TERMINAL FUNCTIONS
CALIBRATION
The meter is supplied calibrated to read 000 for 4mA loop current and 1000 for 20mA.
To re-calibrate:
1. Apply 4mA to I+/I- and adjust 'OFFSET' to read 000.
2. Apply 20mA and adjust 'SPAN' to read 1000.
3. Repeat steps 1 and 2 until there is no more adjustment of 'SPAN' and 'OFFSET' required to give desired readings.
SAFETY
To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed 60Vdc. If voltages to the measuring
inputs do exceed 60Vdc, then fit scaling resistors externally to the module. The user must ensure that the incorporation of the DPM into the user’s
equipment conforms to the relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and Laboratory Use).
VARIOUS OPERATING MODES
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.
