Basic specifications

Measurement items	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 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)
Accessories	Instruction Manual ×1, Power cord ×1, EXT. I/O Connector ×1, Connector Cover ×1
