When 0 is displayed after zero adjustment, the measurement
can be performed without the interference of the count
remaining immediately after the power is turned on.
4. Open the top ends of the clamp core, orient the current
direction indicator on the clamp in the current direction of
the measured conductor, and clamp the conductor so that
it passes through the center of the clamp core.
･ The DC A mode permits only DC current
measurements that does not include the AC
component (see 1.5: Modes).
･ The20Arangewilldisplayupto25A,however,
only the range from 1 A to 20 A can be displayed
with guaranteed accuracy.
･ At any range, gross errors may occur at 1% or
below of the range, whose accuracy is not
guaranteed, as a result of internal corrective
calculations.
･ The value may sometimes not show 0 when the
power is switched on, but this is not an instrument
fault. Please execute auto zero adjustment before
measuring.
