Installing Batteries

Providing power

You can power the instrument with internal batteries or from an external power source. There are two optional sources which include a universal power supply 9V/.66A 2.1 mm and an auto DC jack cable 12V. (See Optional Parts, in Appendix A for more details.)

Installing Batteries

The instrument requires four AA-sized batteries. Disposable alkaline batteries are satisfactory, but you may also use rechargeable Nickel Metal Hydride (NiMH) batteries.

•Rechargeable batteries ~ The instrument does not contain a recharging circuit. Recharge batteries externally using the recharging device available from 3M or a compatible device available elsewhere.

•Selecting batteries ~ Do not mix battery types or batteries with significantly different charge levels.

NOTE: To avoid possible battery leakage, remove the batteries when the meter is not in use for prolonged periods.

To install batteries

2.Lift off the lid and set aside. Wedge out the four batteries.

3.Replace the batteries with fresh batteries, taking care that you orient all batteries with the positive ends toward the base, as shown in the drawing.

4.Re-insert the lid by fitting its locator pins into slots in the base end of the battery compartment. The lid should fit snugly when correctly inserted.
