Thank you for your purchase of this Elcometer 550 Non-Contact Uncured Powder Gauge. Welcome to

Elcometer.

Elcometer are world leaders in the design, manufacture and supply of inspection equipment for coatings

and concrete. Our products cover all aspects of coating inspection, from development through application

to post application inspection.

With the purchase of this product you now have access to the worldwide service and support network of

Elcometer. For more information visit our website at www.elcometer.com.

1 ABOUT THIS INSTRUMENT

The Elcometer 550 is designed to allow the user to determine the dry film thickness of powder before it has

been put in the oven to cure. This not only allows the user to control the dry film thickness of their product

but also to minimise the wastage of expensive powder. Using an ultrasonic method the gauge does not

require that the surface be disturbed to take a measurement, ensuring an ideal finish.

Measurements are taken by holding the gauge at the correct distance and angle from the powder coated

part. The large colour display on the gauge body as well as another smaller LED display on the sensor gun

help guide the user into the correct position.

To maximise the benefits of your new Elcometer 550 Non-Contact Uncured Powder Gauge, please take

some time to read these Operating Instructions. Do not hesitate to contact Elcometer or your Elcometer

supplier if you have any questions.

2 GETTING STARTED

2.1 CHARGING THE BATTERY

Your gauge features an internal rechargeable battery. The charger input is located on the bottom of the

gauge beneath the protective cover. (See image on page op pagina 5.)

Before using your gauge for the first time be sure to charge the battery for 3 hours. Subsequent charging

should take no more than 1.5 hours and provide up to 7 hours use of the gauge.

Note: Batteries must be disposed of carefully to avoid environmental contamination. Please consult your

local Environmental Authority for information on disposal in your region.

Do not dispose of any batteries in fire.

2.2 SWITCHING ON/OFF

To switch on, press and hold the button for three seconds. The gauge will make a sound confirming

that it has switched on and the main menu will be displayed. The gauge may also be switched on by using

the "Go" button on the sensor gun in the same way.

To switch off, press and hold the button for 3 seconds. The gauge will make a sound confirming that

it has switched off.

2.5 TAKING A MEASUREMENT

2.5.1 Zeroing the gauge

Each Elcometer 550 Non-Contact Uncured Powder Gauge is individually calibrated at the factory. To

ensure the highest level of measurement accuracy the Elcometer 550 should be zeroed by the user, before

use, to take into consideration the varying environmental conditions.

To zero the gauge:

• Take the circular zero reference block from the case and check that the inside is clean and free from

dust

• Position the sensor gun vertically so that the top of the measurement head is pointing vertically

upwards and place the zero reference block over the top

Note: The zero reference block fits loosely on to the sensor gun and will fall off if not held vertically.

DISCONTINUED

• Holding the sensor by the handle, not the sensor barrel,

switch the gauge on and select from the main menu

• The gauge will start taking measurements and once

complete ‘OK’ should be displayed

• The gauge is now ready for measurements. Place the

zero reference block back in the case making sure that the

internal surfaces are facing down to keep it free from dust

and powder contamination

Note: In the unlikely event of a zeroing failure an error code will be displayed. Check the zero reference

block for contamination or damage and retry. In the case of multiple failures please contact your nearest

Elcometer representative.

2.5.2 Positioning the Sensor Gun to take a reading

The Elcometer 550 is a non-contact powder thickness gauge which uses a focused ultrasonic measurement

method. In order for the gauge to collect the data required to calculate a reading, the sensor gun has to be

at the correct distance away from, and perpendicular to, the powder coated surface.

To achieve the correct positioning the Elcometer 550 Non-Contact Uncured Powder Gauge provides the

user with both visual and acoustic cues on the sensor gun and on the instrument’s colour display. Once the

gauge is in the correct position the gauge starts to automatically collect data. The diagrams below illustrate

how to use the visual indicators on the gauge and gun to achieve the correct measurement position.
