FM Systems Camera Master CM-1V. This item is used but in new condition. Guaranteed not to be DOA. Below is some information from Camera Master website. Thanks.
Industry: TV/Radio Broadcast, CATV Cable Industry
The Camera Master is a digital, hand-held, battery operated meter that measures five different characteristics of the video signal from a CCTV camera or other video sources, such as:
SYNC (.28 VOLTS) Enables the camera to be set to the correct video output level.
WHITE (.71 VOLTS) Enables the camera Iris to be accurately adjusted to the correct brightness setting.
COMPOSITE (1 VOLT) Measures overall level of the video signal. One Volt Peak to Peak.
COLOR BURST (.28 VOLTS) Measures color burst amplitude on the Back Porch of video. Used to adjust cable equalizers to offset cable slope loss.
FOCUS Used to adjust camera for best focus on scene. Maximum meter reading occurs at sharpest focus. No need for a TV monitor at the camera location.
The Sync, White, and Composite amplitude measures the sync-to-white ratio and the overall video waveform amplitude on any part of an NTSC or PAL video system, including camera origination, video levels in Distribution Amplifiers, TV Switchers, Studios, Microwave and Satellite transmission systems.
The small size of the Camera Master enables it to be taken directly to the camera location, thus saving time and in many cases, reducing test and installation manpower.
