Once the load tries to draw more than 0.3 amperes, however, the
supply holds the current to 0.3 amperes (unless OCP is on) and
allows the voltage level to vary accordingly. The power supply then
indicates C.C. on the display.
Setting Voltage and Current Steps
The CURRENT and VOLTS (step up) and (step down) arrow
keys allow you to make minor adjustments to the current and voltage
settings.
The STEP SET function determines the amount that the arrow keys
increment or decrement the setting when you press them.
Press STEP SET
→
VOLTS SET
→
(number)
→
(return ) to set
the amount of each voltage step increment and decrement.
Press STEP SET
→
CURRENT SET
→
(number)
→
(return ) to
set the amount of each current step increment and decrement.
NOTE
. The power supplies permit voltage steps up to 2.000 V and
current steps up to 0.200 A.
Example: Set voltage steps to 0.5 V and current steps to 0.1 A.
1. Set voltage steps to 0.5 V:
STEP SET
→
VOLTS SET
→
.5
→
(return )
2. Set current steps to 0.1 A:
STEP SET
→
CURRENT SET
→
.1
→
(return )
Press VOLTS to increase (and press VOLTS to decrease) the
voltage limit by steps of 0.5 V.
Press CURRENT to increase (and press CURRENT to
decrease) the current limit by steps of 0.1 A.
Press and hold the arrow key to increase the selection speed.
