Discharge Function:
The tester automatically discharge when you turn off the MEAS switch. The segment bar extends if there is any residual voltage in the circuit under the test. You can make sure the discharge is complete by checking that the segment bar disappears from the display. Under this condition, the tester is ready to enter voltage measurement mode.

AC Voltage Measurement:
The tester enters AC Voltage measurement Mode when you turn on the power (rotary) switch.

Auto Hold:
The tester retains the measured resistance for approximately 5 seconds after the MEAS switch is turned off.

Display:
3 1/2-Digit LCD; 4000 Count Maximum; 42-segment, logarithmic bar graph; Over range input indicator- the OL symbol comes on if the measured value exceeds 200count (200.0 range)

MΩ range selection:
Fully Automatic ranging

Range Step-up:
The tester shifts the range one step upwards for input levels higher then 4000 count.

Range step-down:
The tester shifts the range one step downward for input levels lower the 360 count.

Dimensions (main unit):
Approx. 120(W)x110(H)x60(D)mm

Weight:s
500g (main unit and batteries only)

Batteries:
Six AA (R6P) batteries
