③Take the reading on the display.
NOTE
● During current measurement, keep the transformer jaws fully
closed. Otherwise, accurate measurement cannot be made. The
maximum measurable conductor size is 54.5mm in diameter.
● When measuring a larger current, the transformer jaws may buzz.
This is not a fault and does not affect the accuracy at all.

①Set the function selector switch to the "〜400A" or "〜2000A" position.
②Press the mode switch to select the peak mode. "PEAK" will be
shown on the display.
③Press the trigger to open the transformer jaws and clamp them onto
the conductor under test. Then, press the reset switch.
④The display shows the current's crest value divided by the square
root of two. Therefore, when the current is sinusoidal, the reading
equals RMS value.
⑤To reset the display, press the reset switch.
（Note: When this is done, the reading goes off for about one second.）
⑥After the measurement is over, press the mode switch to return to
the normal mode.
NOTE
●In the peak measurement mode, the data hold feature is disabled.
●When a measured value is 9 counts or less, it is corrected to 0 (KEW
SNAP 2002R).
