I . Introduction of Product Functions
Welcome to use our company's Draw Monitor product. This product is designed for
use in monitoring car battery voltage, leakage current, and serving as a backup power
supply when replacing the battery. The product is connected to the car's OBDII interface
via an OBDII connection cable to supply 12V power to the car and monitor the car
system's leakage current for diagnosing various faults. It can also serve as a backup
power supply for the car during battery replacement, preventing the car's mainboard
from losing power and data. Draw Monitor can also monitor battery voltage through the
OBDII port. Please read this manual carefully before using the product.

When the device is powered off, long press the power button to turn it on, and long
press the power button to turn it off when it is powered on.
2. Smart Output
The smart output function generates a 12V voltage. If this voltage is higher than the car
battery voltage, it will output power through OBDII; otherwise, the output will be cut off
to monitor the battery voltage. By default, smart output is turned off after booting up.
Press the smart output button to activate it, and press the smart output button again to
turn it off.
3. Graphic Mode
The graphic mode is different from the normal display mode. This mode displays the
voltage and current values from the last 20 seconds as a waveform on the LCD screen.
The default mode after power on is the normal display mode. Press the Graph button to
switch to graphic display mode, and press the button again to return to normal mode.
