Potentiometers And Test Points At The Converter - Dräger REGARD 2400 Instructions For Use Manual

Adjusting the span
Apply span gas (e.g. 50 %LEL) to the sensor.
The output current can be checked with a voltmeter at the two test points on the left hand
side of the converter "Measuring Point 4...20mA". Alternatively you may refer to the display
of the Dräger REGARD 2400, provided that the corresponding channel is configured cor-
rectly.
Use the potentiometer "Adjust sensor sensitivity" to adjust the output current to the value
which corresponds to the span gas being used.
If a 50 %LEL reference gas is used, the display on the Dräger REGARD 2400 shall indicate
"50"; the voltmeter should indicate 1.2 V (corresponding to 12 mA).
