SECTION 6 QUICK-SELECT MODULE
OVERVIEW
Quick-select modules are available for measuring a wide variety
of pressure and temperature ranges. They can be “hot swapped”
within the base unit while it is powered on without causing any
damage to the base unit or the module. “Hot Swap” refers to
installing or removing modules while the base unit is powered
on. The base unit will recognize the module and display the unit
of measure in which the module was originally calibrated and
labeled. Quick-Select pressure modules are available in accuracies from ±0.1% to ±0.025% of span.
11
SECTION 6 QUICK-SELECT MODULE
OVERVIEW CONT.
Quick-Select modules when installed in the base unit are 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.
AM2-1 pressure modules are low pressure measurement devices
based on micro machined silicon variable capacitance sensors.
They are intended for use with clean dry, nonconductive, 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.
AM2-2 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.
AM2-RT1 and RT2 modules are RTD temperature measurement
modules compatible with Pt100, Pt1000, Ni120, Cu10, and up to
six user programmable resistance curves. Measurements 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 decimals of resolution.
Accuracy specifications are detailed in the data sheet.
12
SECTION 6 QUICK-SELECT MODULE
OVERVIEW CONT.
AM2-TC1 temperature modules read types J, K, T, E, R, S, B
and N thermocouples and display the measurement in units of
degrees Fahrenheit, Celsius, Kelvin, Rankin or millivolts.
System protection modules AM2-XS are used to protect unused
sensor bays in the base unit from moisture or other contamination ingress as well as EMI/RFI interference.
Calibration Module AM2-CM allows the operator to easily make
contact with internal connection pins necessary to apply the
required voltage levels for recalibration of the HHC base.

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 Datalogs which
can be manually initiated or automatically logged at user definable time intervals between 100 milliseconds and 24 hours.

SECTION 14 d. ZERO FUNCTION
SECTION 14 e. BACK LIGHT FUNCTION
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 programmable back light auto off timer can be used to preserve
battery life. Press any key to reset the backlight auto off timer.

SECTION 14 f. DAMPING FUNCTION
The Damping Function stabilizes a measured pressure signal.
When damping is activated, the value displayed, saved to a
Datalog or transmitted to a journal (eg. To HyperTerminal) is a
filtered value. The filtering is programmable to 16 incremental
levels, allowing the damping function to be tailored to the specific requirements of most any application. The default damping
level is 1. As the damping level is increased, additional electronic
filtering is applied and the response time is slowed. Values are
displayed on the HHC screen, and recorded by Datalogging at
the fastest update rate between 100 and 300 milliseconds, based
on how many inputs are active. As damping level is increased the
update time increases approximately 100 milliseconds per damping level. With a single pressure module installed and damping
set to maximum level 16 the display output can lag by up to 1.6
seconds from the actual process pressure. If two modules are
installed and or voltage/current monitoring is active the system
display and Datalog values lag will also increase. The longest
display lag with two pressure modules programmed for maximum
damping and the voltage/current monitor active is 4.8 seconds.
Set up of Damping Function
When in Measurement Mode:
1. Press DAMP key.
2. Press PORT SELECT key to choose Channel 1, Channel 2, or
both modules.

The first time the DATA STORE key is pressed following power
up of the HHC, a new Datalog file will be created. The Datalog
column headers will be labeled with date, user programmable
module description (default values are Channel 1, Channel 2,
Ext.) and the engineering unit of measure. Programming channel
and tag names are covered in the MENU driven Datalogging
set up section 15f. The first row of the Datalog will be populated
with measurements as shown on the LCD display. Subsequent
presses of the DATA STORE key will create manual data records
into this initial Datalog.

To close a Datalog and prepare the HHC to begin a new Datalog
press the ESC key. The next press of the DATA STORE key will
begin a new Datalog and will continue to record data in the new
log with every subsequent press of the key.
Up to 64 individual logs can be stored in the on board memory
with a total of 16,000 individual records.
SECTION 14 h. TARE FUNCTION
The HHC has the ability to Tare (subtract an operator selected
value) from the displayed pressure measurement value of either
one or two installed Quick-Select modules. This function is applicable to pressure measurements only. This is most commonly
required in applications where a pressure pre-load, such as in a
weighing application, must be subtracted from the displayed pressure measurement. If the HHC is being used with two Quick-Select modules, independent tare values can be entered for each
of the pressure modules. When tare function is active bar graph
displays will indicate actual percentage of full scale pressure not
the tare value. When the HHC is in tare mode the word “tare” will
appear below the engineering units.
There are two methods to select a tare value, automatic and
manual. Automatic Tare Mode will subtract the actual pressure
applied to the module at the time tare function is activated.
Manual Tare Mode allows the operator to enter a pressure value
to be subtracted from the actual pressure applied to the module.
Automatic tare is the default condition. If Manual Tare Mode is
desired go to the section named Program Manual Tare Value
below the next section.
Activate Tare Mode
To activate either Automatic or Manual tare Mode.
When HHC is in Measurement Mode
Press TARE key
Press PORT SELECT key repeatedly to select Channel 1,
Channel 2, or both active pressure modules
Press ENTER
Selected modules are now in Tare Mode. The value displayed is
equal to the actual applied pressure less the tare value.
When TARE function is active the word “Tare” will be displayed
below the engineering units.

SECTION 14 i. mA/V FUNCTION
The HHC has the capability to monitor either DC milliamp current
0-22 mA or DC voltage 0-33 Vdc. Use of this feature requires
connection to the voltage or current source via the 4mm “Banana
Jacks” located above the units LCD. Note that this calibrator can
monitor only one parameter, either voltage or current, at a time.
To monitor voltage connect the negative lead of the voltage
source to the socket labeled “COM” with a black ring surrounding
the socket. Connect the positive lead of the voltage source to the
red ringed terminal labeled “0-33Vdc In”.
To monitor current connect the negative lead to the black ringed
terminal labeled “COM. Connect the positive current source to
the red ringed terminal labeled “0-22mA In”.
Devices under test may be powered by an external power source,
or by the 24 Vdc power supply built into standard (non-intrinsically
safe) HHC base units. See wiring diagrams in section 14j.
Press the mA/V key to activate voltage and current monitoring.
