battery is 4 hours. The lithium battery pack is designed with a feature that senses when
the battery is fully charged and stops the charging process to eliminate over charging.
Once a battery pack has been fully charged, it is recommended that it be removed from
the charger.
CHANGING THE BATTERY
Changing the ReadAll’s battery is quick and easy. Because of the ReadAll’s design,
meter readings will not be lost when changing the battery. However, the ReadAll should
be turned off when replacing a battery. If the ReadAll is on, press the power button to
turn the ReadAll off.
First, if you have the hand strap connected, disconnect the back portion of the strap from
the bottom of the case. Underneath the strap is the battery. Unscrew and remove the
battery. Insert the new battery and tighten the screw. Note that no tools are required.
Simply unscrew the old battery, remove it, insert the new one, and screw it in! Once the
new battery is installed, the ReadAll will restart itself. This is normal and will happen
each time you change the battery. Note that even though the ReadAll restarts, no
meter readings are lost.
BATTERY MONITORING
As you use the ReadAll, it constantly checks the power in the battery. If the battery
power starts running low, the ReadAll will display a yellow BATT light. If the battery
power is too low to interrogate a meter, the ReadAll will display a red BATT light.
You’ll always know the status of the ReadAll battery just by monitoring the BATT light.
Note that if the ReadAll is getting power from the cradle (and not from the battery), the
battery checking is not needed and not performed.
