Function key “Infinite”.
Now the message should
disappear and the gauge is ready
for measurement.
Attention:
Make sure not to press the
Infinite function key unless you
have removed the error sources
(target ball, magnetic field or
metallic parts).
“Refresh infinite value !!!”
(The infinite value should be
actualized)
To ensure the guaranteed
measuring accuracy, the infinite
value must be refreshed.
See also section 6.1
Remove target ball from sensor.
If the message persists, please
press Refresh function key.
During a measurement you can
press ESC in order to cancel the
Refresh procedure.
“Sensor type not compatible with
batch ! “
“Service failure”
(MiniTest 7400 FH only)
Another sensor has been
specified for the active batch.
Select or create another batch.
“Batch readings do not match
connected sensor !”
“Delete readings?”
Another sensor has been
specified for the active batch.
Select or create another batch or
add sensor data of the sensor
currently being used.
“Please check for correct target
ball size!”
You have probably selected a
wrong target ball.
Make sure the adjusted target
ball size matches the target ball
used for measurement.
“Please check sensor and target
ball position!”
Make sure there is not target ball
positioned laterally to the sensor
tip. Make sure to keep the sensor
out off the influence of ferrite
objects or magnetic fields.
Remove target ball from sensor.
Keep away from ferrite objects or
magnetic fields.
“Carry out Zero measurement
and the gauge will be ready for
measurement again.
The magnetic field of the sensor
has been influenced e.g. by a
target ball laterally to the sensor
tip or by any magnetic field.
Place target ball matching to the
adjusted target ball size on the
sensor tip. This step is required to
make the gauge ready for
