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.
