2-Input Modules
Overview
The BetaGauge II is a two-channel, multi-range instrument. You can change ranges simply by plugging
in new input modules, and you may install or remove modules even while the unit is powered up. The calibrator automatically recognizes the module types
and displays the appropriate units. There are two types of modules available for the
BetaGauge II:
BetaPort–DC electrical modulesBetaPort–P pressure modules
You may combine these two module types in the following ways:
One BetaPort–DC electrical module and one
BetaPort–P pressure module, or
Two BetaPort–P pressure modules
WARNING
Do not simultaneously install two BetaPort–DC
electrical modules in the calibrator. The calibrator is not
designed to permit operation with two electrical
modules. Ground potential differences could cause high
current flows through the calibrator which could
damage the calibrator and/or cause bodily injury.
2-1 Modules
Page 29
Installing and Removing Modules
You may insert or remove a module while the calibrator is on or off. If the calibrator is on, the module will self­initialize within 3 seconds and a reading will display on the LCD.
When facing the calibrator, the left module bay corresponds to Channel 1, and the right module bay corresponds to Channel 2.
CAUTION: Use care when handling modules. It is
recommended that you store unused modules in the carrying case supplied
with the calibrator. Careless handling of a module could result in damage to the module's miniature data connector.
Installation Procedure
Use the following procedure to install a module into the BetaGauge II:
1. Insert the connector end of the module into the
appropriate module bay. Make sure the serial number label faces up.
2. Insert the module into the module bay until it is
seated (approximately ¾ inches of the module will be visible).
CAUTION: The keys and offsets on the module connector are designed so that the module can be inserted in one direction only. Excessive force could damage the module or the calibrator.
NOTE: For information on how to select a channel for
performing specific functions, refer to Section 3.
Input Modules 2-2
Page 30
Removal Procedure
To remove a module from the BetaGauge II calibrator, place one hand on the calibrator and use the other hand to firmly grasp the module and pull directly out from
the calibrator. NOTE: If a BetaPort–P pressure module is removed or
disconnected while the BetaGauge II is reading pressure units, the display will show an invalid pressure reading. After a few seconds, the
calibrator will determine that the pressure module has been disconnected or has malfunctioned and the following message will appear: NO MOD.
Input Module Connections
The following paragraphs describe how to connect the BetaGauge II to field instruments for measuring pressure and electrical signals.
BetaPort–DC Electrical Modules
To make electrical connections to the BetaPort–DC module, use standard banana jacks on ¾ inch (19 mm)
centers. The factory test lead connector is a dual banana
connector with the common pin marked by a tab. Replacements are readily available from a variety of
sources including Martel Electronics Corporation. (Consult Factory Sales for details.)
CAUTION: When connecting any electrical
measuring device to an unknown circuit, it is best to de–energize the circuit before
connecting the device. You can then energize the circuit from a safe location.
2-3 Modules
Page 31
Procedure
Use the following procedure to connect the BetaPort– DC electrical module to a field device:
NOTE: Install the module in the calibrator prior to
connecting the module to field devices.
1. Insert the common pin (marked by a tab) on the
dual banana connector into the negative (black) terminal marked with a "–" on the module.
2. Insert the opposite pin into the positive (red)
terminal marked with a "+" on the side labeled "V" for voltage measurement and "mA" for milliamp measurement.
NOTE: The BetaPort–DC module is protected from
damage against misconnection to high voltages up to 120 Volts. In the event that the module is misconnected to a high voltage, the module
should be checked for correct operation by comparison with another device of known performance and similar or better accuracy.
Input Modules 2-4
Page 32
BetaPort–P Pressure Modules
The BetaPort–P pressure modules are fitted with 316 S.S. 1/8" FNPT connections. A variety of connectors and adapters are available from third parties to allow
connection to any type of field device. It is recommended that you use an appropriate pipe
thread seal (such as Teflon tape) with any connector. This improves thread sealing and reduces the likelihood
of galling the threads.
Procedure
When installing a connector on a module, always use a backup wrench to prevent damage to the module or
calibrator. See the illustration below:
Figure 2-1 Using a Backup Wrench
2-5 Modules
Page 33
CAUTION: Failure to use a backup wrench may
damage the calibrator and/or the module and will void the product warranty.
Do not use the pressure connections to support the calibrator.
Pressure Module Media Compatibility
BetaPort–P pressure modules consist of two basic types:
non-isolatedisolated
Consult the calibrator specifications (Appendix B) for details about which modules are isolated and which are
non-isolated. Modules with isolated sensors have an isolating
diaphragm made of 316 stainless steel and may be used with any media compatible with 316 S.S., and are
available for most pressure ranges. CAUTION: Modules with non-isolated sensors may
be used only in the presence of non­corrosive media such as clean, dry, non-
corrosive air or gases. Certain acids may react with stainless steel and should not be introduced into the sensor. Consult with the media or substance manufacturer
for further information.
NOTE: The ranges and the resolution of the various
pressure modules are described in Appendix B, Specifications.
Input Modules 2-6
Page 34
Pressure Module Safety
Always use good safety practices when working with high pressures. Although liquids are considered non­compressible, dissolved and trapped gases can exist in
the system and can store significant energy when compressed under high pressure. Always use good quality fittings that are rated for the pressures you are using and always use safety glasses or goggles.
Overpressure Protection
The sensors used in BetaPort–P pressure modules have excellent overpressure specifications. However, it is possible to damage the sensor if you connect the
module to excessivepressure. CAUTION: Do not connect the BetaPort–P pressure
module to a pressure source greater than the full scale range of the module. Doing
so may damage the module.
If you suspect that a module has been subjected to excessive pressure, compare its performance with an equivalent device to verify its performance.
CAUTION: Using third party devices to provide
external pressure relief is not recommended. A leaking pressure relief device may affect the measurement accuracy.
A module that has been exposed to excessive overpressures may indicate stresed on the calibrator LCD (or EE ERR for earlier versions of firmware). If this happens, you should return the module to the
factory for service.

