PRODUCT FEATURES

2.1 Description

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.

OPERATION

4.1 Compatibility

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.

.
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.

MAINTENANCE

Warning
For maintenance use only specified replacement parts.To avoid electrical shock, do not attempt to perform any servicing
unless you are qualified to do so.
To avoid electrical shock and/or damage to the instrument, do not get
water or other foreign agents into the case.
Turn the instrument OFF and disconnect the unit from all the circuits
before opening the case.
5.1.1
The battery must be replaced when the green indicator flashes or remains off when the instrument is switched on.
Disconnect everything connected to the instrument and set the

Cleaning
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).
