2GENERAL OPERATION

2.1 Turning the unit ON & OFF.

To turn the unit ON momentarily press the ON/OFF switch on the face of the K-METRON

until the Display illuminates. Battery level will be checked each time the unit is turned on,

and if a low battery voltage is detected then a warning will be displayed on start up.

To turn the unit OFF, momentarily press the ON/OFF switch on the face of the K-METRON

until Display goes off.

The unit will auto power off after 3 minutes of inactivity. A warning “PWR OFF” is displayed

after 1 minute of inactivity. The unit can be interrupted from auto power off by pressing

either the orange trigger or the X (or “Delete”) button; pressing either will only interrupt the

auto power off and will neither ‘transmit’ nor ‘delete’ any data.

2.2 Entering the Configuration Menu.

To enter the configuration menu, where Magnet Type, Calibrate, Units, and Radio Menus

are stored, use the following button presses starting from when the K-METRON is in the OFF

state:

1. Hold down the X button (or “Delete” button in older models) and switch the unit on

by pressing the On/Off button.

2. Continue to hold down the X (or “Delete”) button, the display will read “Wait …

Setup mode”.

3. Continue holding down until the display reads “MAG TYPE”then release the X (or

“Delete”) button. (Ensure that the orange trigger is not being mistakenly held down).

4. Once the display reads “MAG TYPE”, the unit is now in the Configuration Menu.

The Configuration Menu is navigated using the following buttons:

To SCROLL through the Menus, press X (or “Delete”).

To SELECT a Menu item, press the ORANGE TRIGGER.

2.3 The Measurement End of the Sensor Head

The measurement end of the sensor will attract the magnet. Ensure this end of the sensor is

in contact with the surface of the part to be measured.

2.4 Coupling the Sensor Head with the Calibrated Magnet.

Place the Sensor Head on one face of the product that is to be measured. Hold or place the

magnet on the opposite side of the product wall until it couples to the sensor head.

Hollow objects can be measured by inserting the calibrated magnet through a small opening

in the product. The magnet should immediately be coupled with the sensor head positioned

on the outside of the product and adjacent to the aperture. The sensor head can then be

slid over the surface of the product to the desired place of measurement. Movement should

be slow and steady. Care should be taken when moving the sensor head to avoid de-

coupling.

2.5 Loss of Magnetic Coupling.

When magnetic couple of the cube magnet is lost it can be retrieved by retaining the end of

the attached cord and fishing the magnet out of the opening. If the spherical magnet loses

coupling, then it must be retrieved by turning the moulding upside down and allowing the

magnet to fall out or by using a telescopic metal pointer to grab it.

2.6 Tracking the Sensor Head to the Point of Measurement.

The calibrated magnet will automatically couple, orientate and centre itself over the Sensor

Head. Once coupled track the Sensor Head to the point on the part which you wish to

measure, taking care not to remove the sensor head from the face of the work piece. This

may result in the loss of the magnetic coupling. The calibrated magnet will follow the Sensor

Head to the desired point of measurement.

2.7 Inserting the Sensor Head in the Dock.

If the sensor head is difficult to engage in the Sensor Head Dock, then a thin film of grease

should be applied to the O-ring found within the Sensor Head Dock.

3MEASURING DIFFERENT MATERIALS

The unit does not require re-calibration for use with different materials. This equipment will

measure materials of a thickness between 2mm to 20mm where access can be achieved to

both sides of the product being measured.

3.1 Materials that can be measured.

Non-ferrous materials of any density will return an accurate reading within the limits of the

device. Materials that can be measured include all non-ferrous materials such as:

•Plastics of any density or composition

•Foamed materials

•Laminates

•Fibreglass

•Carbon Composites

•Glass

•Aluminium

•Brass and copper

The K-METRON allows the roto moulder to measure the full thickness of MULTI-LAYER

mouldings.

3.2 Materials that Cannot be Measured.

The unit cannot be used to measure any kind of ferrous materials, e.g. steels & irons. The

magnetic attraction found in these materials will affect the accuracy of the reading.

3.3 Measuring Non-ferrous Metal Parts.

When measuring the thickness of non-ferrous metal parts (e.g. aluminium or copper) ensure

that there is no movement of the magnet during the measurement. The figure of 8

movement for these materials should be made to centre the magnet to the sensor head

but should be stopped once centred and before the measurement is taken.

