When starting measurements with external trigger input
When the trigger source (p. 27) is set to EXTERNAL, a measurement starts with a trigger input to TRIG-IN
(pin 20). The following figure shows a timing chart including the INDEX (pin 22) and EOM (pin 21) signal
outputs.
Monitoring judgment results
In resistance measurement, OHM-UP (pin 14) is at low level when the judgment result is UP and OHM-
LOW (pin 15) is at low level when the judgment result is LOW.
In voltage measurement, V-UP (pin 17) is at low level when the judgment result is UP and V-LOW (pin 18)
is at low level when the judgment result is LOW.
Item Time
T1: Trigger input pulse width 1 ms or more
T2: Delay The time set with delay (p. 28) . 5 ms minimum.
T3: Measurement time Measurement time × average count
Measurement time: Time set with the sampling speed
(p. 15) .
Average count: Average count set with the average function (p. 16) .
T4: Computation time 0.3 ms
T5: EOM signal output (HOLD) When EOM (p. 39) is set to HOLD. Holds low level until the next TRIG-IN is
detected.
T6: EOM signal output (PULSE) When EOM (p. 39) is set to PULSE. Outputs a pulse for the specified time.
T7: Judgment delay 0.2 ms
