I couldn't find an EEVblog-thread for this scope-based current clamp or any feedback, even though it's an older fellow, and curious if anybody had first-hand knowledge with this current clamp for relatively low amps (Max60A) or perhaps tried to optimize it, as it looks to be a very noisy fellow. Specs: ETCR 007AD AC/DC Clamp Leakage Current transducer * Function Measurement of AC/DC current, leakage current *Power Supply Zn-Mn dry battery, 6RL61, 9V. Continually using for 100 hours, connecting external power supply is also available for long time using. *Test Mode Clip-on CT, non-contact measurement *Clamp Size Φ7mm *Input Range 0mA-60.0A AC/DC *Output Voltage 10mV/A;100mV/A(corresponding) *Output Range 1V peak max *Resolution 1mA AC/DC *Accuracy ±3%FS(23℃±5℃, below 5%rh) *Phase Error ≤3°(AC 50Hz/60Hz; 23℃±2℃) *Calibration Adjust ZERO to calibrate, eliminate external electric field interference *Output Wire Core wire: signal positive output; shielding wire: signal ground *Lead length 2m *Dimension LWH: 168mm×65mm×34mm *Frequency AC: 45Hz-400Hz DC: DC-100kHz *Test Position Tested wire in the jaw center *Line Voltage AC600V *Weight 170g (Including the battery) *Working Current 5mA *Working Temperature and Humidity -10℃-50℃,below 80%rh *Limit Temperature Error -10℃-0℃ and 40℃-50℃, within 2%rdg *Storage Temperature and Humidity -10℃-60℃,below 70%rh *Insulating Strength AC3700V/rms (between the alloy of the clamp and the housing) *Applicable safety rules IEC1010-1, IEC1010-2-032, Pollution level 2, CAT Ⅲ(600V) *Accessories Sensor: 1piece; Battery(6F22,9V): 1piece; User Manual/Warranty card/ Certification.

They were around 50US back in 2019/2020, so a tad more expensive than other budget-orientated AC&DC BNC-based current clamps for scopes, like fx Hantek CC-65 (DC 20KHz). Here in 2023 - it looks like US sources like Newegg & Amazon are selling them for 3x to 3.5x their inner-price a few years back. https://www.newegg.com/p/2S7-07JP-2BCA2?item=9SIB33YJF64204 & https://www.amazon.com/ETCR-007AD-Leakage-Current-transducer/dp/B017YGOWQK Manual [pdf] http://file.yizimg.com/492225/2016112-16458399.pdf [007AD Page+4] Vendor https://www.etcrmeter.com/etcr007ad-ac-dc-clamp-current-sensor-50a_p160.html // https://www.etcr-instruments.com/index.php/qxjzldlhgqjddzcsyjydzcsyzldzcsyqxdlbgdyqxdlbgyydqd/1982.html |
