EX65x Series True RMS

600A Clamp Meters

Choice of AC Current (EX650) or fully loaded advanced

AC/DC Current (EX655) model. Both meters feature

True RMS providing accurate readings when measuring

distorted or noisy waveforms and Low Impedance

(LoZ) mode to eliminate false readings caused by ghost

voltages. EX655 also features Low pass ﬁlter (LPF)

which attenuates high frequencies to reduce noise for

accurate readings and Inrush mode to capture current

surges during motor startup.

Common Features

• True RMS for accurate AC measurements

• 1.18" (30mm) jaw size accommodates conductors up

to 350MCM

• LoZ prevents false readings caused by ghost voltages

• µA function for HVAC ﬂame rod Current measurements

• Built-in Non-contact AC Voltage Detector (NCV)

with LED indicator

• 6000 count backlit LCD display

• Data Hold freezes the reading on the display

• Min/Max captures highest and lowest readings

• Relative function

• Convenient LED worklight for viewing in dimly lit area

• Auto Power Off conserves battery life

Model Features

• Model EX650

- 9 Functions including AC Current
