Unpacking
Initial inspection should include checking for physical dam-
age during shipping and obvious external damage to the
product.
Package contents are defined by your packing list. Each
Order is configured according to customer specifications.
In your inspection, make certain that the contents of your
shipment match the documentation provided by your pack-
ing list.
Place unit on a flat, smooth surface and use leveling feet
(supplied) and a bubble level to ensure that the unit is level
side-to-side and back-to-front.
Installation and Equipment Setup
Electrical Connections
The HM-5250 is equipped with an internal digital switching
power supply, which allows it to be used with most power
configurations throughout the world. The unit is supplied
with an IEC electrical cord with a standard 110V plug.
The HM-5250 arrives ready for operation. Attach the sup-
plied IEC electrical cord to the machine and plug into a
standard wall receptacle for use in the United States. For
locations other than the U.S., replace the supplied electrical
cord with an IEC cord that has the correct plug for your ap-
plication. The supplied cord can also be used by cutting the
standard plug from the cord and attaching the correct plug.
Power Switch
The Power Switch is located above the electrical cord inlet.
The Fuse Compartment is located between the electrical
cord inlet and the Power Switch. The HM-5250 uses a 8.5
amp fuse. To begin operation, attach the supplied electrical
cord, plug it in and press the Power Switch.

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 frequency 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 in-
strumentation 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 instrumen-
tation to the machine. Each input represents a separate channel.
Channel 1 has been assigned to Cell Pressure and is pre-calibrat-
ed. Channel 2 has been assigned to Back Pressure and is pre-cal-
ibrated. Channel 3 has been assigned to Pore Pressure and is
pre-calibrated. And, Channel 4 has been assigned to Volume and is
pre-calibrated. Instrumentation is clearly marked for what channel it
is assigned to.

DO NOT RECALIBRATE!
When your HM-5250 is first turned on, the screen below will
appear.
Navigate to the bottom of this drop-down menu and click
on System Settings (1). You will see the following screen.
From this screen, to confirm your machine instrumentation has
been calibrated, navigate to the Calibration section by clicking
the Menu icon in the top left corner of the screen (1). When you
click on this button, you will see a drop-down menu appear, see
below.

Calibration Input Screen
The Calibration Input Screen (above) is used to monitor and
calibrate instrumentation and assign them to specific chan-
nels of the HM-5250. The Calibration Input Screen provides
a summary of the calibration status of each channel. At this
time, verify the calibration information.
A green box at the left of a channel indicates that the chan-
nel has instrumentation assigned to it and that it is calibrated
and ready for use (1).

Calibration Input Screen, cont.
Each channel has a “Limits On” check box (1). Use the Limits
On to keep the machine from exceeding the sensor limits of
the instrumentation. By selecting this option, before the test
can exceed the limits of the sensors, all tests will stop run-
ning and the motor will stop to avoid damaging connected
instrumentation.
Note: An input cannot be calibrated during testing.
Units (2)
In this field, a calibrated instrument will display the units
that were chosen for use at the time of calibration. This field
can also be used to automatically toggle conversion of units
between lb.-in. and SI units if the need arises.
Value (3)
This field displays the current calibration value. This value
should 1 decimal point accuracy for pressure in psi (kpa) and
3 decimal point accuracy for volume in cm3(1) below. If the
instrument is not calibrated, the unit will read “N/A.”

For the HM-5250, the value for volume is measured through
the position of the stepper motors internally, and pressure is
measured by way of two pressure transducers mounted on
the back of each pressure cylinder.
Export Calibration via USB (4)
Press this button to select calibrations to export via USB. It
is a good practice to export all your calibrations to a thumb
drive. In case of a problem this practice allows you to recover
your calibration data quickly.
