Calibrating Analog Output

The analog output can be calibrated to correct for any variances caused by the users input equipment.
The calibration routine allows the user to adjust the 4mA and 20mA output values.
The calibration routine is entered from the STATUS screen. NOTE: When entering the calibration
routine, any incoming frequency to the MX 9000 is ignored. Before starting the calibration routine,
make sure the analog output is connected to the intended readout equipment. To calibrate the MX
9000 it is necessary to enter the analog value read from the user’s readout equipment.
