CHAPTER 3

INSTALLATION AND MOUNTING

OPTIONS

Installing and Recharging the Batteries

1. If you are using alkaline batteries, unscrew the back plate of the

indicator and insert the alkalines. If MM70 is ordered with

rechargeable battery, it is already in place as shipped from the

factory.

2. Recharge the battery as follows: Plug in charger connector to the

indicator. The plug is located at the top of the indicator, covered

by rubber seal. Then connect the charger to wall socket. A

battery symbol in the left corner of the display starts to roll.

3. It is not recommended to use MM70 during the first recharging.

Later on MM70 can be used while recharging.

4. Duration of recharging depends on the charge level of the

battery being 4 hours typical. The recommended first recharging

time is 6 hours.

5. The battery is full when the battery symbol stops rolling.

6. Disconnect the charger.

Turning On the Device

1. Connect the probe to either one of the bottom connectors of the

indicator. To ensure durable connection, screw the metal ring

clockwise until it tightens up. (Respectively, when

disconnecting the cable, first screw the metal ring

counterclockwise until it loosens and then pull out the plug.)
