AC/DC clamp current sensor with voltage output for multimeter, 1800A, 32mm Ø. The clamp current sensors CP30, CP330, CP1100 and CP1800 were developed for precise, non-contact measurement of AC and DC currents as well as complex current signal forms (TRMS). Using the latest Hall effect technology, they are suitable for precise current measurement. Their properties make Hall effect sensors a powerful instrument for measuring converters, switch-mode power supplies, industrial controls and other applications that require current measurement or signal shape analysis. AC and DC current measurement for TRMS multimetersHigh accuracy 1%100 mA / 500 mA resolutionAutomatic switch-off to save batteryHigh bandwidth DC..20 kHzThe transfer factors can be set directly in the METRAHIT multimetersSimple zero adjustment at the touch of a button TYPE CP1800 Measuring range 0..125 / 1250 A Resolution 100 / 500 mA Overcurrent capability 2000 A (60s) Gain drift /°C ±0.1% of MW Transfer factor 10 / 1mV/A General DC accuracy ±1% of MW MW ±100/500 mA Frequency range DC to 20 kHz (-1 dB) Clamp opening 32 mm Article number Z204A . Power saving circuit: The device switches off automatically after approx. 10 minutes if no button has been pressed during this time. The switch-off can be cancelled. 1 AC / DC current sensor1 9 V alkaline battery1 Operating instructions
