Frequently Asked Questions

What ranges of test voltage are available for insulation resistance?

The TeriLimax insulation resistance tester offers 4 high-voltage settings to choose from: 100V, 250V, 500V, and 1000V, adapting to different commercial and home test specifications.

Are batteries included in the package?

No, standard 1.5V AA batteries (6 pieces required) are not included in the shipment. They can easily be purchased at any home center or electronics store.

What is the benefit of the automatic discharge feature?

When measuring high-voltage insulation resistance, circuits act like capacitors and store a dangerous charge. The auto-discharge safely releases this energy right after testing to prevent shock.

Can this device measure standard household voltages?

Yes, it works as a comprehensive multimeter measuring AC Voltage from 0V to 750V and DC Voltage from 0mV to 1000V with extreme precision.

What is the function of the on-off buzzer?

The continuity buzzer lets you hear instantly if a circuit is closed (shorted or continuous) without needing to take your eyes off your test probes to look at the screen.

What is the maximum resistance range of this unit?

The TeriLimax measures resistance from 0Ω to 60MΩ with high-grade resolution, ideal for everything from precise electronics to rugged power motors.

Does it have a screen backlight or hold feature?

Yes, it features a convenient Data Retention function that locks the readings on the display screen, allowing you to record measurements in dark or cramped spaces.

What is the weight and build material of the tester?

It weighs 419g and is manufactured using high-quality ABS and durable silicone, which provides outstanding hand-feel and high shock absorption on site.
