Proceq Equotip 3 Operating Instructions Manual page 23

7.1.4. Measuring reference samples
• Sample surfaces must be prepared very carefully. If possible, samples shall be of a size
which makes coupling to a support base unnecessary.
• The functioning of the Equotip 3 shall be verified against the Leeb test block prior to each
measurement series.
• The functioning of the static hardness testing machine (HV, HB, HRC etc.) shall be verified
against respective test blocks of the corresponding measuring scale and range.
• To obtain a pair of comparative values, the mean values from at least 10 to 15 HL
measurement values and from 3 values from the static test shall be calculated. These
values shall be obtained from proximate positions in a small measuring area.
