Changing the 4-20 mA
Analog Output Range
The XMO2 Calibration Sheet shipped with the unit lists the 4-20 mA
analog output range that was set at the factory. To change this range
using RS232 digital communication, perform the following steps:
1. If the XMO2 is not set up for Easy Menu Entry, enter the XMO2
Basic Menu by slowly keying in
[Shift]+[1] or [Enter], [1], [2], [3].
Refer to the menu map in Figure C-1 on page C-1 for the options
available in this menu.
2. Press
[N] repeatedly until the following display appears:
Note: The low input value is the %O
2
in the sample gas that will
generate an analog output current of 4.00 mA.
3. At the above screen, do one of the following:
• Press [Y] or [Enter] to accept the current low input value (0.00 in
the above example). Then, go to Step 5.
• Use the numeric keys to enter a new low input value (5.00 in
the example that follows). Then, go to Step 4.
4. If you entered a new low input value:
5. Continue the procedure as follows:
Note: The high input value is the %O
2
in the sample gas that will
generate an analog output current of 20.00 mA.
