User manual for the K1 and K2 current probes, covering safety, operation, specifications, maintenance and warranty.
This manual provides instructions for safely using the K1 and K2 current probes, which measure low DC or AC currents without breaking the circuit. It includes safety precautions, operating steps, zero‑adjustment, measurement procedures and overload indication.
The document also details technical specifications, mechanical dimensions, environmental limits, battery replacement, cleaning, calibration and warranty information for the probes and their portable case. This manual is written in Chinese.

Do not use the K1 or K2 current probe on conductors or cables exceeding 300 V.
Close the probe jaws, connect the adapter box to the instrument, press the zero‑wheel switch and adjust until the display reads zero.
The K1 probe measures DC currents from 1 mA to 4.5 A and AC sinusoidal currents from 1 mA to 3 A (45‑65 Hz).
