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 compartment. Unscrew and
remove the battery compartment cover. Remove the battery pack noting the position of
the power leads. Insert the new battery so that the leads are in the same position as the
battery you just removed. Now replace the cover and tighten the screw for the cover.
Note that The Portable Interrogator 400 will restart itself. This is normal and will happen
each time you change the battery. Note that even though The Portable Interrogator 400
restarts, no meter readings are lost.
BATTERY MONITORING
As you use The Portable Interrogator 400, it constantly checks the power in the battery.
If the battery power starts running low, The Portable Interrogator 400 will display a
yellow BATT light. If the battery power is too low to interrogate a meter, The Portable
Interrogator 400 will display a red BATT light. You’ll always know the status of The
Portable Interrogator 400 battery just by monitoring the BATT light.
