Operating the Analyzer
Operator’s Manual 2
–7
Returning to Mode 1 re-establishes normal 4-20 mA current loop operation.
Mode 6: (Diagnostic Data download)
Mode 6 is used to transfer diagnostic data to the serial port and read the
individual data points of both the DC and 2f spectra that the instrument
analyzes to calculate the gas concentration. Viewing these data can be helpful
in diagnosing problems with the analyzer. Press the # key followed by the 6
key.
The data points, along with intermediate calculation results, are output to the
serial port whenever Mode 6 is selected.
Mode 7: (Measure Port1 Mode)
Mode 7 switches the analyzer to measure validation gas supply #1. Press the
# key followed by the 7 key.
Returning to Mode 1 re-establishes normal operation measuring process gas.
