Performance Tests

Introduction

This section provides the test procedures used to verify that the 4349B's speci cations listed
in Chapter 8, General Information, of this manual are met. All tests can be performed without
access to the interior of the instrument. The performance tests can also be used to perform
incoming inspection, and to verify that the 4349B meets its performance speci cations after
troubleshooting or adjustment. If the performance tests indicate that the 4349B is NOT
operating within the speci ed limits, check your test setup, then proceed with troubleshooting
if necessary.
Note
Allow the 4349B to warm up for at least 30 minutes before you execute any of
the performance tests.
Perform all performance tests in ambient conditions of 23  C
Note
RH.

Test Equipment

Table 9-1 lists the test equipment required to perform the tests described in this section. Use
only calibrated test instruments when performance testing the 4349B. Equipment which equals
or surpasses the key required speci cations of the recommended equipment may be used as a
substitute.

Calculation Sheet

The calculation sheet is used as an aid for recording raw measurement data, and for calculating
the performance test results.
The performance test procedure gives the test sequence for performing a test, the complete set
of measurement data are recorded on the calculation sheet, the results are calculated using the
equations given on the calculation sheet, and the results are transcribed to the performance
test record.
The procedure for using the calculation sheet is:
1. Photo copy the calculation sheet.
2. Follow the performance test procedure and record the measurement value(s), the 4349B's
reading, etc., into the speci ed column on the calculation sheet.
3. Calculate the test result using the appropriate equation given on the calculation sheet, and
record the test result into the Test Result column of the performance test record.

Performance Test Record

Record the performance test results in the test record at the end of this chapter (Photocopy the
test record and use the photocopy). The test record lists all test speci cations, their acceptable
limits, and measurement uncertainties for the recommended test equipment. Test results
recorded during incoming inspection can be used for comparison purposes during periodic
maintenance, troubleshooting, and after repair or adjustment.

Calibration Cycle

The 4349B requires periodic performance tests. The frequency of performance testing depends
on the operating and environmental conditions under which the 4349B is used. Verify the
4349B's performance at least once a year, using the performance tests described in this section.
