Taking A Thickness Measurement; Out Of Measurable Range Thicknesses - 493K K-METRON User Instructions

K-METRON Radio User Instructions (Firmware 3.0.4; Doc v4.0)

7 TAKING A THICKNESS MEASUREMENT

When the sensor head is at the desired measuring point pull and hold the orange trigger
and make small figure of eight movements of the Sensor Head to ensure the Transducer
Magnet is centrally located on the Sensor Head. Centring of the calibrated magnet will easily
occur on materials up to 20mm (0.78") thick but will also depend on the surface finish of the
material being measured.
On releasing the trigger, the unit will display and transmit the minimum value measured to
the receiver. The data that are sent to the PC are the Date, Time, Mould Identification
Number, the Mould Position Number and the Thickness Reading.
If the receiver is not connected to the PC or the handheld transmitter is out of radio range
of the receiver then a 'TX Error' will be displayed on pulling the Orange Trigger. The unit is
still operational and can be used to display on-screen readings without the receiver being
connected to the PC, however users should be aware that a 'TX Error' indicates that the
reading is not saved on the PC. If it is not the intention to use the radio link this facility can
be turned off in the Configuration Menu in the "Radio" selection.

7.1 Out of Measurable Range Thicknesses.

During the calibration of a spherical or cube magnet the unit will determine at which
maximum thickness the sensor magnets become out of range and then will display O/R for
'out of range' when appropriate. The O/R limit is reached whenever the effect of the
magnet on the sensor head is too small to provide a useful measurement. It is also seen
when no magnet is present, such as would happen when the magnet becomes de-coupled.
For a limit where the thickness decreases to zero and the measurement is out of range,
"LOW" will be displayed.
