Setup the Power Supply
The SE-9656 TUNABLE DC (Constant Cur-
rent) POWER SUPPLY supplies power to the
pen-type mercury lamp and the electromagnet
(SE-9655). The output for the mercury lamp is
1500 V (volts) AC (alternating current) with a
maximum current of 145 mA (milliamperes).
The output for the electromagnet is controlled
by the Current Adjustment Knob and the maxi-
mum output is 36 V.
•
NOTE: The electromagnet has a maximum
input current of 6 A and a maximum mag-
netic intensity of 1.2 T (tesla).
1. Check the LINE VOLTS setting on the
back of the Power Supply. Select the right
setting based on your AC voltage.
2. Connect the power cord to the AC POWER
CORD port. Plug the cord into a grounded
AC electrical outlet.
NOTE: The power supply fuse is located in a
plastic tray in the top part of the AC POWER
CORD port. The tray also holds a spare fuse.
Before opening the fuse tray, disconnect the
power cord. Always replace a fuse with a new
fuse of the same type (Fuse Type 250 V T5A).
•
Power Switch: Turns the power in the instrument ON or OFF.
•
Current Adjustment Knob: Sets the current through the electromagnet.
•
Amperemeter: Displays the current.
Insert the Mercury Lamp into the Electromagnet
CAUTION: The next step involves handling the pen type mercury lamp. Do not touch the glass envelope of
the mercury lamp. Oil and moisture from your fingers will degrade the lamp’s performance.
1. Insert the pen type mercury lamp into the holder between the poles of the electromagnet. The glass envelope should be
centered between the pole pieces.
