2. Use the numeric keys to enter the correct password. The VFD displays as
follows and the digits are flashing.
3. Use the numeric keys to enter 2.5 and press [Enter] to confirm. The VFD
displays as follows. The setting will be finished after two seconds.
Note
The power supply defaults to be in CV mode. If the circuit current is limited by the setting
current, the output of the power supply will automatically switch to CC mode. The display
annunciators indicate the working mode of the power supply. If the CV status indicator lamp
is lit, it indicates the power supply functions in CV mode. If the CC status indicator lamp is lit,
it indicates the power supply functions in CC mode.
3.4 Saving and Recalling Operation
You can store up to 16 different output states in storage register locations (1 to
16). Each output state includes Constant voltage value, Constant current value
and Maximum output voltage value. When shipped from factory, storage
locations “1” through “16” are empty. You can recall the saved settings by Recall
function.
Step1. After you setting an output state (CV value, CC value and Maximum
voltage), press [Save] key.
Step2.Use the numeric keys 0 to 9 or ▲ and ▼ keys to select the memory
location (the range is 1 to 16) which you want to store in.
Step3. Press [Enter] to confirm the memory location.
Step4. Press [Recall] key.
Step5. Use numeric keys 0 to 9 or ▲ and ▼ keys to select the states which you
want to recall.
Step6. Press [Enter] key to confirm. Then the saved settings will come on.
3.5 Output On/Off Operation
[On/Off] key is used to control the output of power supply. When [On/Off] key is
lit, it represents output has been turned on. If [On/Off] key is dark, it indicates
that output is off. In output on mode, the indicator light CV or CC will be lit.
Note
Please ensure the power supply and DUT have been connected well and then press [On/Off]
key to turn the output on; otherwise, it may strike sparks.
Please check the status of current in SET whether it is zero; if it is set as zero, please modify
to non-zero value; if still no output, please connect ITECH directly.
