2.2 Current Measurement
_______________________________________________________
NOTE
MAX AVE MIN Instantaneous value
(no annunciator)
The polarity of the input is not displayed during
peak measurements. The measured values may
change if the clamp sensor is reoriented, but the
values are within the guaranteed accuracy.
You can capture from pulses with a width of about
more than 1ms.
Even after clamping, press
0ADJ/RESET button to
reset the data as necessary.
In case that the counter doesn't become zero under
no input in peak measurement mode, even though
you pressed
0ADJ/RESET
button to reset the peak
data, the clamp sensor may be magnetized. Quit the
peak measurement mode, and perform the auto-zero
adjustment by
0ADJ/RESET button . Then make
the settings again. (A few counts would remain,even
if you push
0ADJ/RESET button .)
The hold value does not change, unless a larger
value is measured, but be careful to avoid accidental
loss of data resulting from the auto power-off
function. (See 3.5: Automatically Turning Power
off (Auto Power-Off Function APS))
Use the REC function to make measurements longer
than the auto power OFF time.
To check transitional peak value, press
MAX/MIN
button to shift to the instantaneous value (no
annunciator).
