Martindale Electric Company, Ltd. CM69 Digital Ammeter

CM69 is a high-performance TRMS AC leakage clamp meter with outst low current capability. The pocket clip also measures AC-DC voltage and resistance. The advanced jaw design minimizes the effects of conductor position and shields external magnetic fields from other conductors,providing more accurate and consistent results. Ground leakage clamps work by clamping the live and neutral conductors. They also measure the difference between the flowing currents,thus showing the leakage value. Alternatively,a clamped ground conductor exhibits ground leakage current. Peak hold. Switchable low pass filter. TRMS measurement. Troubleshooting RCD interference tripping. Periodically measure leakage current at 50 Hz to check for insulation degradation. Accurately measure triple neutral current and other distorted waveforms. Differential current measurements for appliance testing. Automatic ranging. High contrast backlight display Absolute maximum AC current measurement value = 60A ACAbsolute maximum AC voltage measurement value = 600V ACAbsolute maximum DC voltage measurement value = 600V DCAbsolute maximum resistance measurement value = 600kOhms Model digital = CM69AC current measurement resolution = 0.001mABest AC current accuracy = 1 %+8 digits AC voltage accuracy=1%+3 digits; DC voltage accuracy=1%+2 digits; distance measurement resolution=0.1Ohms
