Resistance measurement
•Operation
General
The DPA/RES allows you to set two independent trip points against
the measurement taken by a resistance based sensor. They are
specially built and calibrated to suit the resistance range ordered. Note:
if the lead length resistance is likely to be significant when installed,
then the unit should be calibrated on site for the most accurate results.
Setup
The alarm relay coils operate according to each setpoint/deadband
configured via front panel multiturn potentiometers. Internal push
fit jumpers determine the alarm type (high or low acting) and coil
energisation (normally energised/de-energised).
