Section 3.2 Installation of Quick Select Module
in a Vacant Module Bay
Caution: Quick Select modules should be installed with
the power off on the base unit. Failure to turn the base
unit off prior to changing pressure measurement mod-
ules could damage the instrument or module electron-
ics or “lock up” microprocessor operation. If power is
inadvertently left on and the base unit locks up (looses
communication) after changing Quick Select modules,
simply power down the unit and restart.
Refer to Section 3.5 for the procedure to remove a Quick
Select module.
To insert a Quick Select module follow the process
below.
Step 1 Make certain the power is off on the base unit.
Step 2 Hold the base unit, in one hand, with the keypad
side down.
Step 3 Holding the Quick Select module to be installed
in the other hand, align the module with the locking tab
up, with the module bay on the base unit.
Step 4 Slide the Quick Select module into the base unit
until the retaining/release tab pops into the square cutout
in the module bay of the base unit. This will lock the
Quick Select module into the base unit.
Step 5 Installation of the Quick Select module is now
complete. If an GQS-RT1 or GQS-TC1 interface module
is to be used plug the appropriate temperature detector
into the connector on the module. To set up the HHC
and temperature module combination proceed to section
16 for RTDs or section 17 for thermcouple detectors
Important Note:
If only one module is to be used, install the Quick
Select System Protection module provided. Follow
the same procedure to install the system protection
module as that used for a standard pressure
measurement module. Both module bays of the
base unit should contain a Quick Select 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 GQS-XS) supplied
with your unit at the time of shipment when using
the HHC system.
Section 3.3 Starting-Up the HHC System
After the desired Quick Select pressure module(s) or
Quick Select temperature measurement interface module
and probe has been installed the HHC can be started up
as follows:
Turn the system power on by pressing the on/off key on
the instrument’s key pad.

During the start up process the HHC will display the fol-
lowing information:
First Screen

where xx.xx is a numerical value representing the
firmware revision level installed in the base unit. The
firmware version is updated/changed as enhancements
are added to the HHC.
