|
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 |
|
Comparator setting |
UPPER_FAIL:
Measured value ≥ upper 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 |
|
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. |
