■ Hold Functions
The hold functions extract, output, and display data for specific
points, such as the maximum value, the minimum value, etc.
There are six hold functions: Peak hold, bottom hold, sample
hold, peak-to-peak hold, self-peak hold, and self-bottom hold.
Normal Mode (Hold Not Enabled)
In Normal Mode, the measured value is always displayed and out-
put. The timing input is disabled and no hold function will operate.
Peak Hold
In Peak Hold Mode, measurements are performed while the tim-
ing input is ON, and the maximum value during the sampling
period will be the output value.
Hold Mode starts when the power is turned ON, immediately after
changing 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 (A in the figure below)
is output from the end of the first sampling period to the end of the
second sampling period. After the second sampling period, the
second measured result (B in the figure below) is output and the
sequence is repeated.
Bottom Hold
In Bottom Hold Mode, measurements are performed while the
timing input is ON, and the minimum value during the sampling
period will be the output value.
Hold Mode starts when the power is turned ON, immediately after
changing 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 (A in the figure below)
is output from the end of the first sampling period to the end of the
second sampling period. After the second sampling period, the
second measured result (B in the figure below) is output and the
sequence is repeated.
Sample hold
In Sample Hold Mode, the measured result when the timing input
is turned ON will be the output value.
Hold Mode starts when the power is turned ON, immediately after
changing 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 time the timing
input turns ON. The first measured result (A in the figure below) is
output from the beginning of the first sampling period to the sec-
ond sampling period. After the beginning of the second sampling
period, the second measured result (B in the figure below) is out-
put and the sequence is repeated.
