– Error in Charging
The Error Condition will also be indicated if the charger senses and problem with the battery
being charged. To reset the error condition, unplug the charger from the power adapter for a
few seconds, and then reconnect it. If the Error occurs again, there may be a defect in the
battery that will prevent safely charging.
Charging Time
The 7.4V 2200mAh Lithium-Ion batteries supplied with the inclinometer system will take
approximately 80 minutes to fully charge if they are depleted.
Note
RST strongly recommends that all batteries should be taken out into the field fully
charged at the beginning of each day.
Be aware that cold temperatures can also have an effect on the performance of the
batteries. Expect a somewhat shorter operation in extremely cold temperatures. Under
adverse conditions, it is recommended that extra batteries be taken to the field, where one
can be charging in between readings of several boreholes. The reel batteries are a standard
camcorder battery and are readily available.
Note
The batteries will self discharge when not in use whether they are installed in the
inclinometer reel or not. Batteries can be kept fresh if recharged on a regular basis.
Upon replacement of the battery, ensure to align the battery contacts with the contacts in the
Reel hub to allow proper operation. Installation is the exact opposite of removal. Please
ensure that the battery contacts line up with the contacts contained within the hub for correct
operation.
Battery Life
A single Reel battery has the ability to last for up to 1 week on standby mode (i.e. no
connection to the Ultra-Rugged Field PC). However, it is a good practice to turn off the Reel
power whenever the survey is complete, as leaving the power on will eventually drain the
battery. At room temperature, while taking readings, battery life is approximately 30 hours.
In extreme environmental conditions (extreme cold or hot temperatures) fully expect useable
battery life to decrease. It is always a good practice to take 2 or more fully charged batteries
out in the field before performing inclinometer survey work.
