7.10.4. Check of a combination of devices

The combination of devices is checked according to specifications for delivery at the stand by means of the special equipment (the generator of impulses, the stabilized power supply, shop of resistance, etc.). Help data for check of devices (at supply voltage 13,5±5 B and temperature of 23±3 °C) are provided in tab. 7.8, 7.9, 7.10, 7.11.
