5. Device, action principle, bodies of indication and device
control
5.1. The principle is put in a basis of operation of the device the
annex of control tension to a metal product and a covering with the
put electrolit and fixings of course of a current at electrolit
penetration to metal in places of violation of a continuity of a
covering.
5.2. Bodies of indication and control are shown on fig.1.
5.3. On/off the device occurs in long pressing of the button.
5.4. Mode change (9V; 67,5V; 90V) occurs in short pressing of the
button. The active mode (control tension) is displayed by the light-
emitting diode.
Indication of the chosen mode (at the left on the right):
- a green light-emitting diode –9V;
- a yellow light-emitting diode –67,5V;
- a red light-emitting diode –90V.

6. Marking and packing
6.1. The device symbol is put on the front panel of the device with a
manufacturer trademark;
6.2. Serial number is in the battery compartment.
7. Preparation for work
7.1. Place in a battery compartment, previously having taken it from
the case, 3 batteries of AA type.
7.2. To prepare water solution of electrolit, in following a proportion:
70 grams of dry electrolyte to the one water liter.
7.3. To execute cleaning of oxide films on a sponge installation site
on an electrode the holder and clamping platinum.
7.4. Fix a sponge on an electrode holder.
7.5. With the connecting cable No. 1 (plug to plug) connect an
electrode holder to "lamb" of red color on the device.
7.6 With the connect the cable No. 2 (plug to clip) to "lamb" of black
color on the device.
7.7. To turn on the device, long pressing the button. The indicator
corresponding to the chosen mode (control tension) will light. The
device will keep the last operating mode, before switching off.
7.8. To choose, short pressing of the button an operating mode
(control tension) 9V or 67,5V or 90V.

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.
