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. -

1/0.1 mV/A 2113.35 (910 mm) (290 mm) All AmpFlex models are designed to be used with recorders or power analyzers ® with a voltage AC input. A scale factor may need to be entered into the recorder to display the exact value. -
Page 11: Operation
Connect the electronic module to the AC Volt range of your Digital Multi-Meter ■ (DMM) or measuring instrument. Select the appropriate module output voltage range. If the current magnitude is unknown, and if AmpFlex has two ranges, ® select the lowest mV/A output setting. -

■ ® (see figure 2). ■ 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 ■ 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 250 Aac).
