current control with external
voltage or resistance.”
・On/Off with the external
contacts is selected. ・See page 81, “Output On/Off
with external contacts”.
・The channel output key is not
selected or an incorrect channel
is selected for output. ・See page 44, “How to output”.
・Keys are locked. ・See page 48, “How to disbale
panel operations”.
“OVP” is displayed
when the OUTPUT
key is pressed. ・The OVP value is too low. ・See page 53, “OVP/OCP
function”.
・The sensing wire(s) is/are
disconnected. ・See page 73, “Voltage Remote
Sensing”.
・The resistor is open in the
external resistance control mode. ・See page 78 , “Constant-
voltage control with external
voltage or resistance”.
“OCP” is displayed
when the OUTPUT
key is pressed. ・The OCP value is too low. See page 53, “OVP/OCP
function”.
Cannot raise the
current up to the set
current value. CP (constant-power) operation is
being used, or the CP value is too
low. See page 43, “How to set power”.
Output is unstable. Oscillating due to influences of
the load.
・Twist the load or sensing wires,
or change the wire layout.
・Connect a capacitor at the
output end of the power source
or the load end.
Output voltage does
not fall. The Hi-Ω function is activated. See page 55, “Hi-Ω function”.
