4 Measurement and Calibration
4.1 Performing a measurement
4.1.1 Turning the power on and off
Start up the RQ8000 with a short press of the power button marked with
.
All LEDs are lit for a short period and the device should be ready for measurement with the power LED
turned green.
You may choose to read a barcode from a roll (as instructed in section 3.2), create a new roll tag from
scratch with barcode/new roll button (3.3) or proceed to the actual measurement (section 3.4.)
4.1.2 Using the barcode reader to read a new roll tag
The barcode button activates the camera which is used to acquire barcode information from a roll label.
The barcode distance should optimally be some 10-20 centimeters away from the front end of the
RQ8000and the green line projected to the surface should be visible and uniform. The barcode does
not need to be in line with the guided line nor does the RQP need to be turned to a similar angle, the
camera is able to read barcodes from any direction. To ensure fast recognition of the barcode the RQP
device should be directed towards the barcode while starting the reading.
The Barcode LED
should flash a green light when a barcode is successfully recognized. If the LED
blinks red the device was not able to recognize the barcode before timeout.
You may retry by pushing the same button
.
4.1.3 Using the barcode button to create a new roll tag from scratch
If the measured rolls do not have barcode IDs but you wish to create a marker to separate your
measurements from each other (for different rolls for example) you can press the barcode reader button
to mark them. This will create a separate directory for a measurement or a group of measurements
each time the button is pressed.
4.1.4 Measurement
Place the RQ8000on the surface or roll you wish to measure and move the measurement head forward
with firmly holding it against the surface. The hammer will hit rapidly while the distance wheel is turning
and the required force against the wheel is detected.
Keep the movement steady and make sure that you have a firm grab of the measurement head when
moving it over the edge of a roll.
If the measured surface or the length of the measurement is extremely short then the preferred method
of ending a measurement of a profile is to stop moving the head forward and to lift the measurement
head away from the surface.
The measured profile is now saved to the SD disk.
4.2 Measurement Speed
RQ8000 measurements are considerably faster than other methods of roll profile measurement. For
optimal results the measurement has to be steady and controlled and if the analysis requires more data
this can easily be achieved by slowing down the measurement speed. For normal measurements the
speed may be something from 5cm per second and for very precise measurements the speed can be
as low as 1cm per second. This will result to more measurement points and larger data to be analysed.
