7. Remove all test leads from the test tool to check the zero point.
8. Press
to open the INPUT A MEASUREMENTS menu.
9. Fluke 123/124: press
the select the METER A OPTIONS MENU, and choose:
SMOOTHING: NORMAL | ZERO REF: OFF
10. Fluke 125: press
to switch off ZERO reference.
11. Observe the Input A reading and check to see if it is between 00.00 and 00.10 nF.

3.5.20 Video Trigger Test
This test is based upon use of a TV signal generator. If you have a Fluke 5500A Calibrator
with 600
MHz Oscilloscope Option, there is no need to use a separate TV signal generator.
Fluke 5500A with 600 MHz option can generate video signals. These video signals must be
applied to the test tool via a 50Ω Coax Cable and terminated with a 50Ω feed through
termination. The video signal is simpler than that from a TV signal generator. It consists of
sync pulses and one marker that can be adjusted to appear in the video line the test tool
triggers on.
Only one of the systems NTSC, PAL, or SECAM has to be verified.
Proceed as follows:
1. Connect the test tool to the VIDEO output of the TV Signal Generator as shown in
Figure 3-9.
