Power Options
The Product can be powered with the internal, high-capacity NiMH battery and/or the
universal power supply (90 V ac to 250 V ac) that charges the battery pack. The universal
power supply can power the Product at the same time it charges the battery pack. A fully-
discharged battery can take a maximum of 14 hours to recharge. When the Product is first
received, plug it into the universal power supply for that period to ensure the Product is
fully charged.
Product Startup
When you turn on the Product, it goes through a short self-test. The display shows the
current firmware version, auto-shutdown status, and the range of the internal pressure
sensor. The Product also shows the warning “ FOR USE WITH DRY GAS ONLY”.
A minimum 5-minute warm-up is necessary to get the rated accuracy of the Product. If
there are large changes in ambient temperature, a longer warm-up is necessary.
Pressure ranges must be zeroed each time the Product is started. See the “Zero Function”
section for instructions to zero the pressure sensor displays.
Product Menus
The menu bar at the bottom of the display is controlled with the softkeys or arrow keys,
this depends on which menu is in use. Use the menu bar to navigate the Product menus.
The menus are explained in the subsequent sections. A menu map is shown in Figure 7.
