• Event trigger mode
All event trigger inputs are negative logic (ON at Low signal, unchangeable).
TIMING signal: Invalid in ‘Normal’ mode.
Measures at the falling edge in ‘Sampling Hold’ mode.
Measures while the signal is ON and establishes the measured value at the rising edge in ‘Peak Hold’, ‘Valley
(Bottom) Hold’ and ‘Peak-to-Peak Hold’ modes.
S-TMR signal: No measuring for the preset ‘Startup Timer’ period from the falling edge in all modes.
HOLD signal: Holds data value at the falling edge of the signal, in ‘Normal’ mode.
Holds TIMING signal status at the falling edge of the signal, in all other modes.
RESET signal: Resets measured value in all modes.
Resets MAX/MIN values and alarm status.
ZERO signal: Enables Forced zero in all modes.
Forced zero lockout setting is disregarded.

• Note for Event trigger mode
HOLD signal is ineffective when RESET signal is ON.
During no-measuring period, displaying maximum or minimum value with MAX/MIN button is not available.
Except in Normal mode, one-shot alarm outputs for each measuring regardless of refreshing rate.
RESET signal does not affect the reference point measured by Forced Zero function.
• ON timing delay/OFF timing delay
Delays logical switching of the Timing signal for the preset delay time from the physical signal change.
When another TIMING signal turns on during ON timing delay period, the previous TIMING signal is canceled.
When another TIMING signal turns on during OFF timing delay period, the previous TIMING signal is canceled.
Set ‘ON timing delay’ time shorter than the period when TIMING signal is ON.
[Example] ON timing delay is 5 sec.

When S-TMR signal turns on within the period of ON/OFF timing delay, thus halts counting time of ON/OFF timing delay
during ‘Startup Timer’ period.
