This procedure is divided into subsections (VERTICAL
SYSTEM, TRIGGERING SYSTEM, etc.) and further into
steps (Verify CH 1 and CH 2 50 n Overload Protection,
etc.). This arrangement allows verification of the func-
tionality of the instrument's individual sections, as well as
its conformance to individual specifications, without requir-
ing performance of the entire procedure. Any number of
steps (in any order) can be performed as long as ALL the
parts of a step are performed in sequence and in their
entirety.
Before performing this procedure, ensure that the LINE
VOLTAGE SELECTOR switch is set for the ac power
source being used (see "Preparation for Use" section of
this manual). Connect the instrument to be checked and
the test equipment to an appropriate power source. Turn
the instrument on and ensure that no error message is
displayed on the crt. If an error message is present, have
the instrument repaired by a qualified service technician
before performing this procedure.
Test equipment items 1 through 20 listed in Table 4-1
are required to perform this procedure. The specific pieces
of equipment required to perform the checks within each
subsection are listed at the beginning of that subsection.
The item numbers in parenthesis next to each piece of
equipment refer to the numbered equipment list of Table
4-1. Items 15 and 20 are used only for instrument calibra-
tion (see the Adjustment Procedure-Section 5).
This procedure assumes that the operator is
sufficiently acquainted with this instrument's opera-
tion to obtain the initial and subsequent control set-
tings necessary to perform the procedure. Complete
instructions for setting the controls to obtain the
various operating modes of this instrument are given
in the 2430 Operators Manual.
NOTE
PREPARATION
Within the procedure, steps to verify proper operation
of an instrument control or function that is not specified in
the "Specification" section begin with the word "VERIFY."
These functions ARE NOT specifications and should not
be interpreted as such. Steps to check performance
specifications begin with the word "CHECK."
Removing the instrument cabinet is not necessary to
perform this procedure. All checks are made using the
operator-accessible front- and rear-panel controls and con-
nectors.
This procedure is used to verify proper operation of
instrument controls and to check the instrument's perform-
ance against the requirements listed in the "Specification"
(Section 1). This procedure verifies instrument function and
may be used to determine need for readjustment. These
checks may also be used as an acceptance test and as a
preliminary troubleshooting aid.
