Incoming Inspection
Incoming Inspection
This section contains functional/operational checks appropriate to an incoming
inspection.
The waveform monitor must have been operating for a warm-up period of at least
20 minutes, and must be operating at an ambient temperature. (See Table 44
on page 35.)
Use the following procedures to check the basic functionality of WFM6120,
WFM7020, a
nd WFM7120 Waveform Monitors. The checks are arranged by
model and option so that you can choose the sections that are appropriate for your
instrument. The last two sections are for less critical waveform monitor features:
the ground closure and Ethernet ports. You need only test these if you intend to
use them. In general, you should test in the order presented, since later tests might
depend on items checked in the earlier tests.
