services. ANSI B40.1 is available from:
ASME
345 East 47th Street
New York, NY 10017
Pressure – Select a range so that the maximum applied pres-
sure will never exceed the upper range limit.
Vibration – Excessive vibration could cause loosening of
components resulting in loss of instrument accu-
racy or failure to provide valid data.
Pulsation – Excessive pressure pulsation could result in
fatigue failure of the pressure element.
Temperature – Operation of the instrument in an environment
where temperatures are in excess of design rat-
ings may result in loss of accuracy and failure.
Process – Pressure boundary materials must be resistant to
the process media. Failure to assure compatibility
may result in pressure sensing element deteriora-
tion or failure. Instruments used on high pressure
gas, or potentially hazardous service, such as
oxygen should be carefully selected in accordance
with the recommendations of ANSI B40.1.
Hazardous Location – Only approved explosion proof or intrin-
sically safe instruments should be used in hazard-
ous locations.
Electro-Magnetic Interference – Instruments should not be
used
in locations where EMI/RFI conditions exceed

sure and temperature modules. The base unit includes two
bays for installation of pressure or temperature modules, an
LCD graphic display with back light, a key pad, a USB micro B
receptacle for communication with a PC, an SD memory card
slot and banana jack connections for DC voltage supply and
signal monitoring. The enclosure is rated to IP65 water resis-
tant.
When pressure and or temperature modules are installed and
the base unit is powered on, it will briefly display the brand
name, data regarding installed modules. Then the HHC will
go into measurement mode where it will display up to three
values as well as their respective engineering units of measure.
The base unit is pre-programmed with twelve units of pres-
sure measurement, four units of temperature measurement,
DC voltage 0-30 VDC, DC current 0-20 ma and also allows the
user to program a custom pressure unit of measure. In mea-
surement mode, the display will show Battery status, USB con-
nection status, one or two vertical bar graph indicators indicat-
ing percentage of full scale pressure and other user interface
and warning messages when applicable.
The calibrator is equipped with internal memory capable of
storing up to 16,000 records. Datalogs can be transferred to an
optional on board SD memory card to clear internal memory
and allow further data collection. Datalogs can be transferred
to a PC from the SD card and are presented in .csv files which
can be opened by Microsoft Excel software.

referred to as Channel 1 and Channel 2. Channel 1 is always
the module on the left side of the calibrator when it is held
upright with modules at the top of the calibrator and the LCD
display facing the operator. Channel 2 is on the right side when
the base unit is held in the same position.
HM2-1 pressure modules are low pressure measurement
devices based on micro machined silicon variable capacitance
sensors. They are intended for use with clean dry, nonconduc-
tive, noncorrosive gases. They are available in ranges from
0.25 to 200 inches of water column and can be configured to
provide differential, gauge or compound readings.
HM2-2 are high pressure measurement devices. They are
single-port modules based on sensors capable of measuring
gauge, absolute, compound or vacuum with ranges spanning
from vacuum to 5 psi to 10,000 psi. All wetted parts are 316
stainless steel (except for 10k psi module which has 17-4ph
stainless steel) and are intended for use with any pressure
medium compatible with stainless steel.
HM2-RT1 and RT2 modules are RTD temperature measure-
ment modules compatible with Pt100, Pt1000, Ni120, Cu10,
and up to six user programmable resistance curves. Measure-
ments can be displayed in degrees Fahrenheit, Celsius, Kelvin,
Rankin or ohms. The setup menu allows the operator to choose
configurations for 2, 3 or 4 wire RTD probes. In addition, the
setup menu also allows selection of 1, 0.1, 0.01 or 0.001 deci-
mals of resolution. Accuracy specifications are detailed in the

Connect the pressure port(s) of the Quick-Select pressure
module(s) to be used to the pressure source to be measured.
If a gauge pressure measurement is to be made using a low
differential pressure Quick-Select pressure module, be sure to
connect the pressure to be measured to the high pressure port
on the Quick-Select pressure module.
Note: When making connections to pressure ports on Quick-
Select modules always use proper tools such as the proper
size wrench, slip joint pliers or locking jaw pliers to hold the
stainless steel manifold and use a second tool such as a prop-
erly sized wrench to tighten the connection. NEVER tighten the
fitting by holding it only in the base unit
For temperature measurement, connect the RTD probe to be
used to the Switchcraft connector on the interface module then
proceed to Section 15j or 15k for instructions on setting up the
calibrator for temperature measurement.

