Display | LCD (service life: 100,000 hours), 4-level backlight | ||
Saved items: rated measurement voltage, comparator upper limit /lower limit values, test mode, | |||
Internal memory | 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 | ||
