Product Introduction
The UHV-2671A Digital Megohmmeter, manufactured by Wuhan UHV, is designed using medium- and large-scale integrated circuits. This meter features high output power, a high short-circuit current value, and multiple output voltage levels.
The operating principle is as follows: the DC high voltage generated by DC/DC conversion from the internal battery serves as the power source. This voltage is applied from the E terminal to the L terminal through the device under test, generating a current flow from E to L. After I/V conversion and division, the measured insulation resistance value is directly displayed on the LCD screen.
Product Characteristics
1. Auto Discharge Function: Ensures safer operation by automatically discharging residual voltage.
2. LCD Backlight: Provides clear visibility in low-light conditions.
3. Live Wire Warning: Features audible indication to alert users when a live wire is detected.
4. Auto Power-Off: Automatically powers off after 10 minutes of inactivity to conserve battery life.
5. Low Battery Indication: Alerts the user when the battery level is low, ensuring timely replacement or recharging.
