How do I make measurements with the MiniFlex®?
- Connect the electronic module to the AC Volt range of a multimeter or measuring instrument. Select the highest range on the MiniFlex®.
- 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 current 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.

- Replace the old battery with a new one (9V alkaline or lithium battery of type 6LF22).
- Close the housing, making sure that it is completely and correctly closed, then screw both screws back in.
What should be kept clean on the sensor? It is important to keep the sensor latch mating surfaces clean to prevent foreign matter from entering the closing.
How should the sensor be cleaned? The sensor may be gently cleaned with a soft cloth, soap, and water. Dry immediately after cleaning. Avoid water penetration into the electronic module.
