AC Current
(
AC A
)
･ The DC A mode permits only DC current
measurements that does not include the AC
component (see 1.5: Modes).
･ The 200 A range will display up to 250 A, however,
only the range from 10 A to 200 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.
1. Press
to display .
2. Switch between the auto range and the manual range
as necessary.
3. Open the top ends of the clamp core and clamp the
measured conductor so that it passes through the
center of the clamp core.
･ Just after suspension of input, or when modes are
switched under no input, the counter would not
become zero for about 10 seconds. This is normal
and simply reflects the workings of the internal
circuit. But you can measure with guaranteed
accuracy before the counter becomes zero.
