Scale
HB
- Brinell hardness
HRB
- Scale B Rockwell
HRC
- Scale C Rockwell
HV
- Hardness according to Vickers
MPa
- tensile strength
no conversion
Comments:
❶
Because different hardness scales can have different ranges, it is sometimes not
possible to make a conversion. If this is the case, the symbol "---" is displayed.
❷
The set material group must be reset if the tensile strength (MPa) is selected.
❸
As is generally known, the conversion is for reference purposes only. Comparative
tests are required to ensure an accurate conversion.
Limit values
The max. limit value and the min. tolerance value are
adjustable. If the measured hardness values are
outside the range, the display immediately triggers a
sound alarm.
The minimum and maximum limit values can be set
using a digital keypad (Fig. 3-6).
To select a different position or digit, press
the or
key.
Statistics
The device is equipped with an automatic statistics
function. It allows you to set statistical parameters to
determine the average ( ) and range value (S).
Important:
❶
The value range for statistical parameters is 1 ~
99, whereby with the setting "1" no statistical
processes are carried out by the system.
❷
If some items (material group etc.) are reset, the
count starts from "0".
