Control Process - NOVOTEST ED-3D Manual

Design and manufacture of devices and
systems for nondestructive testing
7.9. In case of a small charge of batteries the device will be switched
off.
7.10. After choosing of control tension the device come to a
measurement mode.
7.11. To check device functioning.
7.11.1. To moisten a sponge with electrolyte solution that it
completely became impregnated.
7.11.2. To short-circuit a contact surface of a sponge of an electrode
holder and a clip of the crocodile type of a connecting cable No. 2. In
case of normal functioning of the device the indicator of the chosen
control tension "will begin to blink" and there is a faltering sound
signal.
7.12. For monitoring procedure a clip of the crocodile type of a
connecting cable No. 2 to fix on a product, having provided its
electric contact to basis metal.

8. Control process

8.1. The surface of a controllable covering should be dry.
8.2. Moisten an electrode holder sponge in electrolyte solution.
8.3. Start scanning of a surface of a covering by a sponge. Speed of
scanning should provide constant wettability of a surface with
electrolyte solution.
8.4. When passing the moistened sponge over a place of violation of
continuity the indicator of control tension of the chosen mode lights
up and the faltering sound signal will be heard.