3-Basic Operations
Overview
The BetaGauge II is a two-channel device. This means that two variables can be measured and displayed
simultaneously. The display data for the channels 1 and 2 corresponds to the modules installed in the left and right module bays respectively. Channel 1 appears in
the top half of the LCD display while Channel 2 appears in the bottom half.
The BetaGauge II uses pressure modules to measure pressure and DC modules to measure electrical signals.
After you have properly installed and connected the input modules to your field instrument, you can begin to perform the following basic operations of the BetaGauge II:
Select channel 1 or channel 2 for performing
specific configuration or modification functions, such as damping or zeroing a module
Specify pre-programmed display units for
calibrating your field instrument
Zero the displayed values for both pressure and DC
modules
Set the damping factor for channels 1 and 2View the serial number, the last calibration date for
the modules currently installed, and full scale range
for pressure modules Program trip detection Each of the above listed operations are described on the
following pages.
3-1 Basic Operations
Page 37
Selecting a Channel for Specific Functions
Some functions, such as zeroing a module or setting a damping feature, require that you specify a channel
prior to performing the function. NOTE: All sample displays representing the LCD in

Basic Operations 3-6
Page 42
Zeroing Pressure Modules
The BetaGauge II has two different zeroing procedures for pressure modules, depending on the zero reference type installed. The two zero reference types include:
Gauge zero. The gauge zero reference type
modules have range labels with markings of PSIG,
“H20, or PSID. Absolute zero. The absolute zero reference
modules have range labels with the marking of
PSIA. CAUTION: On initial power-up, if the pressure
displayed by the module while vented to atmosphere exceeds the reference pressure by 1% of the module’s full scale
pressure range, then the module’s performance should be verified against a pressure reference of equal or better accuracy prior to use in the field.
Zeroing a Gauge Zero Reference Module
Use the following procedure to zero a gauge zero reference module:
1. Install the module in either module bay of the
BetaGauge II.
2. Ensure that the BetaGauge II is on.

