What are the DIP switch positions to allow auto ranging?
All APMs are shipped from the factory in auto-ranging mode.
If you have changed the configuration and want to return back to auto-ranging:
- Make sure that all the DIP switches on the rear of the unit are pointing to the left (away from the screw terminals) as shown below.
- Run the APM configuration software and select ‘Auto Ranging’ before writing the configuration to the APM.
