Operation
■
For maximum measuring accuracy, position the
cable as accurately as possible between the
clamp jaws [1] .

If the cable is inaccurately positioned within the
plier jaws, the measurement error is no more than
1.5 %.
Accuracy:
±
(% of the r number of digits) at 18° to
28 °C (64° to 74 °F) and rel. humidity < 75 %.
