Preparations for Measurement
Charging
When the MI70 indicator is turned on, the battery level symbol in the
top left corner of the display indicates the current status of the battery.
It is best to prepare for measurement by having a fully charged battery.
To charge the MI70 indicator, plug in the recharger to the base of the
indicator, and connect the other end to a wall socket. The battery symbol
is animated when charging is in progress.
-
It is not recommended to use MI70 during the first recharging.
After the first charge cycle is complete, you can use the MI70 while
recharging.
-
The duration of recharging depends on the charge level of the
battery pack. 4 hours is a typical recharging time. The
recommended first charging time is 6 hours.
-
When the battery symbol animation stops, the battery is fully
recharged. Disconnect the recharger.
If the indicator will not turn on at all, it is likely that the battery is empty.
If the battery will not charge at all, or the operation time is very short
even after a full charge, see section
Changing the MI70 Battery Pack on
.
Using AA Batteries
You can use regular AA batteries (IEC LR6) instead of the rechargeable
battery pack to power the MI70 indicator. To use AA batteries, you
must remove the rechargeable battery pack, and install a small metallic
clip on the bottom end of the battery compartment. The clip is provided
in a small plastic bag, along with a black plastic plug that you can use
to cover an unused port on the MI70 indicator.
NOTE
The battery clip is not designed to be installed and removed repeatedly.
Install it only if you intend to power the MI70 indicator with AA
batteries exclusively, and not use the rechargeable battery pack.
