 Insulation resistance (Applied DC voltage method)

 Testing voltage/ 

 measurement ranges 

 (Auto / Manual)

 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 (2.000/20.00/200.0/4000/9990 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 200 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

 215 mm (8.46 in)W × 80 mm (3.15 in)H × 166 mm (6.54 in)D
