3. Adjustment and operation
3.1 Lamp adjustment for fluorescence observation
3.1.1 Connecting power
Set the main switch of the power supply unit to “I” (ON). It will stabilize in 5 to 10 minutes after ignition.
●
Some mercury burners may not ignite the first time the power is turned on due to variance in production,
and the safety mechanism in the starter in such a case. If this occurs, set the main switch to “1” (ON),
then press the starter reset switch on the front panel of the power supply and between 1 to 4 seconds are
required for igniting the burner. Repeat as necessary.
●
To avoid shortening the burner life, do not turn the burner off within 15 minutes after ignition.
● The burner cannot be re-ignited for about 10mimutes, that is, until the mercury vapor inside
it has cooled down and condenser to liquid.
● Ensure that the hour counter is reset to “000.00” after replacement of the burner. And you
can insert a thin object such as a mechanical pencil tip into the reset hole on the front panel
of the power supply unit to press the internal switch
