2. PRODUCT FEATURES 2.1 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. -

3. OPERATION Please ensure that you have already read and fully understand the Precautions for Use section on page 6. 3.1 MAKING MEASUREMENTS WITH THE AMPFLEX ® ■ Connect the electronic module to the AC Volt range of your Digital Multi-Meter (DMM) or measuring instrument. - Page 12 TIPS FOR MAKING PRECISE MEASUREMENTS (CONTINUED) ■ To increase sensitivity or measure on low currents, the AmpFlex may be ® wrapped several times around the conductor. Divide your reading by the number of turns for the actual measurement (see Figure 4). ■...
- Page 13 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 250Aac). One turn around a conductor carrying 250Aac. Figure 3 AmpFlex Current Probe...
