1710J-Series Waveform Monitors
1. Display any standard television waveform. Do not enable the rear–panel
REMOTE connector RGB enable.
2. Use the 1710J–Series Waveform Monitor HORIZONTAL position control to
align the display with the graticule.
3. Ground the REMOTE connector RGB Enable (pin 2) and apply the camera
staircase output to the RGB Staircase input (pin 1).
4. Apply the camera video output to the 1710J–Series Waveform Monitor
INPUT (CH A or CH B) and select that input with the front–panel INPUT
switch.
5. Adjust R856 (see Figure 8–1 for location) to center the RGB signal on the
graticule.

Preventive Maintenance
Preventive maintenance consists of cleaning, visual inspection, performance
checking, and, if needed, readjustment. The preventive maintenance schedule
established for the instrument should be based on the environment in which it is
operated and the amount of use. Under average conditions, scheduled preventive
maintenance should be performed every 2000 hours of operation.
Cleaning and Inspection
Preventive maintenance consists of cleaning and visual inspection. The schedule
depends on the severity of the operating environment. Under average conditions,
perform preventive maintenance after 2000 hours of operation.
Clean the entire instrument often enough to prevent dust and dirt from accumu-
lating. Dirt can act as a thermal insulating blanket that prevents effective heat
dissipation. In addition, dust buildup can provide high–resistance electrical
leakage paths between conductors or components in a humid environment.
Exterior. Cleaning the exterior consists of an occasional wiping of the outside
surfaces with a damp soft cloth. Do not use commercial cleaners because they
could discolor or damage the finish.
Check all air vents on a regular schedule to ensure that there is not a dust buildup
that could impede the flow of cooling air.
