Set the correct Device on your gauge because it will calculate different results depending on which
Device is selected.
9.10 Keep the Keep Rechargeable Batteries in top shape
The DM-2 is designed to recharge NiMH batteries in the gauge, eliminating the need to purchase a
stand-alone battery charger. The charging cycle is designed to fully discharge batteries before
recharging them. This can cause problems if the DM-2 is connected to a power plug for only brief
periods of time.
If the gauge exhibits any of the following conditions, it may be a problem with the rechargeable
batteries:

Short battery life

Will not turn on

Keys will not respond

Loss of power during test
The solution is to reset gauge and charge the batteries, or switch to non-
rechargeable batteries (remember to change the setting to tell the gauge
about the switch in battery type using
[Settings] to set the “Battery Type”.
To charge the batteries:
1. Connect the AC power supply if rechargeable NiMH batteries are already installed.
