5.4 mA Output Setup
The mA output menu allows the user to configure the measurand, zero and span information for the attached
mA boards. In addition, the menu allows the user to simulate a given value on any attached board to test each
individual channel.

measurands (device dependant):
• CO
• NO
• NO2
By pressing the key, the user can enter the configuration sub menu
Using the or keys, the menu will cycle through the available measurands. Pressing the sets the
currently selected species.
NOTE: If the measurand is not listed in the selection list the device will display “N/A” and treat the
species with all default settings.
5.4.2 mA Zero Value
When setting the Zero value on the mA card, the menu system uses the measurand to determine how to handle
the requested information.
Example:
CO, NO, NO2 and the N/A measurands are all retrieved and set to 1 decimal place whereas VIS percent is set to
2 decimal places and VIS K to 4 decimal places.
To ensure the user is on the correct menu, the menu also displays the current measurand to be altered.
By pressing the key, the user can adjust the current value for the selected mA channel.
