The TESTFOX CC–1 has an automatic switch-over of measurement range.
Previous setting is therefore not required.

7.2 AC voltage range
The input resistance is 9 MΩ parallel 100 pF. The measurement reading is
obtained by rectification of the average reading and displayed as the actual
value. Its calibration is adapted for a sinusoidal curve form. With deviations from
this form, the display value becomes less accurate. The additional error for the
following crest factors is as follows:
crest factor of 1.4 to 2.0: additional error ± 1.0%
crest factor of 2.0 to 2.5: additional error ± 2.5%
crest factor of 2.5 to 3.0: additional error ± 4.0%
