Performance Verification Procedures
This chapter contains procedures for functional verification, certification, and
performance verification procedures for the TLA715 Portable Mainframe.
Generally, you should perform these procedures once per year or following
repairs that affect certification.
Summary Verification
Functional verification procedures verify the basic functionality of the instru-
ment inputs, outputs, and basic instrument actions. These procedures include
power-on diagnostics, extended diagnostics, and manual check procedures.
These procedures can be used for incoming inspection purposes.
Certification procedures certify the accuracy of an instrument and provide a
traceability path to national standards. Certification data is recorded on calibra-
tion data reports provided with this manual. The calibration data reports are
intended to be copied and used for calibration/certification procedures.
After completing the performance verification procedures or the certification
procedures, you can fill out a calibration data report to keep on file with your
instrument.
Performance verification procedures confirm that a product meets or exceeds the
performance requirements for the published specifications documented in the
Specifications chapter of this manual. Refer to Figure 4--1 on page 4--2 for a
graphic overview of the procedures.
Test Equipment
These procedures use external, traceable signal sources to directly test character-
istics that are designated as checked (
n
) in the Specifications chapter of this
manual. Table 4--1 on page 4--3 shows the required equipment list. Always
warm up the equipment for 30 minutes before beginning the procedures.
