n Peak-to-peak Hold
In Peak-to-peak Hold Mode, measurements are performed while the timing
input is ON, and the difference between the maximum value and the mini-
mum value in the sampling period will be the output value.
Hold Mode starts when the power is turned ON, immediately after chang-
ing to RUN or T Mode, or immediately after the reset input is turned OFF.
The output is held at the maximum output (current: approximately 23 mA,
voltage: approximately 5.5 V) until the first sampling period is finished. The
first measured result (P
the first sampling period to the end of the second sampling period. After
the second sampling period, the second measured result (P
figure below) is output and the sequence is repeated.
