ALWAYS de-energize the circuit before wrapping the FlexProbe®
around bare conductors, bus bars, or near live parts. Do not wrap on
live conductors.
ALWAYS connect the electronic module to the display device before
wrapping the FlexProbe® around the sample being tested.
ALWAYS inspect the module, sensor, sensor cable, and output termi-
nals prior to use. Replace any defective parts immediately. Use only
factory parts.
NEVER use the FlexProbe® on electrical conductors rated above
1000V CAT III and 600V CAT IV.

the electrical distribution system. Examples are measurements
on household appliances or portable tools.
CAT III: For measurements performed in the building installation at
installation and circuit breakers.
CAT IV: For measurements performed at the primary electrical supply
(<1000V) such as on primary overcurrent protection devices,
ripple control units, or meters.

ments on conductors where standard clamp-on probes could not be
used. In particular, it can be installed in tight spaces, around breaker
panels, around cable bundles, around wide or large bus bars, or even
wrapped around irregular shapes.
The Shape Memory feature enables the user to “pre-shape” the sensor
before inserting it between or around conductors. This feature facilitates
The FlexProbe
®
is lightweight. It does not use magnetic cores like standard
transformers. The transformation principle is based on an air core. It
presents virtually no load to the system under test, has a low phase shift
and excellent frequency response, and cannot be damaged by overloads.
The sensor assembly is waterproof and insulated for 1000V CAT III;
600V CAT IV. The FlexProbe® meets EN 61010-1 and is CE marked.
The FlexProbe® has a mV output proportional to the current measured
for direct readings on DMMs, data loggers, oscilloscopes, and power or
harmonic meters. TRMS measurements are taken when connected to a
TRMS meter. The FlexProbe
®
is insensitive to DC currents and only the AC
component of the measured signal is measured. The sensor length is 24".

Please make sure that you have already read and fully understand the
WARNING section on page 1.
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.
300A range to obtain the best resolution, if the reading is less than
300mV.
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
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® is connected
to a True RMS meter. Note that the DC component is not measured.

• When using the FlexProbe® with a meter, it is
important to select the range that provides the
best resolution. Failure to do this may result in
measurement errors.
• For best results, select the highest FlexProbe®
output signal possible and the most sensitive
meter range for this output.
• Make sure the DMM or measuring instrument can
accurately measure mVAC. Certain inexpensive
DMM have poor resolution and accuracy when
measuring low mVAC.
• For best accuracy, center the FlexProbe® around
the conductor to be measured.
• To increase the sensitivity or measure on low cur-
rents, the FlexProbe® may be wrapped several
times around the conductor. Remember to divide
your reading by the number of turns for the actual
measurement (See Figure 1).
• The overall measurement accuracy is the sum of
the FlexProbe®accuracy and the displaying instru-
ment accuracy.
• The FlexProbe® may be doubled around the con-
ductor to be measured to double the output. (See
DMM while measuring 250AAC.)

• To avoid electrical shock, do not attempt to perform any servicing
• Do not perform any service while the FlexProbe® is on any
circuit.
• To avoid electrical shock and/or damage to the instrument, do
not get water or other foreign agents into the electronic module.
• Also see warning on page 1.
If the power ON indicator (green LED) blinks or does not light up, replace
the battery.
Disconnect the instrument from any source of electricity.
• To replace the battery, open rear case, replace battery and
re-assemble.
• The green LED should go on when the module is turned on.
• Use a soft cloth lightly dampened with soapy water, then dry with
a dry cloth.
• Do not splash water directly on the instrument.
• Do not use alcohol, solvents or hydrocarbons.
• Make sure the sensor, electronic module, and all leads are dry
before any further use.
