Datasheet of I800 - CURRENT CLAMP PROBE AC

Wire size and the position of the wire within the probe

jaws does not affect measurement accuracy.

Multimeter readings displayed in milliamps (mA) can be

read directly as amperes of conductor current. Readings

displayed in amperes (A) must be multiplied times 1000

to obtain the amperes of conductor current.

Meter Readings

When the Clamp is connected to a compatible current meter and

clamped around a single current-carrying conductor, the meter

reading will be one 1000th of the actual current in the conductor.

For example, a 5 A input current will be transformed into a 5 mA

output current (see Figure 1). When measuring current in an ac

line cord, the jaws should be clamped around only one conductor

(the black or hot wire in a three wire cord). If the jaws are

clamped around both current carrying conductors, the currents

will cancel and produce a zero reading. If the probe is clamped

around two wires carrying current in the same direction, the sum

will be read. Reversing one of the wires causes the difference to
