3.5.2 Current Waveform Peak Hold Function and Maximum
Value Measurement
NOTE
These enable incoming current transients and maximum value of
measurement items to be measured.
(1) Press the
SHIFT
→
HOLD
keys to start the peak hold function. While the peak
hold function is activated the HOLD indicator flashes.
(2) Press the
SHIFT
→
HOLD
keys again to return to the normal display. (the HOLD
indicator goes off.)
(3) While the peak hold function is activated, pressing the
HOLD
key resets the
peak value to the present instantaneous value.
(4) The peak value of the current waveform is shown as Ip.
(5) While the peak hold function is activated, for other measurement items the
unit shows the maximum value since the peak hold function was activated.
Pressing the
HOLD
key also resets these maximum values to the present
instantaneous values.
･ The displayed peak value or maximum value is not necessarily measurements
at the same time.
･ For all items, the absolute values are compared.
･ When the averaging function is used, the maximum value is taken from the
averaged values, but the peak value is taken from the original values before
averaging.
･ Pressing the
SHIFT
→
HOLD
keys while the hold function is active (HOLD
indicator lit) switches to the peak hold function.
･ Power factor or phase angle "o.r" indications are treated as a power factor of
zero or phase angle of zero. (As minimum values) A frequency "o.r"
indication or "-----" indication is treated as a frequency of 0 Hz. (As
minimum value) For other items, an "o.r" indication is treated as a maximum
value.
･ The integration value is update during peak hold.
