CAT II: For measurements performed on circuits directly connected to the
electrical distribution system. Examples are measurements on household
appliances or portable tools.
CAT III: For measurements performed in the building installation at the
distribution level such as on hardwired equipment in fixed 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.
Upon receiving your shipment, make sure that the contents are consistent
with the packing list. Notify your distributor of any missing items. If the
equipment appears to be damaged, file a claim immediately with the carrier and notify your distributor at once, giving a detailed description of any
damage. Save the damaged packing container to substantiate your claim.

Model 3000-24-1-1 .................................................. Cat. #2132.63
The MiniFlex® is a compact flexible AC current transformer composed of a
flexible sensor and an electronic module. The flexible sensor permits
measurements on conductors where standard clamp-on probes could not be
used. In particular, it can be installed in confined spaces, places where
access is difficult, or even wrapped around irregular shapes.

The MiniFlex® is compatible with any multimeter, AC voltmeter, or other
voltage measuring instrument with an input impedance greater than 1MΩ. To
achieve the best overall accuracy, use the MiniFlex
having an accuracy of 0.75% or better.
4.2 Tips for Making Precise Measurements
When using the MiniFlex® with a meter, it is important to select the range that
provides the best resolution. Failure to do this may result i n measurement
errors.
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 MiniFlex
measured.
The overall measurement accuracy is the sum of the MiniFlex
the displaying instrument accuracy.
1. Connect the electronic module to the AC Volt range of a multimeter or
measuring instrument. Select the highest range on the MiniFlex
COM
+
®
.
2. Press the sensor’s yellow opening device to open the flexible coil.
3. Wrap the coil around the conductor to be tested. If possible, within
range, select the lowest range to obtain the best resolution.
4. Do not exc eed specified current range for the output. Do not use on
selected range if overload LED goes on.
5. Read the displayed value on the multimeter and divide it by the range
selected (i.e. if reading = 2.59V with the 1mV/A output range, the current flowing through the probe is 2590mV = 2590A).
6. 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).
®
7. True RMS measurements are obtained when the MiniFlex
is
connected to a True RMS meter. Note that the DC component is not
measured.
It is important to keep the sensor latch mating surfaces clean to
prevent foreign matter from entering the closing.
The sensor may be gently cleaned with a soft cloth, soap and water.
Dry immediately after cleaning. Avoid water penetration into the
electronic module.
Make sure the sensor, electronic module, and all leads are com-
pletely dry before any further use.

Repair and Calibration
To ensure that your instrument meets factory specifications, we recommend
that it be scheduled back to our factory Service Center at one-year intervals
for recalibration, or as required by other standards or internal procedures.
For instrument repair and calibration:
You must contact our Service Center for a Customer Service Authorization
Number (CSA#). This will ensure that when your instrument arrives, it will be
tracked and processed promptly. Please write the CSA# on the outside of the
shipping container. If the instrument is returned for calibration, we need to
know if you want a standard calibration, or a calibration traceable to N.I.S.T.
(Includes calibration certificate plus recorded calibration data).
The MiniFlex® is warranted to the owner for a period of two years from the
date of original purchase against defects in manufacture. This limited warranty
is given by AEMC
chased. This warranty is void if the unit has been tampered with, abused or if
the defect is related to service not performed by AEMC

Warranty Repairs
What you must do to return an Instrument for Warranty Repair:
First, request a Customer Service Authorization Number (CSA#) by phone
or by fax from our Service Department (see address below), then return the
instrument along with the signed CSA Form. Please write the CSA# on the
outside of the shipping container. Return the instrument, postage or shipment
pre-paid to:
Caution: To protect yourself against in-transit loss, we recommend you insure
your returned material.
NOTE: You must obtain a CSA# before returning any instrument.
