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

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)
