1-General Description

Overview

The BetaGauge II pressure calibrator is the most advanced and accurate handheld pressure calibrator

available today. Its 3½ inch diagonal liquid crystal display (LCD), membrane keypad, and user-prompt programming make the BetaGauge II easy to operate.

An illustration is shown below:

Figure 1-1 BetaGauge II

1-1 General Description

Carrying Case

The BetaGauge II comes with a two-section padded vinyl carrying case. It is recommended that you use the case at all times to protect the calibrator from damage due to chemicals, dust, and dirt. The carrying case is

described below: Front Section. The calibrator is secured in the front

section of the case with an elastic strap that fits between the keypad and the display.

Back Section. The back section of the case provides space for carrying three modules, this user guide, and

communications cables. There is also space for fittings or other connectors, if needed.

Bottom Flap. A flap at the bottom of the case is secured with Velcro™. You can loosen the flap to

install and use modules while the calibrator is in the case. Keep the flap closed when the calibrator is not in use to keep foreign material out of the module bays.

Front Flap. The flap at the front of the case has a pouch for holding the calibrator test leads.

Carrying Strap. The carrying strap on the case may be adjusted for comfort as a shoulder strap (or you can remove the strap). It can also be used to hang the calibrator for use in the field.

General Description 1-12

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.
