Figure 4: Red light shows that gauge battery is charging

When connected to the computer USB port, the gauge still discharges very slowly. Connection to the

computer USB is just a way to extend the time available on a charge, so that you can run longer tests if you

have a computer nearby.

2.3 Power the gauge on and off – press for 2 seconds

Warning: Gauge does not turn on immediately. You don’t need

to press the screen overly hard. You may break the glass.

Figure 5: Gauge [Home] key and power on/off key

Press the power on/off key and remove your finger. After two

seconds, you will hear a click as the gauge starts up, then the Splash

Screen will be displayed. Press on/off for 2 seconds to power off.

The Splash Screen is visible until the user taps anywhere on the screen

or until the gauge self-check sequence finishes and automatically

displays the Home screen.

Information displayed on the Splash Screen during start up includes:

 Internal gauge software (Firmware) Build and Version Number

 Gauge Serial Number

Upon gauge start up, the Home screen will display the Device, Range, and Result to be displayed settings

that were set on the gauge before it was last powered off, so the user can immediately start testing if they

are using the same equipment.

2.4 Read Results and control the gauge from the Home screen

The Home screen is the main display that allows a user to control the gauge. The gauge includes

convenience functions to support operation of pressure measurement systems with calibrated fans, and

calculate results for air leakage testing.

In this manual, words that are in square brackets indicate keys that can be tapped to change something on

the gauge.
