The three levels of test procedures described in this chapter are used
to verify that the HP E1411 multimeter:
is functional (Functional Verification)
meets selected testable specifications (Operation Verification)
meets all testable specifications (Performance Verification)
Do not perform any of the following verification tests unless
you are a qualified, service-trained person and have read the
WARNINGS and CAUTIONS in Chapter 1 - General Information .
For valid tests, all test equipment and the multimeter must have a one hour
warmup, the line voltage must be 115/230 Vac 10%, and multimeter Auto
Zero must be set to ON. See Table 1-1, Recommended Test Equipment, for
test equipment requirements.
For best test accuracy, the ambient temperature of the test area should be
o
o
between 18
C and 28
C and stable to within 1
Performance Verification tests at least once a year. For heavy use or severe
operating environments, perform the tests more often.
The verification tests assume the person performing the tests understands
how to operate the mainframe, multimeter and specified test equipment. The
test procedures do not specify equipment settings for test equipment, except
in general terms. It is assumed a qualified, service-trained person will select
and connect the cables, adapters, and probes required for the test.
Table 4-1, Performance Test Record for the HP E1411 Multimeter, at the
end of this chapter, provides space to enter the results of each Performance
Verification test and to compare the results with the
upper and lower limits for the test. You can make a copy of this form,
