devices to both module types.
Section 3 explains how to perform basic BetaGauge II
operations, such as specifying pre-programmed display
units, zeroing displayed values, and programming trip
detection.
Section 4 explains how to set user preferences, such as
viewing and programming owner and calibrator
information, turning the keypad beep on and off, and
setting LCD preferences.
Section 5 explains how to set up user-defined display
modes for both electrical and pressure units.
Section 6 explains how to perform the possible
calibration tests using the BetaGauge II.

xii
Section 7 explains how to use the BetaGauge II with
third party software to provide automated computer
aided calibration.
Appendix A provides the dangers, warnings, and
cautions for using battery packs and explains other
battery related information.
Appendix B lists the detailed specifications for the
BetaGauge II.
Appendix C lists the pressure conversion factors for
converting pounds per square inch (PSI) to other
pressure units.
Appendix D describes the necessary service required
for the BetaGauge II. In addition, it explains how to
contact the factory for technical support and how to
arrange for any needed servicing. This section also
includes the Limited Warranty statement.

1-1 General Description
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

General Description 1-2
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.

1-3 General Description

current time and date appears to the left of this
section and the approximate battery voltage
indicator appears to the right.
Channel 1 Input Information. This section
displays the current Channel 1 input reading in
pressure units, Volts, or milliamps.
