659600

659600 is a CHM series cable height meter. It utilizes ultrasonic techniques to determine the height of up to six overhead cables and wires. It is designed primarily for power cable applications. It emits 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 degree Celsius. The application includes measuring cable heights telephone lines, distribution lines, transmission lines, cable television, street lights, sag, and separation between up to six cables.

• Compact size, light weight and hand-held portability allows easy transport and multiple measurements
• Inherently safe no physical connection to cables or wires required to obtain measurement
• Shows the battery warning symbol when the battery voltage falls to approximately 6V
• Automatic power off conserves battery power when idle after three minutes
• Ease-of-use, calibration and maintenance free operation minimal down time
• Pre-selectable measuring modes will read in either meters or feet and inches for universal use
• Six cable measurement capability handles almost any field application
• Quicker measurement of cable height saves time and money
• 3m to 15m (10ft to 50ft) measuring range, 9V battery type
• Typically less than 0.5% error ±2 digits accuracy, operating temperature range from -10 to 40°C