Programming Trip Detection
The BetaGauge II has the ability to detect trips from either wet or dry contacts using a BetaPort–DC module. However, this trip detect feature is intended for use with pressure trip devices only.
CAUTION: Do not install two BetaPort–DC
electrical modules in the calibrator simultaneously. The calibrator is not designed to permit operation with two electrical modules. Ground potential
differences could cause high current flows through the calibrator which could damage the calibrator and/or cause bodily injury.
Wet Contacts
The BetaGauge II will detect wet contact trips when the voltage input of the DC module crosses the 12 Volt threshold. The contact wetting voltage should not exceed 48 Volts, and should be a DC potential.
3-15 Basic Operations
Page 51
Dry Contacts
To detect dry contact trips, you must connect dry contacts to the milliamp input of the calibrator’s DC module. The BetaGauge II will detect a dry contact trip
when the input resistance crosses the 800 Ohm threshold.
Hints for Accurate Trip Measurements
There are three areas where it is helpful to have detailed knowledge before setting up a pressure trip detection:
Selecting a field instrument (hand pump or pressure
controller)
Adjusting the pressure sourceRamping the pressure signal
Field Instrument Selection
You can use either a hand pump or a pressure controller as a pressure source for detecting pressure trips. Use the
following guidelines when selecting either of these field instruments:
Hand Pump. Select a hand pump with a Vernier
adjustment knob so that you can make fine
adjustments. Pressure Controller. Select a pressure controller
that has an easy micro-adjustment method.
Basic Operations 3-16
Page 52
Pressure Source Adjustment
Perform the following tasks to adjust the pressure source prior to starting a pressure trip test:
1. Learn the direction (low-going or high-going) in
which the trip will occur and approximately where
the device is expected to trip (in terms of pressure).
2. Use the coarse adjustment control of the pressure
source to set the pressure 5 to10% away from the
trip point.
3. Use the fine adjustment control of the pressure
source to ramp through the expected pressure trip
point.
Pressure Signal Ramping
The slower you ramp the pressure signal, the more accurate the captured trip value will be. This is due not
only to the response time of the pressure trip instrument, but also to the operation of the BetaGauge II. The BetaGauge II takes a pressure reading three times a second, and in between these pressure readings,
it performs background tasks such as monitoring the keyboard, updating the display, monitoring temperature, and performing internal calibrations and checks.
3-17 Basic Operations
Page 53
Preliminary Setup
Use the following procedure to set up the BetaGauge II for trip detection:
1. Connect the alligator clip ends of the test leads
(supplied with the BetaGauge II) to the contacts
you want to monitor.
2. Do one of the following:
If the contacts are wet (have voltage on one or
both sides), connect the dual banana jack to the voltage input of the DC module.
If the contacts are dry, connect the dual banana
jack to the milliamp input terminals of the DC module (for monitoring resistance changes).
NOTE:The BetaGauge II detects wet or dry trips
depending on where the test leads are connected to
the DC module (V or mA jacks). It is not necessary
to set the DC module units for Volts or milliamps.
3. Connect a pressure source to both the installed
pressure module and the pressure trip instrument
under test.
4. Use the Zero key to zero the pressure module as
needed while the pressure circuit is vented to the
atmosphere. To continue with the actual programming of a pressure
trip detection, see the paragraphs below.

READY until the calibrator detects a change of state
from the contacts. Once this change of state occurs,
the display will read TRIP and the pressure input
display will freeze at the point of the trip.
6. Maintain the pressure (or vacuum) from the
pressure source, then press the function key
corresponding to Reset. The BetaGauge II will
once again display READY, in preparation for
detecting the reset point.
3-19 Basic Operations

BetaGauge II allows you to program your own pressure unit. Before setting up a user defined pressure unit, make sure that the pressure module you wish to use is
installed in the module bay of your choice. NOTE: The procedure for programming a user defined
pressure unit involves defining a label (name) for the pressure unit. For the following procedure, we will define an example user unit
of Feet of Water Column at 20°C.

Overview
The BetaGauge II allows you to perform many different calibration tests. In addition, the configurations of these
tests may vary, depending on whether you are using the conventional calibrator mode or documenting calibrator (SYS) mode of operation.
Modes of Operation
The BetaGauge II has two modes of operation: the conventional calibrator mode and the documenting
calibrator (SYS) mode. In the conventional mode, the BetaGauge II monitors
signals to and from a field instrument for the purposes of testing or calibrating that instrument. If you want to
document the field instrument’s input and output values using the conventional mode, you must manually record the information.
In the documenting calibrator (SYS) mode, the BetaGauge II prompts the user to apply input signals to the instrument, and then documents the instrument’s output signal.
NOTE: For more information on how to use the
documenting calibrator (SYS) mode, refer to Section 7.
