Allows you to measure insulation resistance more safely by avoiding operation mistakes!!

Hot-line state detection
In any range (MΩ), the hot-line state (30 V minimum) can be detected through the buzzer sound and the red LED illumination. If you press the MEASURE button by mistake in this state, no test voltage will be generated. Thus, the measuring circuit and the equipment involved will not be affected adversely.

Large bolt mark
During the measurement of MΩ, a large bolt mark is illuminated on the LCD with the buzzer sound, allowing you to find that voltage is generated.

More ingenuity
To select the highest test voltage range, you need to turn the rotary switch while holding down the 0Ω ADJ button. This design feature prevents the highest test voltage from being generated by an operation mistake.

Easy to use & tough body
An easy-to-hold body with a portrait design has been adopted to ensure stable measurements. The tester comes with a strap, and uses less slippery elastomeric material for its lateral sides so that the user can grip the tester more firmly.

Automatic data hold
After measurements have been finished, the last measured value can be held automatically. Unlike an analog tester, you do not need to check the reading during measurements and therefore can comfortably concentrate on the object under measurement.

Bargraph just like analog meter
A large logarithmic bar graph is provided to enable the user to check the measured value like using an analog tester.

Large display with backlight
The backlight allows you to check the measured value even in a dark place. Since the rated voltage output can be checked with the green LED, you can find whether the measurement is being carried out properly.
