KYORITSU KEW-2040 / KEW-2055 Clamp Meter User Manual
The manual begins with safety and warning information, describing the IEC‑61010 compliance, protection class, and proper handling to avoid electric shock or equipment damage. It also lists the physical design features such as double‑layer housing, backlight (KEW‑2055 only), and battery‑saving auto‑off.
Subsequent sections detail measurement functions—including AC/DC current, voltage, resistance, continuity, diode test, frequency/DUTY, and NCV—along with range selection, zeroing, MIN/MAX, HOLD, and backlight operation. Technical specifications, battery replacement, and maintenance procedures are also covered. This manual is written in Chinese.
