This document introduces the panel description and technical specifications of the automotive digital clamp meter ADD9702 produced by Beijing Aideshengye Technology Co., Ltd. The clamp meter has multiple functions such as testing DC/AC current, DC/AC voltage, frequency, duty cycle, resistance, diode, capacitance, and short circuit buzzer test. It features a large LCD display, automatic power off, and data hold.
This manual describes the ADD9702 digital clamp meter used for automotive diagnostics. It details the panel layout, key functions such as DC/AC current, voltage, frequency, resistance, diode, capacitance and short‑circuit buzzer tests, and explains how to select and operate each measurement mode.
Safety warnings, battery‑low indicators, zeroing functions, data‑hold, and step‑by‑step maintenance procedures—including battery replacement and probe handling—are covered. The document also includes application notes for measuring vehicle electrical systems such as alternator leakage, starter current, and motor diagnostics. This manual is written in Chinese.
