will be flashing.
(select from 0 to 9). Then press the  Button,
which shifts to the second digit. Again use the 
Button to select 0 thru 9 followed by the  Button
to complete the third and forth digits.
done press the  Button one more time, the
screen will show  on the top, left hand side
indicating low pressure setting. Repeat steps 1 and
2 above to set the 4 digits of the low pressure
settings.
done press the  Button one more time, the
screen will show “Load”, indicating your pressure
settings have been saved into memory.
press the  Button to check the value of the low
pressure setting and press the  Button to check

Typical Wiring Interface
This is a description of an application to interface the
MediaGauge™ MG-MD to a monitoring and control system
utilizing the limit switch output to control a relay and monitor
the output current. The relay will turn on and off based
upon the high and low pressure set points the user
programs into the MediaGauge™ MG-MD digital pressure
gauge.
1) Mount the MediaGauge™ MG-MD digital pressure
2) Connect the supplied mating harness with Din
3) Program the MediaGauge™ digital pressure gauge
gauge on a suitable (1/4” NPT) female fitting. Use
Teflon tape or pipe dope to seal the threads. . Do
not over tighten. Torque to 150 in lbs +/- 1 in lb.
