANALOG OUTPUT CAL:
The Analog Output Calibrate Full-Scale screen allows the user to calibrate
the full-scale state of the selected analog output. The operator must connect
Full-Scale
a volt meter to the output and adjust the output until the meter reads the
value shown in the "set output to:" field, in either V or mA, depending on
the selected output channel.
In the Main Menu, choose Service > Analog Out Cal > select Channel
●
> Calibrate Full Scale.
ANALOG OUTPUT CAL:
The Analog Input Calibration menu is used to calibrate the 8 analog input
channels at both zero and full-scale. The Analog Input Calibration menu is
