Preparing the Instrument for Use

Before you can use the Electronic Balancing Tool, you must decide on a power source.

Power the Micromanometer with the AC Adapter

When the AC adapter is plugged into the micromanometer, the unit automatically turns on, runs a brief
diagnostic check, and briefly lights all segments of the display. It then displays the type of batteries the
unit is set to use (alkaline or rechargeable NiMH) and turns itself OFF.
Whenever the AC adapter is plugged into the micromanometer, the rechargeable batteries are recharged.
(Assuming you are using rechargeable batteries and the switch inside the battery compartment is set to
NiMH. See below.)

Power the Micromanometer with Batteries

When not using the AC adapter, the Electronic Balancing Tool or ProHood
AA-size batteries to operate. These can be either alkaline batteries or rechargeable NiMH batteries. For
your convenience, four NiMH batteries are included with the EBT/PH.
To select the type of batteries you are using:
Turn the unit off and locate the battery cover on the back of the micromanometer (see Figure 4).
