Adjust LCD brightness: Use keys number 7 (BR+) and 9
B. Measure signal strength (Vpp) and attenuation:
Video signal strength (attenuation): With the tester displaying the video signal (see A), press the “1” (IRE) key. The following is displayed:
MAX Vpp: The
AVERAGE Vpp: The average
SYNC SIGNAL: A camera’s sync pulses synchronize the camera with the monitor.
NO VIDEO: No signal, “No Video” will be displayed.
Example of attenuation: If the Vpp at the camera is 1.25 Vpp, and the Vpp at the end of the cable is 1.15 V, the attenuation is 8%.
C. Testing and controlling the camera motion (PTZ):
Connection. Connect the camera to the tester as shown in Figure
ADDRESS:001 | > Enter the PTZ camera’s ID |
