The Hioki electrical safety testers are designed for insulation resistance and voltage withstand testing of electrical devices and components according to various safety standards. The ST5520 is the fastest insulation tester in the industry, delivering pass/fail assessment in as fast as 50 ms. 25 to 1000 V test voltage with 1 V resolution.
Basic Specifications
- Measurement items: Insulation resistance (Applied DC voltage method)
- Testing voltage: (Measurement range: AUTO/MANUAL setting is possible)
- 25 V ≤ V < 100 V (2.000/20.00/200.0 MΩ),
- 100 V ≤ V < 500 V (2.000/20.00/200.0/2000 MΩ),
- 500 V ≤ V ≤ 1000 V (2.000/20.00/200.0/4000 MΩ)
- Basic accuracy: ±2 % rdg. ±5 dgt.
- 25 V ≤ V < 100 V [0 to 20 MΩ]
- 100 V ≤ V < 500 V [0 to 20 MΩ]
- 500 V ≤ V ≤ 1000 V [0 to 20 MΩ]
- Measurement speed: Fast: 30 ms/time, Slow: 500 ms/time (selectable)
- Display: LCD (service life: 100,000 hours), 4-level backlight
- Internal memory: Saved items: rated measurement voltage, comparator upper limit /lower limit values, test mode, beep sound to distinguish the result, test time, response time, resistance range, measurement speed
- Memory capacity: up to 10 items (can be saved/loaded)
- Comparator setting: UPPER_FAIL: Measured value ≥ upper limit value
- PASS: Upper limit value > measured value > lower limit value
- LOWER_FAIL: Measured value ≤ lower limit value
- Judgement process: Beep sound, PASS / U.FAIL/L. FAIL: light up on LED display, When UL_FAIL, U.FAIL / L.FAIL light up simultaneously, EXT.I/O output, judgement result can be obtained via RS-232C
- Test duration: Definition of test duration: Test duration = Response time + Measurement time
