NOTE:

The meter will not operate when the battery

charger is connected to the charger jack.

Description

To begin making field measurements, connect the probe

to the meter. Turn the range switch clockwise,

increasing the instrument's sensitivity until an up-scale

meter reading is obtained. Readings will be most

accurate when the selected range yields maximum needle

deflection without lighting the Over Range LED. When an

over range indication occurs, select the next larger range.

Since the meter movement is protected against deflection

past the top of the meter scale, the "Over Range" LED

must be used to determine an over range condition.

The probe utilizes three mutually-perpendicular concentric

coils it is not necessary to rotate the sensor to obtain a

maximum indication on the meter.
