Caywood Electronics / Millen Power Line Noise Detector Type 71001

Condition:  USED
      Please see all pictures for condition.

A portable test instrument, formerly manufactured by Millen, for detecting power line noise interference and verifying when the problem has been corrected has recently been introduced by Caywood Electronics, Inc. The Millen Type 71001 Power Line Noise Interference Detector is a passive, portable test instrument that helps determine if EMI/ RFI noise problems are coming in on the ac or dc power line, or being generated by some device on the line. Used with an oscilloscope or panel-meter equipped radio receiver, it can also be used to confirm that the noise problem has been corrected. Sensitive only to EMI/RFI noise on power lines, the 8 in. H x 6 in. W x 11 in. L, 11 lb. Millen Type 71001 Power Line Noise Interference Detector incorporates a damped filter that rings slightly allowing pulses to show up on a narrow band oscilloscope. The sensing elements in the filter are not traversed directly by line current, and are immune to saturation effects that could distort results.
