2.4.2 Battery Monitor
To prevent operation of the Test Set with weak batteries, a battery
test is performed every time the Range Switch is changed. If the
batteries are low, the Pointer will deflect down scale into the Sleep
Zone. It will not respond to any input making measurements impos-
sible. This feature prevents low batteries from providing false read-
ings if they fall below a voltage at which the internal circuitry is de-
signed to operate reliably. Note that even though the Pointer is in
the Sleep Zone, the Test Set is not in a low current mode. After
approximately five minutes, the Test Set will revert to the battery
saving Sleep mode.
2.4.3 Sleep Mode Disable
The Test Set contains a field changeable jumper located on the left
of the small circuit board on the bottom of the large main circuit
board. This is found by removing the four screws holding the RF
shield. This jumper, when in position 1-2, will enable the sleep mode.
To disable the sleep mode, move the jumper to the 2-3 position.
