Note: If you set the
repeat time to "000:00" (0 days, 0 hours), the automatic
validation/calibration will only be performed once, on the specified start date, at the
specified start time. You will therefore need to initiate any subsequent automatic
validation/calibration: see Section 6.2.1.

Configuring and using the mA outputs
5.16.1
Overview
The
milliamp output provides a constantly updated output, in which the current represents the value of
gas sample measurement.
The
analyser allows you to specify two separate range configura�ons for the milliamp output: Range 1
and Range 2. The current range is shown on the Measurement screen (see Figure
6
):
is shown if Range 1 is selected.
is shown if Range 2 is selected.
The mA output can be selected as:
•
0 to 20 mA, where 0 mA represents the lowest sample measurement and 20 mA
represents the highest sample measurement in the range you have specified.
• 4 to 20 mA, where 4 mA represents the lowest sample measurement and 20
mA
represents the
highest sample measurement in the range you have specified.
In addi�on to the above, you can specify how the milliamp output will operate during calibra�on, during
a fault condi�on, and during under range condi�ons.
