CHAPTER 2 PRODUCT FEATURES Description The MiniFlex HF is a compact flexible AC current transformer composed ® of a flexible sensor and an electronic module. It is designed to measure from 5Hz to 1MHz. The flexible sensor permits measurements on conduc- tors 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 HF is lightweight. It does not use magnetic cores like stan- ®...
Features • Measures from 0.5Arms to 300Arms • Accuracy 1% of Reading ± 0.3A • TRMS measurements when connected to a TRMS instrument • No core saturation or damage if overloaded • 9V battery for typical 140 hour continuous operation • 1MHz frequency response • Low phase shift for power measurements • Insensitive to DC, measures only AC component on DC + AC signals •...

CHAPTER 4 OPERATION Compatibility The MiniFlex is compatible with any Oscilloscope, AC voltmeter, or other ® voltage measuring instrument with an input impedance greater than 1MW. To achieve the best overall accuracy, use the MiniFlex with an Oscillo- ® scope set to AC mode with an accuracy of 0.75% or better Tips for Making Precise Measurements • When using the MiniFlex with an Oscilloscope, it is important to ®...
Making Measurements • Connect the electronic module to the AC Volt range of a Oscilloscope input or measuring instrument. Select the highest range on the Mini- Flex ® • 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. • Read the displayed value on the Oscilloscope and divide it by the range selected (i.e. if reading = 2.59V with the 10mV/A output range, the cur- rent flowing through the probe is 2590mV ÷ 10 = 259A).
CHAPTER 5 MAINTENANCE 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 cir- cuits before opening the case. 5.1.1 Battery Replacement The battery must be replaced when the green indicator flashes or remains off when the instrument is switched on.
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). Ship To: Chauvin Arnoux , Inc. d.b.a.
