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. 

Table 3-2.  Calibration Data

Factory settings were obtained under the following conditions: 

• 6.5 ft (2 m) path length 
• Clean conditions 
• 240V, 50 Hz supply 

NOTE
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 - 
Calibration Data. 

3. Enter the SETSPAN option and adjust the level using the ARROW keys 

until 20 mA is recorded. Record the value in brackets on the display in 
Table 2 - Calibration Data.
