SKU: PLM Category:


The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts peak to peak (range 1999.9 mVp-p, resolution 0.1 mVp-p) in the frequency range 10 KHz – 10 MHz (the frequency limits at which sensitivity is ½ of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).


Operating Voltage:
85 – 300 VAC 50/60 Hz.

Voltage Reading:
85-250 VAC; Accuracy +/- 1 VAC

Line Noise Range:
0.1-1999.9 mVp-p AC (differential)

Line Noise Accuracy:
+/- 8% @ 20 KHz TO 2 MHz; within a factor of 2 from 10 kHz to 10 MHz

5.2 x 3.6 x 1.6 inches; 132 x 91 x 41 mm

8 oz

Power Cable:
Detachable 2-wire cord (ships with North American – 125V)
