Charging The Battery - 3M Clean-Trace NGi Luminometer User Manual

2.03 Charging the Battery

The instrument runs on a removable, rechargeable Lithium Ion battery. The sealed battery pack is supplied with
the 3M™ Clean-Trace™ NGi Luminometer and needs to be charged prior to use.
It is necessary to attach the battery pack to the instrument. Locate the battery pack into the aperture in the rear of the
3M™ Clean-Trace™ NGi Luminometer by inserting the bottom of the battery pack first and pushing the battery into
place. Secure the battery pack by turning the fixing screw clockwise using a small screwdriver. Do not over-tighten.
The 3M™ Clean-Trace™ NGi Luminometer may now be charged using the charger supplied. Plug the connector
from the charger into the 3M™ Clean-Trace™ NGi Luminometer as shown in Figure 2, then connect the charger
to an AC power outlet and switch on. Alternatively, the optional docking station is used, insert the 3M™ Clean-
Trace™ NGi Luminometer into the docking station, plug the connector from the charger into the docking station
then connect the charger to an AC power outlet.
The battery in the 3M™ Clean-Trace™ NGi Luminometer will charge fully in approximately 2 hours and will then
be ready for use. The battery level indicator shows the state of charge. Remove the AC power and unplug the
charger from the instrument. If a docking station is used, the charger can remain attached to the docking station
permenantly. In this way, the instrument is always being charged ready for use when it is in the docking station.
The 3M™ Clean-Trace™ NGi Luminometer will display this screen
when it is switched off and charging.
If the 3M™ Clean-Trace™ NGi Luminometer is turned on and
operating with the charger connected, the arrow next to the battery
symbol will be shown.
When switched on, the 3M™ Clean-Trace™ NGi Luminometer will display a continuous indication of battery status
at the top right of the display screen as shown in Figure 1 and as follows:
The removable battery pack is held in place by a single screw.
To remove the battery pack, turn screw counterclockwise until loose
(it is a captive screw so will remain attached to the battery pack) then
remove the battery.
