ETCR9000 series of high and low voltage clamp meters adopt the latest CT technology and mask digital integration technology. The special clamp meter is equipped with high voltage insulating rod. The B type of wireless transmission test data is equipped with wireless receiver, which can receive the measured data within 30 meters in a straight line. If not used with an insulating rod, it can also be used as a high-precision low-voltage clamp meter and leakage current meter to accurately measure 0.1mA of current or leakage current.
The ETCR9000 series high‑low voltage clamp meter is designed for accurate measurement of high‑voltage AC current, low‑voltage AC current and leakage current. It features a CT sensor, digital integration, peak‑hold, data‑hold, data‑storage and, for the B‑type, wireless data transmission up to about 30 m.
The manual provides safety warnings, a description of the instrument’s structure and LCD display, step‑by‑step operating procedures for both the detector and the optional wireless receiver, battery replacement instructions, and a packing list. Technical specifications such as measurement range, resolution, sampling rate and environmental limits are also listed. This manual is written in Chinese.

The instrument can store up to 99 groups of data.
The B‑type wireless transmission works up to about 30 meters in a straight line.
When the measured line voltage exceeds 600 V, an insulated rod must be connected to the instrument.
Open the battery cover, replace the four AAA alkaline batteries with correct polarity, close the cover tightly and verify operation.
