Preparing the Instrument for Use
Before you can use the Modular Balancing Tool, you must decide on a power source.
Power the Micromanometer with the AC Adapter
The AC adapter can be used to power the instrument or to charge the NiMH batteries when the
DIP switch in the battery compartment is set to NiMH. If the DIP switch is set to Alkaline, and the
AC power adapter is connected then the batteries will be bypassed and the meter will be powered by the
AC adapter. Be sure to provide the correct voltage and frequency, which is marked on the back of the
AC adapter.
Power the Micromanometer with Batteries
The micromanometer is designed to operate with either alkaline or NiMH rechargeable batteries. Battery
life will be shorter if NiMH batteries are used. If NiMH batteries are used the DIP switch will need to be
changed. Refer to the next section on setting the
battery selection switch .
Note
If using NiMH batteries, then they will need to be charged prior to use. Charge time is 4 hours.
Carbon-zinc batteries are not recommended due to the danger of battery acid leakage.
To select the type of batteries you are using:
1. Turn the unit off and locate the battery cover on the back of the micromanometer (see Figure 5).
