3.2.3 Using as a constant current power supply
• For safety, turn off the POWER switch when connect-
ing the load.
1. Check that the OUTPUT switch is turned off.
2. Turn on the POWER switch.
3. While pressing the LIMIT switch, preset the requested volt-
age by turning the VOLTAGE control knob.
• The LIMIT switch simply displays the present voltage and
current settings. It has no memory feature.
4. While pressing the LIMIT switch, preset the requested cur-
rent by turning the CURRENT control knob.
5. Turn on the OUTPUT switch.
If a load is connected, the "CC" LED lights up on the control
panel showing that the unit is in constant current mode.
• If no load is connected, or if the load current level is too low,
the unit shifts to constant voltage mode, the "CV" LED lights
up. For more information, see "2.5 CV power supply and CC
power supply".
• For the loads listed below in which sudden current
application is undesirable, follow procedure 1 to 3
above, then follow procedure 4 to 6 below.
a. Loads of unknown resistance
b. Loads whose resistance varies over a wide range
c. Loads of large inductance
4. Turn the CURRENT control knob fully counter-clockwise.
5. Turn on the OUTPUT switch.
6. Turn the CURRENT control knob slowly to increase current
gradually.
The "CC" LED lights up on the control panel to indicate that the
unit is in constant current mode.
