6.2. Material groups
To change material group proceed as follows:
• Press the F2 key to select the material group.
• Use the navigation keys to choose a material group.
• Confirm selection with the key. If readings were shown on the display, they will now
have been converted using the conversion function for the newly selected material group.
Note: To measure in the native Leeb rebound scale HL, no material group must
be selected, as no conversion is applied. In contrast, hardness scale conver-
sions to other scales are correct only when the appropriate material group is
selected. Free online material databases and the Equotip 3 on-screen help can
be useful to assign your materials to one of the nine material groups. Suitability
of conversions for specific materials should be qualified on calibrated samples
before use. For further advice, please consult Proceq.

Note: For a given hardness scale, the dropdown only lists the material groups
for which conversions are available.
