Page 6: Introduction
I. Introduction 1. Principle of the meter HT2672 Digit Megohmmeter consists of medium and large scale integrated circuit with high output power and high short-circuit current value features. The output voltage is up to four grades. The built-in battery served as power supply become high DC voltage by DC/DC transformation, which goes from E pole to L pole via the object being tested. -

transformers, motors, cables and electrical equipment. II. Function and Features The meter has the following features: 1. High output power, strong load ability, and strong anti-interference ability. The shell body is made of aldural/high-strength aluminum alloy, equipped with potential protection ring and fourth-order active low pass filter, it can play an effective role in shielding external power frequency and strong electromagnetic field. -

2. Output voltage grades, measuring range, resolution, error Output voltage grades: 500V，1000V，2500V，5000V Measuring range: 0~19990MΩ Resolution: 0.01MΩ，0.1MΩ，1.0MΩ，10.0MΩ Relative error: 0~2000MΩ≤±5%±2d, 2000MΩ~19990MΩ≤10%±2d 3. Load ability of maximum output voltage and short-circuit current Voltage/Load: 5000V/40MΩ Voltage drop: Approximately 10% Short-circuit current: >1.6mA 4. - Page 9 500V. Select the required voltage grade and the indicator light will show the selected voltage grade. Press the high voltage “start/stop” button and the indicator light for high voltage will glow. The stable value displaying on the LCD multiplied by 10 is the measured insulation resistance value.
