((2)Voltage Hysteresis

The tube is operated at 300 V with an anode current of 0.1

µA

for 5 minutes. The light is then removed from the tube and the supply voltage

is quickly increased to 800 V. After a minute, the supply voltage is then

reduced to the previous value and the tube is re-illuminated for a minute to

measure the variation.

(1)Light Hysteresis

The tube is operated at 750 V with an anode current of 1

µA for

5 minutes. The light is then removed from the tube for a minute. The tube is

then re-illuminated by the previous light level for a minute to measure the

variation.
