Functions & Configuration

Key Features:
●Measuring range: 300mA～300,000A
●Typical bandwidth: 1Hz～13MHz
●Slim, flexible high-performance sensing loop
●Near-zero interference: during measurement, the actual load current is only a few picohenries
●Easily connects to the actual measurement object
●The sensing loop's peak voltage insulation capability can reach 10KV
●The sensing loop circumference ranges from 300mm～1000mm; beyond this range, it can be customized according to the customer's actual needs
●The instantaneous voltage output is ±6V peak-to-peak, which can be directly connected to oscilloscopes, data acquisition devices, digital voltmeters, and power recording devices, and can also be used as a trigger output
●Accuracy up to 1%

●Newly improved build quality – new "clip in" sensing loop feature
New power supply - allows the use of 4 standard 15VAA alkaline batteries, can operate continuously for 70 hours, with an additional 12—24V DC socket
New high sensitivity and high measurement range – can measure 30A, 60A, and 150A peak currents
New automatic DC offset elimination

*1 Maximum noise (mVpk-pk) Distributed around the low-frequency bandwidth (-3dB)
*2 High-frequency bandwidth (Hz) High-frequency bandwidth depends on the length of the loop section; maintain the FH values of other PEM contact loops
