Revision 4.6 3/2004
Section 1.0 Introduction
Congratulations! Your purchase of the Hand Held Cali-
brator (HHC) calibration system equips you to perform a
wide variety of pressure and temperature measurements.
The general pressure and temperature measurement
capabilities of the HHC are supplemented by application
specifi c fi rmware as well as the availability of optional
data logging capability.
The HHC is a complete pressure calibration system
providing: interchangeable pressure ranges, simultane-
ous measurement and display of two pressure ranges,
measurement and display of current and voltage. The
HHC also provides the ability to perform high accuracy
temperature measurement. Conversion between tempera-
ture and pressure measurement can be done in a matter
of seconds and requires no tools.
A standard HHC system consists of a base unit that
acts as a host for one or two Quick Select modules.
The Quick Select pressure modules are interchange-
able and are available in a wide variety of ranges from
0.25 inches of water to 10000 psi. A brief description
of the main components of an HHC system follows. In
addition, Quick Select modules are available to allow
the base unit to work in conjunction with most standard
RTD temperature probes and thermocouple temperature
detectors.
Section 3 and its various subsections include all the
information needed to begin using the HHC system for
basic pressure and temperature measurement. Higher
level functions are detailed in later sections of this
manual. It is strongly recommended that the pertinent
sections of this manual be reviewed prior to using the
HHC system for higher level and application specifi c
measurement and test activities.
Important : Failure to follow the instructions provided in
this manual may result in personal injury and/or damage
to the instrument, accessories, products under test or
other equipment.
Section 1.3 Base Unit Overview HHC
The base unit functions as the host for the Quick Select
pressure and temperature modules designated in this
manual by the “GQS” prefi x. Each base unit includes
a keypad, microprocessor based electronics and a two
line LCD display. The base unit displays the measure-
ment data transmitted from the Quick Select module(s).
Measurement outputs from two installed Quick Select
modules can be simultaneously displayed. Quick
Select modules for the measurement of either pres-
sure or temperature can be plugged into either of the
2 module “bays” in the base unit. Pressure engineering
units can be independently selected from the library of
twelve factory programmed or one operator designated
engineering unit. Temperature measurement data can
be displayed in degrees Celsius, Fahrenheit, Kelvin or
Rankine. In addition, when used with the GQS-RT1
Quick Select module for temperature measurement with
an RTD temperature probe, the calibrator system can
display the RTD measurement in ohms. The GQS-TC1
thermocouple interface module allows measurement of
mV inputs from –10 to +100 mV.
In addition to displaying two pressure measurements
simultaneously the operator can elect to display pressure
and temperature or the measured value from either of
the two installed Quick Select modules as well as either
a voltage or mA measurement. This allows for the easy
calibration and test of pressure and temperature trans-
ducers, transmitters and switches.
The base unit includes a wide variety of general and
application specifi c measurement capabilities. These
capabilities allow the HHC measurement and calibration
system to be used for basic pressure and temperature
measurement as well as application specifi c pressure
measurement activities. Basic pressure and tempera-
ture measurement capabilities include; max/min recall,
operator programmable tare values, display hold, opera-
tor programmable damping and user selected engineer-
ing units. Application specifi c capabilities include; fl ow
velocity measurement, fl ow volume mea-surement, leak
detection, leak rate quantifi cation and switch testing.
Optional data logging, time delayed data logging and
programmable alarms are also available.
Section 1.4 Quick Select Modules
Overview
The Quick Select pressure module is a calibrated pres-
sure measurement device. Quick Select pressure module
units are available in a wide variety of pressure measure-
ment ranges. The Quick Select RTD and therm-ocouple
interface modules allow the HHC base unit to provide
precision temperature measurement data using standard
RTD (Resistance Temperature Detector) or thermocou-
ple detectors. The GQS-RT1 module allows the HHC to
function with most common platinum, nickel and copper
RTDs, while the GQS-TC1 supports most common
thermocouples.
The Quick Select module communicates with the base
unit via a 10 pin connector. Quick Select pressure mod-
ules slide into the base unit automatically aligning the
female 10 pin connector on the Quick Select pressure
module with the male 10 pin connector in the base unit.
All calibration data is stored in Electrically Erasable
Programmable Read Only Memory (EEPROM) resident
