Set the hold conditions of the measured value.
The hold function holds (retain) any value from the measured values during the specific time (sampling period), such as the maximum or minimum value.
Setting the Hold Mode
Set the hold mode of the measured value.
Item Setting item Setting value Description
Hold Hold mode Peak Holds the "maximum value" of the sampling period. Output changes after sampling, and this state is held until the next sampling ends.
Bottom Holds the "minimum value" of the sampling period. Output changes after sampling, and this state is held until the next sampling ends.
Peak to Peak Holds the "difference between the maximum value and the minimum value" of the sampling period. Mainly select this when detecting vibration, for example.
Output changes after sampling, and this state is held until the next sampling ends.
Auto Peak Holds the "maximum value" of the measurement result. The output changes every time the maximum value is updated.
Auto Bottom Holds the "minimum value" of the measurement result. The output changes every time the minimum value is updated.

Holds the difference between the maximum and minimum values of the measurement result. The output changes every time the maximum or the minimum value is updated.
Average Holds the "average of the measured value" of the sampling period. Output changes after sampling, and this state is held until the next sampling ends.
Sampling Holds the measured value the moment that control enters the sampling period. Output changes at the start of sampling, and this state is held until the next sampling is started.

The hold function is not used. The measured value is always output.

Hold clearing conditions
Held values can be cleared by the following operation.
• When FUN (adjustment) mode/RUN (operation) mode is switched
• When hold RESET is entered (32-pole extension connector, key)
• Hold RESET command is entered.
(Example) Peak
(Example) Auto Peak
If an abnormal measured value is obtained during sampling, the hold value is cleared. To not clear the hold value even if an abnormal measured value is obtained, set "KEEP" as the non-measurement setting.
Setting operation when measurement is not possible p.148
When the hold value is reset, the clamp level is output until the next hold value is applied.
The mode is switched between the FUN mode and RUN mode

Set-tings
Trigger method External input Enter the trigger for the start of sampling in "TIMING input" for the 32-pole terminal block.
The period that the signal input to "TIMING input" is ON is the sampling period.
When a delay time is set, input OFF and sampling period end are not synchronized. End timing is after the specified sampling period has elapsed.
Selfup trigger The period in which the measured value exceeds the preset self-trigger level is taken to be the sampling period.
Hold measurement can be performed without a synchronous input.
When a delay time is set, the timing that the measured value falls below the self-trigger level and the sampling period end are not synchronized. End timing is after the sampling period has elapsed.
Selfdown trigger The period in which the measured value falls below the preset self-trigger level is taken to be the sampling period.
Hold measurement can be performed without a synchronous input.
When a delay time is set, the timing that the measured value exceeds the self-trigger level and the sampling period end are not synchronized. End timing is after the sampling period has elapsed.
