For preheat cathode lamps that operate at an AC power frequency and without a starter circuit, the initial reading of each cathode resistance shall not be less than the minimum value specified in the relevant lamp parameter table. This resistance value includes the resistance of the wire. For preheat cathode lamps that operate at a high frequency, or lamps that can operate under high frequency conditions, when heated with the specified test current, the initial reading of each cathode resistance shall conform to the value specified in the relevant lamp parameter table. This resistance value includes the resistance of the wire. In addition, the average value of the resistance ratio R,/R. of the 10 cathode windings shall be within the range of 4.75 ± 0.5. R, is the cathode resistance when heated with the specified test current. R. is the cathode resistance at a temperature of 25 C ± 1°C. Both resistance values ​​do not include the wire resistance
