NOTES
When you connect the unit to the external power adapter, the
instrument will not recharge if the instrument is asleep (the LED
indicator on the front is not lighted). Press the
Measure
button on the
back of the unit to activate the instrument.
The instrument will never enter
Sleep
mode while it is connected to the
external adapter. The PDA will time out, but the instrument will remain
active (the LED indicator on the front of the unit will be lighted).
Running from the Internal Battery
When the battery icon contains a single bar, the battery level is low, and
a text message displays, prompting you to charge the battery.
When
the remaining power drops to a critical level, a second ―low
battery warning‖ displays, and the battery icon will not contain any bars.
When this message displays you have battery power remaining for
approximately 30 measurements.
BACK UP your data NOW, if you
have not already done so. If you do not, you will not have enough
power to complete the backup process.
When the LED indicator on the front of the unit
repeatedly
cycles
through the green/red/amber color sequences the unit is ready to shut
down. You DO NOT have enough power to complete a backup. You
should immediately connect the unit to the external power adapter.
WARNINGS
When the battery is totally discharged,
everything on the PDA
interface is lost!!!
Back up your data regularly to the flash memory
card so that you do not lose any important information.
If the LED indicator remains amber or red for an extended period of
time, the instrument needs to be reset. To reset, press the
Measure
button on the back of the unit until the light goes out. You can then
resume using the instrument.
