BATTERY INSTALLATION (Refer to Figure 2)
CAUTION: The batteries can be zinc carbon, alkaline or rechargeable. Do not mix
battery types.
The CEL-62X Instrument requires three AA batteries. Remove the battery compartment
cover. Check correct polarity. Fit the batteries. Refit the battery cover. Press and release
the
ON/OFF Key. Check the battery condition symbol shows the battery has a good
charge.
Note: For long term tests, where the batteries may become exhausted, use a 12VDC
supply to power the CEL-62X. The 12VDC can be plugged in at any time and will be
automatically used instead of the batteries. When downloading data to a PC the CEL-
62X can be powered by the USB connection. The 12VDC or USB connection will not re-
charge batteries. With 12VDC or USB connected the battery condition symbol will show
full charge and not the actual condition of any installed batteries.
To extend battery life, if the CEL-62X is not making a measurement run and there are no
key presses, the instrument will automatically turn off after a period of 5 minutes. This
auto power off facility is disabled when the CEL-62X is powered from 12VDC or USB.
The auto power off facility is independent of the backlight time settings – see paragraph
E – Set Backlight below.
