Battery Status – Menu Page 9
This page displays information regarding the
instrument power supply.
The Battery Voltage shows the DC voltage
from the battery. It will read higher when
the instrument is plugged in, so a true
measurement should be taken when it is not
connected to AC power.
The Battery Condition will show the battery
status as Very Low
, Low, or OK depending
on the battery voltage. When the unit is
plugged in, it will show Charging.
The DC Supply is the amount of power that is being generated by the internal power supply.
This will be 0 when it is not plugged in.
The Internal Supply is the amount of voltage that the instrument is seeing. It is the greater
of the battery voltage and the DC supply.
If the instrument has been left unattended in the on position, the battery may be completely
dead. It may be possible to recharge the battery but it will take a few days to accomplish
this. By leaving the instrument plugged in and periodically checking the battery voltage to
see if it is increasing, you will be able to determine if the battery is taking a charge. Keep in
mind that it could take three or four days if the battery is completely dead.
It is recommended that the instrument not be plugged in after every use. The battery will
last longer if it is fully or mostly discharged before it is charged, so it is good practice to only
charge it after it has been used for three or four hours or more. If the battery gets low, a
warning message will appear on the screen, followed by an estimate of the amount of time
until it runs out of power. You will always have at least an hour of run time when you first
see this message.
When it is plugged in to recharge, the instrument can still be used. The unit will recharge
and operate at the same time.
