4.1 Real-time OBD-II Pin Voltage การตรวจสอบ
The integrated LCD display shows the real-time Vrms (Root Mean Square voltage) of all 16 OBD-II pins. This allows for quick identification of active signals and power supply status.
- การตรวจจับสัญญาณ: If the device detects a pulse or waveform signal on a pin, the corresponding number background color will flash green.
- Ground (GND) Detection: The display will show "GND" for pins 4 (Chassis Ground) and 5 (Signal Ground) if they are properly connected. If not normal, it will display "OPEN".

4.2 120Ω CAN Termination Switches
The CTB007 PRO includes built-in 120Ω resistor switches for CAN bus lines. These resistors are crucial for compensating for missing termination in single-ECU or small bench networks, which helps improve signal integrity and reduce reflections.
- HS-CAN: Activate the 120Ω resistor for pins 6 and 14 (standard CAN High and CAN Low).
- OEM/MS-CAN: Activate the 120Ω resistor for pins 3 and 11 (vehicle-dependent).
Press the corresponding button (6-14 120R or 3-11 120R) on the device to toggle the 120Ω resistance on or off.

4.3 ECU Testing on Bench
The CTB007 PRO facilitates convenient ECU testing outside of the vehicle. It provides necessary connections for IGN/START activation or external wake-up tools, allowing ECUs to be powered and exercised on a workbench.
- Connect the CTB007 PRO to a 9-32V power supply.
- Use the provided ECU breakout leads to connect the ECU to the CTB007 PRO.
- Connect your scanner or code reader programmer to the CTB007 PRO to communicate with the ECU.

4.4 Battery Replacement Memory Saver
The CTB007 PRO can be used to maintain vehicle power during battery changes, preventing the loss of vehicle settings such as radio presets, clock, and ECU learned values.
- Ensure the car is closed and the ignition key is off.
- Connect the CTB007 PRO to a 12V/24V power supply (either external DC 12V 5.5*2.1mm or a separate 12V/24V battery connected to PIN 5 & PIN 16).
- Connect the CTB007 PRO to the vehicle's OBDII plug. This will power the car's systems, saving ECU data.
- Proceed to safely remove and replace the old battery with a new one.

4.5 ฉบับtage Protection and Alarms
The device provides audible alarms for voltage conditions on PIN 16 (Battery positive +) to alert the user of potential issues:
- ปริมาณต่ำtage Alarm (slow beep):
- 12V systems: < 11.8 V
- 24V systems: < 23.6 V
- ปริมาณสูงtage Alarm (fast beep):
- 12V systems: > 15.5 V
- 24V systems: > 31 V
The CTB007 PRO also features reverse polarity protection to prevent damage from incorrect power connections.
