DPM 942
A loop powered indicator giving an accurate, zero corrected indication of 4-20mA loop current. Calibration is by two 20-turn cermet
potentiometers which allow sensitive adjustment of the instrument. The meter is housed in a robust carrier, which can be bolted in
place or panel mounted using the low profile bezel and clips provided.
CUSTOM SCALING
For alternative scaling to the standard 0 - 1000, cut Link 8
and short Link 7. Add two resistors R12 and R13 which
will set the basic scale of the meter. The highest practical
value for the R12 and R13 series combination is 12R. To
select your desired scaling, use the following formula:
R12 + R13 = Full Scale reading at 20mA
Re-calibrate as necessary.

... ON-BOARD LINKS: In order to quickly and easily change operating modes for different applications, the meter has several "on-board links". They are designed to be easily opened (cut) or shorted (soldered). The DPM 942 is powered from the 4-20mA signal loop and needs no other power supply. Ensure correct polarity when connecting.
