When completed, the display should become visible – with Black
letters and a White background. If this does not reset the display
condition, the user should Power cycle the unit "OFF", and then
back "ON".
In the event this White Out condition remains, contact James®
Instruments for further repair instructions. (or see Page 70)
(d) Battery Charging Problems
This condition can happen when the Charge Counters have not
been reset for some time, or... if there is a problem with the battery
itself. (Note: The main battery usually lasts ~ 3-5 years.)
Before sending the unit to James®, try to Reset (or zero) the
battery counters in the Battery Status screen. Go to: Main Menu /
System Menu / Battery Operations - press "Enter" to reset the
Charge and Discharge counters to zero. These counters need to
be reset periodically for the battery monitoring circuit to work
properly. Also, Zeroing these counters will change the battery
status value to 100%. This will happen whether or not the unit was
charged.
Therefore, after resetting the counters, charge the unit for at least
4 hours, and reset the counters again. Doing so will provide the
most accurate % status of the battery.
If this does not correct the charging problem, the system will need
to be evaluated further at James® Instruments. (See Repair
Services in the Calibration & Repair section.)
(e) Uploading Data Problems
This condition can happen when first attempting to use the
James® Instruments software on a PC. It is due to the Comports
not being set to the same setting within the software.
