| (10) The capacity of the condenser should be checked at a temperature of 45°C, and should fall within the limits .41 to .52 mf. It should also be ascertained that at this temperature, the condenser is still capable of holding a static charge for a time long enough to observe this on causing the condenser to discharge.
