Making Measurements
• Connect the electronic module to the AC Volt range of a multimeter or
measuring instrument. Select the highest range on the MiniFlex
®
.

V
• Press the sensor’s yellow opening device to open the flexible coil.
• Wrap the coil around the conductor to be tested. If possible, within
range, select the lowest range to obtain the best resolution.
• Do not exceed specified current range for the output. Do not use on
selected range if overload LED goes on.
• Read the displayed value on the multimeter and divide it by the range
selected (i.e. if reading = 2.59V with the 10mV/A output range, the cur-
rent flowing through the probe is 2590mV ÷ 10 = 259A).
• For best accuracy, carefully center the conductor inside the flexible
core, and if possible, avoid being in the proximity of other conductors
which may create noise and interference (particularly near the latch).
• True RMS measurements are obtained when the MiniFlex
®
is connected
to a True RMS meter. Note that the DC component is not measured.
