Remember, your HM-5250 Pressure Controller includes all the
necessary instrumentation, which is already calibrated and
assigned to an Input and will not need calibration, however you
should confirm that the instrumentation has been set up and
calibrated, that you have plugged them into the correct channel,
and that you check with your QC/QA program to set up a fre-
quency of calibration schedule.
Initial Set Up
Once you have installed the instrumentation into the correct inputs,
your rear panel should look like the photo on the previous page.
Below are photos of an instrumentation input and the instrumenta-
tion plug. Install the plugs into the inputs by lining up the guide at
the bottom of the plug with the slot at the bottom of the input.

Instrument Inputs (3)
The back panel features four (4) inputs for connecting instrumentation to
the machine. Each input represents a separate channel. Channel 1 has
been assigned to Cell Pressure and is pre-calibrated. Channel 2 has been
assigned to Back Pressure and is pre-calibrated. Channels 3-4 are not con-
nected to any sensors, and are inactive.
