After the calibration has been conducted, a CAL FACTOR will be
calculated; this determines the calibration of the instrument. The cal
factor will be displayed for a few seconds after a calibration has been
conducted, and it can also be interrogated from Mode 4 (diagnostic
mode). Enter the cal factor into the table below, as a record of
instrument operation.

This is set at the factory and should not be altered without due consideration.
The current output should now be set up using a calibrated milliammeter set
to DC current, 20 mA max. Conduct this procedure as follows :
1. Connect the milliammeter to the output terminals within the signal
processor - terminals +mA and -mA.
2. Enter the SET UP MODE - CONFIGURE OUTPUT - SET ZERO
OPTION, and adjust the level using the ARROW keys until 0mA is
recorded. Record the value in brackets on the display in Table 2 -
