CHAPTER 2 PRODUCT FEATURES 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. The MiniFlex is lightweight. It does not use magnetic cores like standard ® transformers. The transformation principle is based on an air core. It pres- ents 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 insulated for 1000V CAT III; 600V CAT IV. The Mini- Flex meets EN 61010 and is CE marked. ® The MiniFlex has an mV output proportional to the current measured ®... -

Page 17: Operation
CHAPTER 4 OPERATION Compatibility The MiniFlex is compatible with any multimeter, 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 AC voltme- ® ter having an accuracy of 0.75% or better. 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 in measurement errors. -
Page 18: Making Measurements
Making Measurements • 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 cur- rent flowing through the probe is 2590mV ÷ 10 = 259A). -
Page 19: Maintenance
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. • Disconnect everything connected to the instrument and set the switch to OFF. • Use a screwdriver to unscrew the two screws on the housing. • Replace the old battery with a new one (9V alkaline or lithium bat- tery of type 6LF22). • Close the housing, making sure that it is completely and correctly closed, then screw both screws back in. 5.1.2 Cleaning •... - Page 20 DataLoggerStore 1.800.561.81 www.
