Performing The Test - Elcometer 506 Guia Del Usuario

5 ATTACHING THE GAUGE TO THE DOLLY (continued)
3 Rotate the crank handle clockwise to undertake the test - see
Section 6 "Performing the Test" for details.
When testing at height or on vertical surfaces, in order to prevent damage to the
surrounding coating or harm to the user, it may be necessary to use the
Magnetic Anchor Clamp accessory, part number T99923797. This connects to
the lanyard ring on the top of the actuator to prevent the actuator from falling
when the dolly is pulled from the substrate.

6 PERFORMING THE TEST

6.1 USING 20mm OR 50mm DOLLIES -
ANALOGUE PRESSURE GAUGE
When testing coatings on concrete using 50mm dollies, scoring of the
coating down to, or into, the surface of the concrete may be required.
1 Hold the gauge steady with one hand
and turn the crank handle clockwise
slowly and evenly to apply an
increasing force to the dolly and hence
stress to the coating.
The rate at which the force is applied

(the speed of rotation of the crank handle)
should be in accordance with the relevant
Standard.
Continue until either;
(a) the coating fails and the dolly is
removed from the surface
(destructive testing) or;
(b) the minimum specified pressure
value is reached (non-destructive
testing)
2 Record the pressure indicated by the position of the red drag
indicator (a), using either the 20mm or 50mm scale as
appropriate and unwind the crank handle and coarse adjustment
screw.
Do not exceed the maximum pressure as overloading could damage the gauge.
