Megger 659600 Cable Height Meter, 6-Line Separation, 50' Maximum Range

The CHM Series of Cable Height Meters utilize ultrasonic techniques to determine the height of up to six overhead cables and wires. The instruments are designed to address specific measuring requirements on cables up to 75 feet (23 m). The CHM600 (C/N 659600) are designed primarily for power cable applications. The cable height meters emit short bursts of sound which originate from the cone shaped transmitter. The microprocessor in the instruments calculates the elapsed time for the bursts of sound to be reflected from the cable back to the instruments. 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 degrees Celsius. A temperature sensor, mounted at the front of the instru-ments, 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. Ease-of-use - simple, three button operation ensures fast, effective measurements with a minimum of operator training. Compact size - its light weight and hand-held portabil-ity allows easy transport and multiple measurements. Inherently safe - No physical connection to cables. Battery condition indicator - shows the battery warning symbol when the battery voltage falls to approximately 6 volts. Automatic power off - conserves battery power when idle after three minutes. Accuracy: typically less than 0. 5 percent error +/-2 digits. Power source: 9 volt alkaline leak-proof battery (included). Operating Temperature: 14 degrees fahrenheit to 104 degrees fahrenheit (-10 degrees fahrenheit to 40 degrees fahrenheit) with compensation over the full range. Storage: store in dry area. Do not expose to extreme temperature. Use only leak proof batteries. Battery Life: > 50,000 Measurements.
