X-MET 3000 TX XRF Analyzer 5.0 PRE-INSPECTION START UP AND CALIBRATION

5.1 The X-MET 3000 TX XRF analyzer will be turned on and logged in (password entered). It will then be allowed 10 minutes time stabilize before Proceeding.

5.2 After the program is started, the program will prompt to make an

energy calibration measurement. This is done by measuring the DUPLEX 2205 sample supplied with the instrument.
