How do I identify my DIT-MCO analyzer model and serial number?

Locate the gray DIT-MCO identification tag on the analyzer back panel. It may list the analyzer model, system number, serial number, assembly information, input voltage, and switching configuration. On Model 2635 systems, the label is on the outside of the Pelican case. Model 2115 uses Series 17 switching; Models 2635 and 2650 use Series 10.
