The Megger CHM600 (659600) Cable Height Meter utilizes ultrasonic sound to determine the height of up to six overhead cables and wires. The instrument is designed to address specific measuring requirements on cables up to 50 feet (15 m). The CHM600 is designed primarily for power cable applications.

The CHM600 Cable Height Meter emits short bursts of sound which originate from the cone shaped transmitter. The microprocessor in the instrument calculates the elapsed time for the bursts of sound to be reflected from the cable back to the instrument. The result can be displayed in either feet and inches or meters. However, before the final measurement can be displayed, the air temperature must be measured because the speed of sound varies at approximately 0.2 percent per degree Celsius.

A temperature sensor, mounted at the front of the instrument, senses the actual air temperature. This information is sent to the microprocessor and incorporated into the algorithm. The distance is then displayed in meters or feet and inches depending on which was selected.
