Avoid application crash with catchError

I know that if I use the catchError pipe operator in my application I can avoid the 'break' of the application so when it comes back the service keeps on rooting

.pipe(
     catchError( error => from([]) )
  );

How do I use this operator when calling the service to avoid crashing

I tried this way:

this.meuService.getValues('63').pipe(
      catchError(error => from([]))
    ).subscribe( (medidor) => {
      this.setarValores(medidor);
    });

The goal is for your to stop my service node, the application keep trying to read the data
