1.4 Charging the Battery Pack
The 978 is powered by six nickel-cadmium batteries in a removable
battery pack. The instrument’s batteries should be charged before use. The
unit can be operated while the batteries are being charged.
Before plugging in the AC adaptor, make sure that the voltage indicated
on the adaptor complies with the AC line voltage in your area. If not,
contact X-Rite or your Authorized Representative.
The instrument batteries should be fully charged in 14 hours and should
provide approximately 1000 measurements. Charging the batteries for less
than 14 hours will reduce the operating time of the unit. If the unit has not
been used for several weeks, recharge for approximately 24 hours.
Charging Tips
* Always run the unit down to the point where the "BATTERIES
LOW" message is displayed. Then charge the unit before the next
message "CHARGE BATTERIES" is displayed.
* Leaving the unit plugged into the AC wall outlet for extended
periods of time (over 48 hours) may shorten the battery life.
* If the instrument is to be stored for an extended period of time (over 6
months), the battery pack should be removed from the unit.
AC Adaptor Connection Procedure
1. Plug the small connector
end of the AC adaptor
into the adaptor jack on
the back of the
instrument or the battery
pack.
2. Plug the adaptor into the
AC wall outlet.
☛ The unit will not lose any of the preset
information (i.e., cal, setups, etc.) if
the battery pack is removed.
