Section 3.0

System Start-Up General

Instructions

The HHC can perform a wide variety of simple and
complex temperature and pressure based measurement,
test and calibration operations. Due to the menu driven
set up procedures the system can be quickly and easily
configured for most any of its measurement functions.
By following the steps in this section you can be ready
to use your HHC to perform basic pressure and tempera-
ture measurement functions in a matter of minutes.

Section 3.1

Battery Installation

Step 1

To gain access to the battery compartment,

remove the bottom end of the strap assembly by
detaching the Velcro connection and pulling the bottom
end of the strap from the retaining pin in the bottom of
the case of the base unit.

Step 2

Open the battery compartment by sliding the

battery enclosure cover out of the compartment opening.
To do this press down on the circular, ribbed indentation
on the battery cover while pushing the enclosure cover
outward with pressure on the two standoffs located near
the pin used to retain the strap on the base unit.

Step 3

note the polarity information for installation of

the two 9 volt alkaline batteries as outlined on the inside
of the battery enclosure.

Step 4

Locate the two 9 volt batteries and the foam

retaining spacer provided in a small plastic bag. Install
these batteries as shown on the diagram in the battery
enclosure. The HHC will operate for approximately 30
hours on the two 9 Vdc batteries. Alkaline batteries are
recommended for use in the HHC system.

Step 5

Insert the retaining spacer between the two 9

volt batteries. This will insure that the batteries will not
disconnect or be shaken loose during normal operation.

Step 6

Replace battery compartment cover by sliding

cover back into position until it locks in place.

Step 7

Replace strap by threading strap through the

programmed into the GQS-RT unit to provide enhanced
accuracy. Each GQS-RT interface module can accom-
modate up to 8 different programmed RTD calibration
curves. Programming of the RT module is accomplished
via an optional software package and any PC compat-
ible computer with an available standard serial com-
munication port. See Appendix E page 75 for probe
connector pin out information.

Section 1.4.4 The GQS-TC1 Quick Select

Thermocouple Interface Module

The GQS-TC1 allows the HHC base unit, when used
with a thermocouple interface module, to perform
temperature measurement. The GQS-TC1 plugs directly
into the Quick Select module bay in the base unit. The
thermocouple is then attactched to the GQS-TC1 module
via a male “miniature thermocouple connector.”

Section 2.0

Unpacking & General Care

General instructions for unpacking and calibrator care
follow.

Section 2.1

Unpacking Product Upon Receipt

Prior to removing the HHC from the packaging material
inspect all cartons for shipping damage. Document any
damage evident in the event that a damage claim must
be made against the shipper. After inspection, remove
the base unit, module(s), manual and any accessories
purchased from the packaging material. Retain the
packaging for use in returning the HHC to the factory
for future recertification or repair.

Section 2.2

Product Storage

The product should be stored in an area that is main-
tained in the temperature range indicated in the storage
temperature in the product specification. The storage
temperature limits are -4 to + 158 degrees Fahrenheit.
Storage of product in environments that will exceed
these temperature limits results in significant risk of
product damage. It is recommended that the product
not be left in closed cars or truck cabs as temperature
damage can easily occur due to the “greenhouse effect”
of closed vehicles or extreme cold temperatures that can
result from winter conditions.

Section 2.3

Product Cleaning

The enclosure of the calibrator is not watertight. As
such, care should be taken during cleaning to assure
liquid does not penetrate the enclosure for the base unit
or Quick Select modules. Cleaning of the product should
be done with a cloth moistened with a warm, mild deter-
gent mixture.
