5.3 Data Hold and Peak Hold Functions
96
When the interval timer is used, the maximum value within each interval is displayed.
When the timer or clock control is enabled, the maximum value between starting and stopping times is
displayed (and held).
• Waveform displays and integration values are unaffected by Peak Hold.
• When averaging is enabled, the maximum value is recognized only after measured values
have been averaged.
• Data Hold and Peak Hold functions cannot be activated simultaneously.
• The display shows [- - - - - -] for over-range values. In this case, temporarily cancel Peak
Hold and switch to the appropriate range.
• Maximum values for Peak Hold are absolute values, so if -60 W is measured after +50 W, the
absolute value of -60 W is larger, and the display shows [-60W].
• Settings cannot be changed while Peak Hold is active.
• When auto-saving at a specified interval, data is saved immediately before the display update.

• The Peak Hold function can be enabled either before or during timing control operation. How-
ever, when timing control is active, the maximum value is obtained only after the time the
Peak Hold function is enabled.
• The time of maximum input occurrence is not displayed.
• See "5.1 Timing Control Functions" (p. 91) for details about settings for the interval, timer
and clock timing controls.
