Operation
Power On
After the power supply is properly connected to the electrophoretic
cell(s), select the 10 range and set Voltage Select to the fully counter-
clockwise (minimum) position. Set the display switch to Volts and tum
on power using the Power switch. When "On," the red LED is illumi-
nated.
Select Voltage
Adjust the Voltage Select control to the desired output voltage. The
Select Control will increase the output voltage approximately 10 volts for
every incremental adjustment. The Lo/Hi range switch is set to the Hi
position whenever operating voltages above 140 volts are required.
Note
The overcurrent alarm will sound whenever maximum output
current (500mA) is exceeded. Should this occur, reduce the operating
voltage until the overcurrent alarm goes off.
The volts/milliamps display switch will display either volts to nearest volt
or milliamps to the nearest milliamp, depending on the switch setting.
This switch may be changed at any time without affecting the output.
Disconnection
When disconnecting the power supply from the electrophoretic cell, for
any reason, first turn off the power switch and confirm that the red LED
is no longer illuminated.
