AC/DC clamp current sensor with voltage output for multimeter, 30/300A, 25mm Ø. The CP30, CP330, CP1100 and CP1800 clamp current sensors were developed for precise, contactless 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 the Hall effect sensors a powerful instrument for measuring converters, switched-mode power supplies, industrial controls and other applications that require current measurement or analysis of the signal form. AC and DC current measurement for TRMS multimeters High accuracy 1% 50 mA / 100 mA resolution Automatic switch-off to save battery High bandwidth DC..20 kHz The transmission factors can be set directly in the METRAHIT multimeters Simple zero adjustment at the touch of a button TYPE CP330 Measuring range 0 ...30 / 300 A Resolution 50 / 100 mA Overcurrent capability 600 A (60s) Gain drift /°C ±0.1 % of MW Transfer factor 10 / 1 mV/A General DC accuracy ±1% of MW ±50/100 mA Frequency range DC to 20 kHz (-3 dB) Clamp opening 25 mm Article number Z202B . 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
