6.1 and Selecting the measuring functions
Every push on these keys changes the measuring function ±A ±B
A, -A, 0, A, ... B, -B, 0, B, ...
6.2 and Setting the Offset
The offset can be set for each channel, separately if the measuring function is A or B, or
simultaneously if the measuring function is a combination of A and B. In this case, the off-
set is set equal to both channels A and B.
The offset setting is limited to maxi ±200 µm per channel. This limit guarantees the gauge
heads working range near to their zero position (the most accurate range).
When the maximum value of offset is reached, the red LCD will blink for 2 seconds.
Increment value of displayed function
Quick increment
Decrease value of displayed function
Quick decrease
Zero-set the function (respecting offset tolerance)
Zero-set offset of displayed function,
the symbol
appears below the active channel(s)
A
A B
B
If the measuring function is A±B, the offset of A and B will be set to zero, the symbol
appears below both channels.
Example :
If A represents the measuring function, only
the offset of A will be set to zero, the offset
of B will not be set and vice versa.
