Look at the bottom, you can see a charging line. Thick line means FAST(100mAh), thin line means SLOW(45mAh).
You can see RS232C usage line a little bit above the charging line. Thick line means
WIRED-SERIAL used, thin line means IR port used period. (If you use CARD-MODEM, more
thick!)
BATTLOG has 3 graph-view mode. Each mode has a good point.
BATTLOG.COM TSR module will measure voltage of HP200LX main batteries each 20 seconds. while 5 minutes, it collects 15 sets of voltage-data. In this view-mode, BATTLOG displays its average voltage graph on HP200LX.
This mode may be useful for general purpose, and fastest.
In this mode, BATTLOG displays bar from minimum to maximum voltage, like a candle. When you turn on your lovely HP200LX, main battery voltage drops momentary. You can observe such a condition in this mode well.
Especially, using FLASH-MEMORY card, the candle will be tall. Because FLASH memory card eats(spends) a lot of battery power when it turn on. In my case, I use IBM-FLASH card, candle may be much longer than SANDISK-FLASH user's.
While using CARD-MODEM, candle will be longer.
In this mode, you can see three graphs on HP200LX. One is average graph, other one is maximum graph, and the other one is minimum graph. Just looking at this graph, you'll easily understand the condition of the battery.
I usually use this mode. Unfortunately, display speed is slower than the other mode.
But I recommend this mode
