Bacharach AGM300 - Manual (Page 47)

Instruction 3015-4275 39
Loop 2 Factor
This sets the PPM scale factor for current loop number 2. To calculate the current output, multiply the scale factor
by the PPM and add 4. For example, at the default scale factor of 0.016, a measurement of 100 PPM would
generate a current of 5.6 mA. In no case can current output exceed the 20 mA capacity of the interface.
1. Press the LOOP2 FACTOR key to adjust the setting.
2. Use the LEFT/RIGHT cursor keys to move across the entry field and the UP/DOWN cursor keys to
modify the individual numbers.
3. Press ENTER to accept the new entry or QUIT to revert to the previous setting.
Re-Zero Mode
This parameter defines the frequency at which the instrument re-zeros the optical sensor.
1. Press the REZERO MODE key to adjust the setting.
2. Use the UP/DOWN cursor keys to toggle between settings.
AUTO – Sets the instrument to re-zero every 10 minutes.
ZONE CHANGE – Sets the instrument to re-zero at each zone change. This is the most accurate
setting but increases the time interval between measurement cycles.
3. Press ENTER to accept the new entry or QUIT to revert to the previous setting.
