power again.
8. V/I
CHECK key
This key is used to display the set voltage and set current.
The voltmeter displays the set voltage and the ammeter displays
the set current while the key is held.
NOTE: When this key is pressed, the minimum digit of the
voltmeter becomes 100 mV (or 10 mV on a model of
18 V rating).
9. VOLTAGE control
This control is used to set the voltage in constant-voltage
operation. It varies and sets the limit value of the output voltage.
10. CURRENT control
This control is used to set the current in constant-current
operation. It varies and sets the limit value of the output current.
11. Output terminal (+)
Positive (+) output is given through this terminal.
12. Output terminal (-)
Negative (-) output is given through this terminal.
13. GND terminal
This grounding terminal is connected with the frame. Connect
a shorting bar between the GND terminal and (+) or (-) output
terminal normally.
14. Shorting bar
The shorting bar is normally used to connect the GND terminal
and (+) or (-) output terminal.
