Battery Calibration
Battery Level is reported in several screens (the main
menu, and screen #200 Ready to Log Data). In order
for accurate reading, the battery must be calibrated.
Uncallibrated battery readings are preceded by a ‘
?
’
symbol. The battery needs to be calibrated if (a) it was
completely discharged, (b) it was removed from the PC
9800, or (c) a new battery was installed.
The DataLogger
™
program must be running to perform
battery calibration. The calibration could take 20
hours.
Follow these steps to calibrate the PC 9800 battery:
1) Plug in the AC adapter and turn on the PC 9800.
2) From the Main Menu, press <3> for System Menu
3) In the System Menu, press <5> to Calibrate Battery
4) Type 123 and press <Enter> for password.
5) The PC 9800 screen should read BATTERY
MANAGER V1.42 at the top, and the screen font is
reduced in size.
6) This process will take 20 hours. (However, you may
abort it any time by pressing the BLUE key followed by
the <I> key to generate an <@>. If you do abort, you
need to press the <Enter> key again to exit the
calibration program and return to the DataLogger
™
program. In addition, if AC power is disrupted during
calibration, the calibration will be aborted, and you
need to manually restart the calibration.)
7) At the end of the calibration, the screen font will be
restored to normal (larger) size, and you need to press
<Enter> to return to the DataLogger
™
program.
8) Press the BLUE key and then the <V> key (
?
key) for
the diagnostics screen. If the calibration was successful,
the third battery status line should read "Calibrated",
and the fourth battery status line should show the
charge and discharge times of the calibration, and the
battery’s capacity.
