10.4 Troubleshooting Using Test Function Values
The Model 300M provides the capability to display, on operator demand, the values of Test Functions which allow the observation of key analyzer operating parameters. These Test Functions can be accessed by depressing the TEST Button on the instrument's front panel causing the next test function to be displayed. By comparing the values of Test Functions to acceptable operating limits, it is possible to quickly isolate and correct most problems.
