Feature:1. Clampon current probe, the range supports 100mV/A and 10mV/A, with small error.2. No need to disconnect the circuit, bid farewell to tedious circuit frequency measurement, and make the measurement easier.3. The current clamp can be used with any test instrument with BNC interface and impedance of 1M and <100pF.4. Easy to install and use, stable performance, high measurement accuracy, it is a practical electrical equipment.5. This current clamp has an autozeroing position so that it can be used in different environments.Specification:Item Type: Clip-On Current ProbeMaterial: ABSLength: Approx. 230mm / 9.1inRange100mV/A10mV/ACurrent Range50mA-10A peak10A-100A PeakPercent Error of Output Signal3%5mV500m-10A Peak Value: 4%500uV10-100A Peak Value: 15% Maximum At 100AFrequency Range (-3dB)DC-100KHZPhase ShiftDC-65HZ: <1.5DC-65HZ: <1Load Impedance1M and 100PFInsertion Impedance0.01Noise6mV600uVConversion Rate0.3V/uS20mV/USRise/Fall Time3uS<4uSMeasurement Condition235, 20-75%RH, sinusoidal frequency 48-65HZ, external magnetic field <40A/m, no current-carrying wire nearby, center test sample, load impedance 1MPower Supply1X6F22 9V alkaline dry battery (not included)Low Battery IndicatorWhen >6.5V, the LED is greenOverload IndicationThe red LED indicates that the measurement current is too large and the range needs to be changedMaximum Insertion in JawDiameter 11.8mm / 0.5inOutput2m coaxial cable, terminal with insulated BNC socketOperating Temperature0-50Storage Humidity -3-80Operating Relative Humidity10-30: 855% relative humidity (non-condensing)40-50: 455% Relative Humidity (Non-Condensing)Operating Height0-2000m / 0-6561.7ftHow to Use:1. Install the battery (this product does not have a battery) to start the current test clamp, and move the switch to the 100mV/A gear.2. Check that the battery green indicator is on (ON is on, OL is off).3. Connect the current clamp to the oscilloscope.4. When the current clamp is closed, but the wire is not clamped. Select the highest sensitivity on the oscilloscope (for example, 1mV/cm, current clamp to select 100mV/A).5. When the current clamp is closed and there is no conductor, select the highest sensitivity on the oscilloscope and the current clamp (for example: 1mV/cm) and then turn the current clamp zeroing button, the oscilloscope phase is reset, so that the oscilloscope can adapt to what it is doing position).6. Choose the current clamp and oscilloscope to test the sensitivity7. Choose the most suitable method for connecting the current clamp to the oscilloscope.8. The current clamp clamps the current conductor to be measured and starts the measurement..Package List:1 x Clip-On Current Probe1 x ManualNote:1.
