Production delay is expected due to the worldwide component shortages. Please contact a Hioki representative for details.


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.


Key Features
- Rapidly assess in as fast as 50 ms
- Quick discharge of residual voltage
- Freely configurable test voltage (set from 25 V to 1000 V, 1 V resolution)
- Contact check function (prevents errors due to poor contact)
- Short-circuit check function (stops potential defects from reaching the market)
- Ideal for battery production lines

Product Warranty Period: 3 years

Included Accessories:

Measurement itemsInsulation 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 speedFast: 30 ms/time, Slow: 500 ms/time (selectable)
DisplayLCD (service life: 100,000 hours), 4-level backlight
Internal memorySaved 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 settingUPPER_FAIL: Measured value ≥ upper limit value
PASS: Upper limit value > measured value > lower limit value
LOWER_FAIL: Measured value ≤ lower limit value
Judgement processBeep 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 durationDefinition of test duration: Test duration = Response time + Measurement time
Function: Set the time from voltage application until pass/fail assessment
Configuration range: 0.045 s to 999.999 s (0.001 s resolution)
Response time timerAfter the start of the test, comparator judgment operation can be prohibited until a set interval from 0.005 sec. to 999.999 sec. (at 0.001 sec. resolution) has passed.
Analog outputDC +4 V f.s.
InterfaceRS-232C (standard), External I/O (External control input, Judgment result)
BCD output (ST5520-01 only)
Power supply100 to 240 V AC, 50/60 Hz, 25 VA max.
