The current probes and flexible sensors are used to measure the current flowing
in a conductor or bus bar without opening the circuit. They also insulate the user
from dangerous voltages in the circuit.
The choice of current probe or sensor to be used depends on the amperage to be
measured and the diameter of the cables or size of the bus bar.
■ For three-phase measurements, use the color-coded ID markers to associate
a color for each current input to match the phase identifiers on the measured
system.
IMPORTANT NOTE:
with the indicating arrows pointing toward the load.
For Example Only (instrument's will vary):
■ Connect the current probe or sensor to the current terminals of the instrument.
For MR193 and SL261 Probes:
■ MR193: Set the switch to 1mV/A; the ON indicator will light up.
SL261: Set the switch to 10mA or 100mA/A; the ON indicator will light up.
■ Connect the probe to the instrument.
■ Adjust the zero by turning the potentiometer with no conductor in the jaws of the
clamp.
■ When the measurement is finished, turn the probe switch to OFF.
