Page 6: Description
® AmpFlex - Flexible AC Current Probes Description ® The AmpFlex is a 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 tight spaces, around breaker panels, around cable bundles, around wide or large bus bars, or even wrapped around irregular shapes. - Page 7 ® AmpFlex - Flexible AC Current Probes ® AmpFlex Figure 1 1.

Page 14: Instrument Compatibility
® AmpFlex - Flexible AC Current Probes Instrument Compatibility ® The AmpFlex is compatible with any multimeter, AC voltmeter, or other voltage measuring instrument with an input impedance greater ® than 1M. To achieve the best overall accuracy, use the AmpFlex with a AC voltmeter having an accuracy of 0.75% or better. - Page 15 ® AmpFlex - Flexible AC Current Probes Tips for Making Precise Measurements (continued): To increase the sensitivity or measure on low currents, the AmpFlex ® may be wrapped several times around the conductor. Remember to divide your reading by the number of turns for the actual measurement (see Figure 4).
- Page 16 ® AmpFlex - Flexible AC Current Probes Tips for Making Precise Measurements (continued): ® The AmpFlex may be doubled around the conductor to be measured to double the output. (See Figures 3 and 4 to show the different values on a DMM while measuring 250A 250 A C O M...
