This Focus Meter will measure camera signals from all types of analog cameras and is most useful when
used on the HD type analog cameras like HD-TVI, HD-CVI, and AHD cameras. The BNC type connectors are
used to input the HD and CVBS (base-band composite) video signals. It can also be used to input YPbPr, and
RGB signals by connecting to the "Y" or “G” channel that has the sync signal on it. Only the channel that has
the sync signal on it should to be connected for proper operation. The RGB signal format is measured using one
of the three channels, the Chroma/Sync channel normally the "G" or Green with Sync or any channel can be
measured as long as it has the synchronization signal on it.

DISPLAY FOCUS:
When the unit is in Focus mode the display will react to changes in the camera focus both numerically and
on the bar graph display. The meter is measuring information in the scene and will react to changes in the focus
ring and also changes in the image or content of information in the scene. If you have set the maximum focus on
the camera and you put your hand up in front of the camera you will see the numbers and bar graph go down in
focus. This is caused by the loss of information caused by the change of (in focus) information. When focusing the
camera be sure to stay outside of the image of the camera when setting maximum focus.
CARE AND MAINTENANCE:
No routine maintenance or test procedures are required other than battery replacement. Attempts at field
repair or adjustment will void the warranty.
The HDFM-1 is a precision measuring instrument and should be treated accordingly. While it can withstand
ordinary every day indoor use, it should not be left outside in the rain or otherwise mistreated. It is not waterproof.
The battery should be removed if it is placed into storage to prevent leakage of corrosive fluids from batteries as
they discharge and age.
Replace batteries at least once a year even if ordinary use does not discharge the battery because old
batteries may leak and cause corrosion damage. If the HDFM-1 fails to operate even after battery replacement, or
does not read a known video signal correctly, call the factory for a Return Authorization Number and return it to the
factory for repair.
