APPLICATION
The multimeter is a pocket-sized 3½-digit digital multimeter for measuring DC and AC Voltage, DC Current, Resistance, testing Diode and continuity. Overload protection and low battery indication are provided.
FEATURES
-
This switch is used to select the functions and desired ranges as well as to turn ON/OFF the meter. To extend the life of the battery, the switch should be in the “OFF” position when the meter is not in use.

measurement. There is no fuse in the built in circuit for “10A” jack. To use safely, each measurement can not last for more than 10 seconds, and the interval between each measurement must be more than 15 minutes.
SPECIFICATIONS
-
Diode: Testing Voltage about 2.4V, current about 1mA. The forward voltage drop in mV will be displayed.
-
Buzzer: When you measure for continuity, the buzzer will sound if the resistance is less than 50Ω
-
Dimensions:130x70x28mm(length x width x height).
-
Weight: Approximately 146 grams.
