SPRING LOADED ROLLER FOR DUST TEST TAPE
SP3600
1SAFETY PRECAUTIONS
•Always keep the instrument in its case when not in use.
•Though robust in design, this instrument is precision-machined. Never drop it
or knock it over
•Clean the instrument with a damp soft cloth. Never use abrasives or solvents.
2PRODUCT DESCRIPTION
The Spring Loaded Roller is used to perform objective dust tape tests, as mentioned in ISO 8502-3, and
eliminates the human factor. The Spring loaded roller is so designed that it is capable of applying a load of 44,13
N. Iso 8502-3 quantifies the quantity and size of dust particles on surfaces prepared for painting. This test has to
be performed just before the paint is applied. The test itself is not included in the delivery

5PERFORM A MEASUREMENT
•Cut a piece of 20 cm from the special specified dust tape(SP3209) supplied with the Dust Test Kit SP3200 or
the PreTreatment Kit SP7315/7316.
•Apply the tape at an appropriate location and rub 3 times by thumb with a hand force of approx. 4-5 kg.
•Take the Spring Loaded Roller and place it axial over the applied tape before.
•Press and hold down the roller till all wheels are in contact with the surface to assure the specified force of
44,13 N is applied.
•Move the spring roller, while holding it down, 3 times for and backwards over the tape.
•Peel the tape off by taking it on one of the corners and apply it on a Sample Transfer Sheet (SP3221) to

5PERFORM A MEASUREMENT
5.1 Measuring Roughness
1. Press the On/Off button to switch the gauge on.
2. Check if the right tip is chosen. (the sharp needle tip is suitable for measuring roughness)
3. Choose parameter by pressing the IN/MM button.
4. Place the needle of the gauge on the flat glass specimen (zero plate) and press the gauge with the
holder down until the base of the holder stands firmly on the zero plate.
5. Press the ZERO button to make the instrument read zero.

|
6. Place the needle gentle on the blasted surface and press the base of the gauge-holder firmly against the
steel. Do not drag the instrument.
7. Read the peak-valley value.
8. Make 10 measurements on each desired location and determine the mean as being the profile of the
surface.
5.2 Measuring Thickness
1. Press the On/Off button to switch the gauge on.
2. Check if the right tip is chosen. (the round tip is suitable for measuring thickness)
3. Choose parameter by pressing the IN/MM button.
4. Place the needle of the gauge on the flat glass specimen (zero plate) and press the gauge with the
holder down until the base of the holder stands firmly on the zero plate.
5. Press the ZERO button to make the instrument read zero.
6. Gently remove a piece of paint with a diameter of 8mm. from the surface. Try to remove the paint
without damaging the underground material.
7. Place the needle on the removed paint. Make sure the aluminium footing stands on the painted area.
8. The Coating thickness appears on the display.
6CHANGING TIPS
Step 1
Two tips are supplied.
The sharp needle tip is
suitable for measuring
roughness, the round
one for thickness.
Step 2
Take the tip between
two fingers and turn
anti-clockwise until it is
loose. If the tip stays
stuck, go to step 2a.
Step 2a
Only when loosening the tip
anti-clockwise by hand fails,
a pair of tongs may be used
GENTLY. Make sure the tip
remains undamaged.
Step 3
Turn the new tip
clockwise until it’s
stuck.
Step 4
The tips have been changed.
Don’t forget to store the tip
that’s not in use.

7BATTERY REPLACEMENT
If the display blinks it’s necessary to replace the battery. The battery compartment lid is the grey cap on top of
the gauge. Remove it by lifting it with a small screw driver.
Replace the LR44 battery with its positive side facing upwards.
8CALIBRATIONS
We recommend annual calibration. You can send the instrument to the TQC Service department, together with
a completed RMA form. This form is available on www.tqc.eu under the Service-menu ; Repairs / Calibrations

The Surface Roughness Comparator comes in a sturdy leather wallet.
4PERFORM A MEASUREMENT
By placing the appropriate comparator (G for Grit, S for Shot) against a blast cleaned surface, the finish achieved
can be compared against the four sections of the comparator. It is then a simple matter to identify (by sight and
touch) the standard surface:
Fine grade equal to or above segment 1 but below segment 2
Medium grade equal to or above segment 2 but below segment 3
Coarse grade equal to or above segment 3 but below segment 4

4.1 installing the batteries
Hold the aluminium casing firmly in one hand and
turn the end cap in a counter clockwise direction
until fully unscrewed (see figure) Pull the end cap
away from the casing and this will reveal the battery
cartridge. Place each battery in turn within the
cartridge ensuring that the polarity marks (+ and -)
on the battery match that of the cartridge. With all
LD7290

batteries installed replace the cartridge in to the casing and turn the end cap in a clockwise direction until fully
tightened. The flashlight is now ready to use.
IMPORTANT: please make sure the batteries are installed correctly otherwise battery damage may occur,
possibly resulting in a explosion. Never try to recharge batteries or use new and used batteries together. Always
change all the batteries at the same time and only use high quality ones. Be careful not to touch the gold
contacts at the end of the battery cartridge or rest them against anything conductive as this could cause short
circuit. If you do not intend to use the flashlight for a long period of time, remove the batteries to prevent them
leaking and damaging the flashlight.
4.2 operating the flashlight
To switch on the flashlight simply press the end cap switch until it engages, then release. To switch the
flashlight off, press the end cap switch once again until it disengages, then release.
