Storage function
Preserved contents: rated measurement voltage, upper and lower limits of comparator, test mode, buzzing sound when judging, test time, response time, resistance range, measurement speed
Storage: up to 10 groups (saveable/readable)
Test mode: Continuous mode, PASS STOP mode, FAIL STOP mode, Forced End Decision mode (Switching)
Comparison Settings UPPER_FAIL: Measured Value (> Upper Limit Value)
PASS: upper limit value > measurement value > lower limit value
LOWER_FAIL: Measured value < Lower Limit
Decision processing: buzzing, PASS/U.FAIL/L.FAIL L ED lights on, UL_FAIL U.FAIL/L.FAIL lights on at the same time, EXT.I/O output, RS-232C to obtain the decision results.
The test time timer ranges from 0.045 s to 999.999 s (resolution 0.001 s), the time from applying voltage to determining eligibility
After the start of the response time timer test, it is forbidden to set a comparator to determine the action time from 0.005 s to 999.999 s (0.001 s resolution).
Analog output DC+4V F.S.
Interface RS-232C (Standard), External I/O (External Controller Input, Decision Output), BCD Output (ST5520-01 only)
