Description:
Benetech manufactures the GT-5306A digital insulation and continuity tester, which also appears under other brand names. This versatile tool serves electrical and industrial fields by measuring the insulation resistance of equipment such as motors, cables, and transformers.
Key features:
- Test voltages: The GT-5306A provides three insulation resistance test voltages: 250V, 500V, and 1000V.
- Multimeter functions: In addition to insulation testing, it has built-in multimeter functions for measuring:
- AC voltage: 0V to 750V
- DC voltage: 0V to 1000V
- Low resistance/continuity: 0Ω to 2kΩ, with a buzzer that sounds at less than 50Ω.
- Large LCD display: A 3½-digit, 20mm high liquid crystal display (LCD) shows a maximum reading of 1999.
- Backlight: The display features a backlight for use in low-light conditions.
- Data hold: It has a data-hold function to freeze the displayed measurement.
- Low battery indicator: A low battery indicator shows when the battery needs replacing.
- Safety features: The tester includes an over-limit alarm, a red alarm light, and a buzzer for high voltage warnings.
- External power option: It can be powered by an external DC9V 1.5A power supply.
