MediaGauge? (Model MG-MD) Digital Pressure Gauge
Product Overview
To set the High or Low pressure set points: Press and hold
down the UNIT/SET button for 3 seconds. The
MediaGauge? MG-MD will go into the pressure setting
mode.

indicating low pressure setting. Repeat steps 1 and
2 above to set the 4 digits of the low pressure
settings.
4) After all 4 digits of the low pressure settings are
done press the Button one more time, the
screen will show “Load”, indicating your pressure
settings have been saved into memory.
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.
5) To make sure that the settings are correct, you can
press the
Button to check the value of the low

the MediaGauge? MG-MD digital pressure gauge.
3) Program the MediaGauge? digital pressure gauge
with your low and high pressure set points per the
instructions described previously.
