EMV 1125
EMV 1125 is an easy to mount LCD digital panel meter. The user need only drill a single 5.5mm /
screw threaded stud through the hole, fitting the washer and tightening the nut provided. The module's 10 connecting wires pass through the hollow stud into the
target application, where they can be easily soldered into place. The module features 200mV full scale input, auto-zero and auto-polarity. A separate screw terminal
adaptor board (T/BLK-4) simplifies connection and calibration.
installation.
SAFETY
To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed 60Vd.c. If voltages to the measuring inputs
do exceed 60Vd.c., then fit scaling resistors externally to the module. The user must ensure that the incorporation of the meter 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).

FITTING THE EMV 1125
Drill a 5.5mm /
module to the panel by passing its screw threaded stud and the wires through the
hole, fitting the washer and tightening the nut provided. Take care not to trap any of
the connecting wires. Do

... SCALING and CALIBRATION A calibration circuit and two resistors (Ra and Rb) may be added on the EMV 1125 or T/BLK-4 board (cut Link La if fitting Ra) to alter the full scale reading of the meter - see table. Note that the meter will have to be (re-)calibrated by adjusting the potentiometer. ...
