Additionally A1, A2 and A3 may be equipped with optional 0-20 mA current loop

drivers. The 4-20 mA option is not available on A4.

Note: In actuality the analog output configuration of the analyzer may be different

than stated above. The outputs can be configured differently at the factory

depending on whether they were assigned during the procurement of the product.

It is possible to check the configuration of the analyzer by accessing the ANALOG

I/O CONFIGURATION through the DIAG menu.

The analyzer operates in Dual Mode during gas detection. This means each of the

measured concentrations can have two separate slopes and offsets, one for the

low range and one for the high range. Though uncommon, a user may decide to

calibrate the analyzer with nitric oxide at, for example, 100 PPB using the LOW

range and then perform another calibration at 450 PPB using the HIGH range.

Through the analog outputs the user can then assign analog output A1 to

CNC1 and output A2 to TNxCNC2. Gases with the “1” designation use the

slope and offset for the LOW range, while gases with the “2” designation will use

the slope and offset for the HIGH range

It is recommended that both the LOW and

HIGH ranges be calibrated at the same time. Independent of whether the HIGH

range is actually being outputted to the analog outputs.
