Accuracy Performance Tests - Fluke 2680A User Manual

Accuracy Performance Tests

The accuracy performance tests assume you have completed the Performance Test
Setup described earlier in this Chapter. Do not begin the tests until the instrument
has been temperature stabilized for a minimum of one hour.
The tests for the Master Alarm output, Trigger Output, Trigger Input, and DIO
signal lines can either be tested using Fluke DAQ software or using commands
through the RS-232 port. For the RS-232 tests, you will also need to use a program
such as HyperTerminal to perform the test. HyperTerminal is provided as a
standard accessory on Windows systems.

•
