Zero setting (X8/45)
This input signal adjusts the current indication value to zero or to the master
value, respectively. The zero setting is confirmed via the X8/8 output and is
performed as long as the X8/45 input is activated.
The VMF 2000 sets the zero setting value to the combination result.
The VMF 2000 subtracts the zero setting value from the combination result
and adds the master value.
Combination result – Zero setting value + Master value = Indication value
Example:
Before "Zero setting":
82.7 µm - 0.0 µm + (-100 µm) = - 17.3 µm
After "Zero setting":
82.7 µm - 82.7 µm + (-100 µm) = -100 µm
Confirming the zero setting (X8/8)
This input signal confirms the "Zero setting" signal.
*
The function "Zero setting" sets both measuring channels (transducer A + transducer
B) to zero. The individual transducer values can be output via the analogue outputs or
can be inquired via the computer interface with M98/M99.
**
(transducer A - zero setting value A) + (transducer B - zero setting B) + Master value =
indication value
Example:
Before "Zero setting":
(43.7 µm - 0.0 µm) + ((-22.3 µm) - 0.0 µm) + (-100 µm) = -78.6 µm
After "Zero setting":
(43.7 µm - 43.7 µm) + ((-22.3 µm) - (22.3 µm)) + (-100 µm) = -100 µm
