Making Measurements with the FlexProbe

1. Connect the electronic module to the AC Volt range of your DMM or
measuring instrument.
2. Select the appropriate module output voltage range. If the current
magnitude is unknown, select the 3000A range.
3. Wrap the flexible core around the conductor to be tested. Select the
300A range to obtain the best resolution, if the reading is less than
300mV.
Do not exceed specified current range for the output. Do not
use on selected range if Overload LED goes on.
4. Example:
a. Read the DMM displayed value: 2.59V
b. Determine the range and output used on the FlexProbe: 0.01V/A
for the 300A range; .001V/A for the 3000A range
c. Divide the reading by the output to determine the actual current
value: 2.59 ÷ 0.01 = 259A or 2.59 ÷ 0.001 = 2590A
For best accuracy, carefully center the conductor inside the flexible core,
and avoid if possible, the proximity of other conductors which may create
noise and interference (particularly near the latch).
True RMS measurements are obtained when the FlexProbe
to a True RMS meter. Note that the DC component is not measured.
