5200 Multi Purpose and 5200 Multi Purpose HF Gas Analysers

6.6 Configuring and using the milliAmp outputs (optional feature)
6.6.1 Overview
The Multi Purpose can be supplied with a milliAmp output for each sample gas
measurement for which the Multi Purpose is configured. Each milliAmp output
provides a constantly updated output (from the connector(s) on the rear of the Multi
Purpose, see Figure 2), in which the current represents the value of gas sample
measurements.
The Multi Purpose allows you to specify two separate output configurations for each
milliAmp output: Range 1 and Range 2. The Range with which a measurement is
currently associated is shown on the Measurement screen (see Figure 3):
Each milliAmp output provides one of the following selectable output current ranges,
for gas sample measurements:
• 0 to 20 mA, where 0 mA represents a sample measurement of 0 (zero) and 20 mA
represents a user selected highest sample measurement (the span).
• 4 to 20 mA, where 4 mA represents a sample measurement of 0 (zero) and 20 mA
represents a user selected highest sample measurement (the span).
In addition to the above, you can specify how the milliAmp output will operate during
calibration, during a fault condition, and during under-range conditions.
Details of the output parameters for the milliAmp outputs are given in Section 6.6.2.
Set up, configure, check, calibrate and use the milliAmp outputs as described in
Sections 6.6.3 to 6.6.6.
