Bottom hold
•
The minimum value is held while measurement is being performed
(while the TIMING input is ON) and when the measurement has
been completed (when the TIMING input turns OFF) the
measurement value is refreshed using the smallest held value.
Important *
• When the measurement value exceeds the measurement range
during measurement, a sensor error will occur, a sensor error will
immediately show on the display, and all outputs will turn OFF.
Also, the measurement at that time will be invalid.
• Measurements are not performed during RESET input and
TIMING inputs are disabled.
The PV display will show "-----" in no measurement status.
Selecting operations for input errors. → P.5-23
If the operation at input error is set to OFF (disabled) or OVER (overflow),
operations will continue.
Peak-to-peak hold
• The maximum and minimum values are held while measurement
is being performed (while the TIMING input is ON). When the
measurement has been completed (when the TIMING input turns
OFF), the measurement value is refreshed using the maximum
value minus the minimum value (i.e., the peak-to-peak value).
Important *
• When the maximum or minimum value exceeds the measurement
range during measurement, a sensor error will occur, a sensor
error will immediately show on the display, and all outputs will turn
OFF. Also, the measurement at that time will be invalid.
• Measurements are not performed and TIMING inputs are disabled
during RESET input.
The PV display will show "-----" in no measurement status.
Selecting operations for input errors. → P.5-23
If the operation at input error is set to OFF (disabled) or OVER (overflow),
operations will continue.

Input error
Measurement invalid because a sensor
error occurred during measurement.
Measurements during
reset input are invalid.
Measurement
range lower limit
A sensor error occurs and all outputs are turned OFF
if the measurement range is exceeded.
Remarks
* If the operation at input error (s.err) is set to OFF, the measurement value will be displayed as
the upper or lower limit of the display range if it exceeds the measurement range, and a sensor
error will occur. If this happens, the comparative result will not be based on the real measurement
value. The display flashes when TIMING is set to OFF in peak hold, bottom hold, and peak-to-
peak hold, and the comparative output is based on the display value.
