GENERAL OPERATION PRINCIPLE
There are four operation methods for this unit:
•
Manual Operation
•
Presets
•
Timed Program
•
PC Interface Mode.
•
The large Liquid Crystal Display will guide you through the various operations/procedures interactively once you understand the operation principle.
There are four Dual Function Control Keys for various operation modes and input states of the unit.
To change/set operation mode
(output on /off, key lock & etc.),
in most cases you need two Dual Function keys to complete the operation.
To change input values of various settings (voltage, current, preset number, cycles, time period & etc.), use the
ENTER
key to get ready and confirm the new settings.
Liquid Crystal Display
The back-lit display shows both the preset and the actual voltage, current levels at the output terminals; and status of constant current (
CC
) or constant voltage (
CV
) mode. Be
aware of new symbols appearing on the display while inputting. They will guide you and remind you of the correct procedure.
Example:
Inputting values of various settings
When a new setting (voltage, current, time periods & etc.) is ready for inputting, the symbol for the related setting will appear on the display. After you key in the required value,
always follow by pressing
ENTER
to confirm or to complete the operation.
Presets and Timed Subprograms
This unit has the capacity to store 10 programs.
Program 1 to 9 is for nine sets of Presets of voltage and current.
The program 0 is reserved for the 20 timed subprograms; each is capable of storing 1 second to 99-minute operation period with its preset voltage and current levels.
The timed subprograms can be set to operate repeatedly in sequence from 1 to 256 cycles or indefinitely.
