      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

      Model No. (Order Code)

      ST5520 Built-in external I/O output
      ST5520-01 Built-in BCD output
      Note: The ST5520 and ST5520-01 cannot be operated alone. Please select and purchase the optional test leads to accommodate your application.

      Basic specifications

      Accuracy guaranteed: 1 year
      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 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 timer After 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 output DC +4 V f.s.
      Interface RS-232C (standard), External I/O (External control input, Judgment result) BCD output (ST5520-01 only)
      Power supply 100 to 240 V AC, 50/60 Hz, 25 VA max.
      Dimensions and mass 215 mm (8.46 in)W × 80 mm (3.15 in)H × 166 mm (6.54 in)D, 1.1 kg (38.8 oz)
      Included accessories Instruction Manual ×1, Power cord ×1, EXT. I/O Connector ×1, Connector Cover ×1
