Instruction Manual

4-11. Performance Tests

The following procedures allow you to compare the performance of your
instrument with the specifications listed in Chapter 1. They are
recommended for incoming inspection, periodic calibration, and to verify
specifications. If the instrument fails any test, calibration adjustment and/or
repair is needed. You do not have to disassemble the instrument to perform
the tests. Throughout these procedures, the 8062A being tested is referred to
as the UUT (Unit Under Test).

4-12. Initial Procedure

For any of these tests, make sure you do the following:
1. Allow the temperature of the UUT to stabilize in a test environment with
an ambient temperature of 23 5 C (73 9 F) and a relative humidity of
less than 80%
2. Check the fuses and battery and replace them, if necessary.
3. Make sure the leads are disconnected from the UUT. Set the power
switch to on and set all other switches to the out (off) positions.

4-13. Microcomputer and Display Test

Use the automatic power-on self-test to test the microcomputer and the LCD
display. Turn the UUT off, then turn it on while observing the display. All of
the LCD segments should turn on. After about one or two seconds, the
display should go blank briefly and then respond to switch selections.