SECTION 13 KEY FUNCTION OVERVIEW The most common functions are accessible by dedicated keys
on the keypad. More complex and less often used functions
and programmable features are accessible through an easy-
to-navigate MENU system. A number of the keys have differ-
ent functions depending in which mode the HHC is operating.
These keys have white and yellow lettering and icons. The
white lettering indicates the primary key function. Yellow is the
secondary function. A brief overview of the keypad keys and
functions follows:
Power Key is used to
switch the HHC on and off.
The MENU key is used to
enter and exit the program-
ming MENU
To Zero installed Quick-
Select Pressure modules
Escape Key to go back one
level when in MENU Mode
or to escape any special
display mode. Also aborts
auto datalogging.
To select installed modules
to apply various functions.
In MENU Mode, to incre-
ment a selected parameter
up once per press.
To switch back light on
and off.
To adjust damping level of
installed module(s) in Mea-
surement Mode. In MENU
Mode it is used as a LEFT
ARROW key.
Multi-function key. In
Manual Datalog Mode,
stores one data point of
value presently shown on
the display. When in Auto-
matic Datalog Mode will
begin or end auto logging
at the programmed inter-
val. When in programming
mode, it is used as the
Enter key to save selected
parameters.
Used to activate the tare
function on installed Quick-
Select modules when in
Measurement Mode. In
MENU Mode used as
RIGHT ARROW key.
To activate measurement

SECTION 14 e. BACK LIGHT FUNCTION
SECTION 14 d. ZERO FUNCTION
During any programming operation pressing the ESC key will
cause the HHC to exit any special display mode or, step back
one programming level if in Programming Mode.
PORT SELECT function is used in several programming appli-
cations including zero, min/max, tare and damping. This allows
the user to choose between installed modules to which an
action is to be performed. PORT SELECT is enabled follow-
ing the initialization of a desired function such as zero. The
selected module(s) will be indicated by having a rectangular
box surrounding the measurement indication. Pressing the
PORT SELECT key repeatedly will allow the user to select the
Channel 1 , Channel 2 or both channels if applicable. When
desired channel (s) are selected the ENTER key is pressed to
finalize the selection.
The default Data Storage mode is manual and is described in
section 14g and 15f. The HHC is capable of storing pressure,
temperature, voltage or current data for any combination of
installed modules, voltage or current inputs that are active, up
to three simultaneous data points. Each data record will include
a time stamp and up to three measurement values. Headers in
the Datalog report label columns with date, user-programmable
module description (default values are Channel 1, Channel
2, Ext.) and the engineering unit of measure. Up to 16,000
records can be recorded. Data records are grouped in Data-
logs which can be manually initiated or automatically logged at
user definable time intervals between 100 milliseconds and 24
hours.
Utilized to remove zero offset, up to 10% of full scale range,
when zero pressure is applied.
1. Press the ZERO key. PORT SELECT MENU is entered with
the Channel 1 module selected.
2. Use the PORT SELECT key to select Channel 1, Channel 2
or both Channels.
3. Press ENTER to zero the selected module or modules, or
press ESC to cancel and return to Measurement Mode
A module must be installed in the HHC base unit to be zeroed.
Additionally, it must be a pressure module, and must be within
10% of full scale of its factory programmed zero.
In the event an attempt is made to zero a module that is
absent, or which is not a pressure module a warning will be
displayed in the notice area stating:
“CH(X) not a pressure mod”.
In the event an attempt is made to zero a module that is more
than 10% of full scale from its factory programmed zero, a
warning will be displayed in the notice area stating:
“CH(X) zero out of bounds”
Press the Back Light key to toggle the light on/off. A user pro-
grammable back light auto off timer can be used to preserve
battery life. Press any key to reset the backlight auto off timer.
