Maximum value/minimum value hold (MAX/MIN HOLD)
Functions Detects maximum and minimum measured values (except integration, integration
elapsed time, and time average values) as well as maximum and minimum values for
the voltage and current waveform peak and holds them on the display.
For data with polarity, display of the maximum value and minimum value for the data’s
absolute values is held (so that both positive and negative polarity values are shown).
Peak exceeded and other warning lamps will still light up.
Internal calculations (including integration and integration elapsed time) will continue.
Analog output and waveform output are not held.
Operation Clearing and start of maximum value/minimum value detection
1. Internal data is cleared and detection restarts after zero-adjustment operation is
complete (when turning on the instrument or after zero-adjustment operation).
2. Internal data is cleared and detection restarts when the DATA RESET key is
pressed (including via external control).
3. Internal data is cleared and detection restarts when integration is started.
4. Detection restarts when settings related to measured values are changed, includ-
ing wiring mode and range.
Changing the display
Pressing the MAX/MIN key cycles the display as follows: Maximum value
→
mini-
mum value
→
instantaneous value (causing the MAX and MIN lamp to light up as
appropriate).
Backup Yes (detection restarts when the instrument is turned back on)
