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 modules
 BetaPort–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

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

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

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

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

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-isolated
 isolated

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

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.

These offsets typically occur under the following

circumstances:

 Each time you turn the calibrator off and on.
 Each time you install a new module.

 Each time you select a new engineering unit

(pressure module only).

Basic Operations 3-6

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

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 source
 Ramping 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

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

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.

Basic Operations 3-18

Dis. Enab Reset

In the above example:

x = the channel number of the DC module.

3. To enable the trip detect status, press the function

key corresponding to the menu item Enab, and the

electrical signal display will read READY.

4. Close the pressure circuit of the trip instrument,

then slowly re-apply pressure (or vacuum) to the

pressure circuit.

5. The electrical signal display will continue to read

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

7. If possible, use the micro-adjustment of the

pressure source to ramp towards the reset point of

the pressure trip device. The display will again

display TRIP when the BetaGauge II detects the

reset point.

the following:

 Vent the pressure source.

 Disconnect all test circuits.

 Press the function key corresponding to Dis. to

disable the trip detection feature.

 Press the CLR key to return to the Setup

menu.

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.
