Fig 2 Fig 3

• Check the fibre head for wear; if necessary replace it. Connect the condenser as shown in the figure. One
side of the double plate, double throw switch (1) must be connected to the main, and the other side must be
connected to the condenser (2) and test bulb (3) in series.
• Put on the switch (1). If the bulb glows the condenser must be replaced by a new one.
• If the bulb is not glowing then the condenser is in proper condition.
