@ POWER switch
When turned on, the indicators POWER and either of CC and
CV light. The power switch is automatically cut off when pro-
tection (overvoltage/overcurrnt/temperature) has operated.
@) Voltmeter
Indicates the output voltage or the preset voltage.
(3) Ammeter
Indicates the output current or the preset current.
@ VOLTAGE
Control that presets voltage for constant-voltage operation.
Turn it clockwise to raise the output voltage.
© CURRENT 7
Control that presets current for constant-current operation.
Turn it clockwise to increases the output current.
©) CV indicator
Indicates during constant-voltage operation.
@ CC indicator
Indicates during constant-current operation.
OUTPUT indicator
Red LED indicates when the output is on. The preset voltage is
available at the output terminals when this indicator is on.
Q) OUTPUT swtich
Output switch (contactless) that turns on and off the output
electrically. When the output is on (.m=), the OUTPUT indicator
lights and the voltage the voltmeter is reading is output at
the output terminals and the ammeter reads the current.
qd) V/I CHECK
(@ OVP CHECK
(2 OVP adj. control
Semi-fixed adjustment control permitting to preset the over-
voltage protection level.
(3 Output terminal (+)
Positive output terminal (red).
(4. Output terminal (—)
Negative output terminal (white).
@ GND
Ground terminal connected to the frame. This is connected
also to the output terminal (—) normally.
(§ Voltmeter zero adjuster
Adjuster of the voltmeter zero point. (Not for D type)
(2) Ammeter zero adjsuter
Adjuster of the ammeter zero point. (Not for D type)
