Step 10 To store the owner/user information displayed
press the EnT key. Pressing the CE key will return the
HHC to the pressure measurement mode. If entry of new
owner information is still required restart the process as
outlined in steps 1-9 above.
Owner information is stored in Electrically Erasable
Programmable Read Only Memory (EEPROM). This
information should only need to be changed or re-
entered when the owner/user changes.
Section 3.5 Removing Quick Select Pressure or
Temperature Modules
Changing Quick Select pressure modules, therefore
changing the measurement ranges in use, is quick and
easy. Simply follow the steps below to change Quick
Select pressure modules.
Step 1 Using the on/off key on the keypad of the base
unit turn the power to the base unit off.
ON
OFF
Step 2 With one hand, hold base unit keypad side down
and press down on the square retaining tab located near
the upper strap pin on the bottom of the base unit.
Step 3 Maintain pressure on the retaining tab and with
your other hand firmly grasp the pressure manifold
that extends from the end of the Quick Select pressure
module and slide the module out of the module bay.
Important Note: Both module bays of the base unit
should contain a pressure module to protect from dirt or
other debris getting into the base unit assembly. If only
one Quick Select pressure module is needed install the
System Protection Module (part number 875X114-01)
supplied with your unit at the time of shipment.
Section 4.0 Key Function Overview
The HHC has a great deal of functionality. Many of the

various on-board firmware functions/
capabilities
.
PORT SEL
Used to select displayed measure-ment
data. Selection includes: reading pres-
sure from either one or both installed
sensors as well as selection of reading

“user” is an operator programmable
engineering unit, allowing the display
of any single engineering unit not
included in the above list. (See Section
8.0 for details.)
MIN/MAX
Displays the minimum and maximum
pressure values measured. (See Sec-
tion 11.0 for details.)
TARE
Allows for subtraction of an operator
selected value from the displayed pres-
sure measurement value for one or two
Quick Select pressure modules. (See
Section 9.0 for details.)
FLOW
Provides ability to measure the flow of
a gas in terms of velocity or volume.
(See Section 14.0 for details.)
*LEAK
Allows testing for leaks in terms
of pressure decay over time or in
terms of leak rate.
(See Section 15.0
for details.)