4CALIBRATING THE K-METRON

The unit may come with calibrated data already recorded for each of the magnets held in

the unit’s memory; this will be confirmed if a Calibration Certificate has been sent with the

unit. The calibrated data associated with each type of magnet will be automatically called on

selection of the magnet from within the configuration menu. After the K-METRON is

calibrated with each type of magnet the values are stored within the K-METRON memory.

Therefore, re-calibration is not necessary when switching between magnets; instead, the

desired magnet is chosen in the configuration menu under the MAG TYPE section.

The K-METRON’s accuracy improves with careful magnetic coupling between the sensor

head and the part face. Measurement accuracy ranges from +/- 0.2mm at the lower end of

the readings and +/- 1mm at the upper end of measurement. This will depend on whether

the spherical magnet or the cube is used.

Although the units are calibrated before leaving 493K re-calibration may be necessary

within your plant. This can be determined by selecting the appropriate magnet and

validating the data as described below in section 4.3 Validating Calibration.

Select a location that is at least 1 metre away from any steel or ironwork which will affect

accuracy of calibration.

Re-calibration is not required for use with differing materials.

4.1 Entering the Calibration Menu.

The Calibrate Menu is found within the configuration menu. Use the following button

presses, starting from when the K-METRON is in the OFF state, to enter the Configuration

menu:

1. Hold down the X button (or “Delete” button in older models) and switch the unit on

by pressing the On/Off button.

2. Continue to hold down the X (or “Delete”) button, the display will read “Wait …

Setup mode”.

3. Continue holding down until the display reads “MAG TYPE” then release the X (or

“Delete”) button. (Ensure that the orange trigger is not being mistakenly held down).

4. Once the display reads “MAG TYPE”, the unit is now in the Configuration Menu.

The Configuration Menu is navigated using the following buttons:

To SCROLL through the Menus press X (or “Delete”).

To SELECT a Menu item, press the ORANGE TRIGGER.

Scroll through the menu using the X (or “Delete”) button and select “Calibrate” by pulling

the orange trigger. The unit will prompt for re-confirmation, and this is acknowledged again

by pulling the orange trigger.

4.2 Calibrating the K-METRON.

Once in the Calibrate Menu the display should now read NM –no magnet. With no magnet

near the sensor head, the trigger should be depressed and released.

After successfully acknowledging ‘NM – no magnet’ the unit will then request the 20mm

position (+10mm disk for 10-30mm magnet). The magnet should be placed on the

20mm(+10mm disk for 10-30mm magnet) step and the trigger pulled. Confirmation of step

calibration will be provided and then the next step thickness requested, i.e. 19mm. Slide the

magnet onto the next step ensuring that it does not snap onto the next step to avoid

damaging both the magnet and calibration step tool. The next position will be requested,

i.e.18mm, and so on.

The magnet should be placed on each step so that it is in the centre of the step and is not

interfering with the step edge. The sensor head should be centred on the magnet. Ensure

that the magnet is not moving when calibrating as this will affect the calibration values.

The more accurately you can teach the K-METRON the thickness that it is measuring during

calibration, the greater the accuracy of the part thickness measurement in the field.

Continue this step-by-step calibration down to the ‘Zero’ thickness with the magnet directly

on the sensor surface.

If you make a mistake during the calibration sequence, press the X (or “Delete”) button to

go back to the previous position.

For use of 19mm Spherical Magnet to use for the 10mm-30mm measurement range:

Please note that a 10mm aluminium Disk is provided.

The disk features a groove for the sensor head to easily slide into, allowing the operator to

calibrate +10mm in conjunction with the provided calibration step profile.

THE CUBE AND SPHERICAL MAGNETS ARE NOT INTERCHANGEABLE AND DOING SO WILL

RESULT IN INACCURATE READINGS. THE MAGNET TYPE MUST BE SET IN THE

CONFIGURATION MENU BEFORE USING THE K-METRON. IT IS ADVISABLE TO STORE ANY

UNUSED MAGNETS IN THE K-METRON CASE TO AVOID MISTAKENLY LOSING OR USING THE

WRONG MAGNET.
