1. AC/DC universal (no overcurrent function available under DC power)
2. Password lock setting function (default 112, after setting the password to fee 112, the parameter range cannot be changed arbitrarily, and subsequent modifications will default to password 112 before parameters can be modified)
3. Manual knife switch function (When the product encounters overvoltage, undervoltage, overcurrent and power failure during use, it will not automatically restore power supply. The power must be manually opened and closed by pressing the power on/off button.)
4. Energy saving electricity consumption (After setting, the brightness of the digital display will decrease, thereby achieving the effect of energy-saving electricity consumption)
5. Quick power failure protection (accidental disconnection, power failure protection will be quickly carried out after disconnection)
6. The frequency usage range is wider, 40/50/60/70Hz
7. The product comes with current, voltage, and frequency correction (professional electricians can manually calibrate it, but it is not recommended for users to use this function)
8. The product’s current accuracy can recognize 0.1A, and the action current can be set in 0.1A steps for adjustable currents above 1A.
9. It is possible to switch between wheel display modes, including voltage (U), current (A), frequency (H), and power (P).
