Store Operation
To save the load
’s settings to a register (internal memory), press the Shift and A
(Save) keys. The A B C D LEDs will blink together.
Press the A or B or C View or D Mode keys to save the settings to non volatile
memory. Pressing A will store to A location. B to B location. C to C location. D to D
location. Hence, users can save up to four settings in each group. Note you may do
this for any of the 40 different groups assigned in the previous paragraph (Choose
Storage Group). Each settings can store two parameters: The mode of operation (i.e.
CC, CV, CR) and the values set for that mode.
Recall Operation
Press the
Shift
and
B
(Recall) keys. The Recall LED will turn on, which means
you may recall settings from the currently-chosen group. Press the
A
or
B
or
C View
or
D Mode
keys to recall the desired setting. When the Recall LED is lit,
the other keys are disabled. To exit the recall state, press the
(Recall) keys again.
Short
Shift
and
B
When the
Shift
+
On/Off
keys are pressed, the load simulates a short circuit. In CC
and CR modes, the maximum short-circuit current value is 1.2 times the current
range. In CV mode, the short-circuit current is the same as setting the CV
operation to 0.1 V. Note that the short-circuit current in CV mode will be less than
the short-circuit current in CC or CR modes.
Current range switch (3/30 A)
The Shift and
D Mode
keys switch between the 3 A and 30 A ranges. The 30A
LED is lit when the load is on the 30 A range. The current resolution is 10 mA
for the 30 A range and 1 mA for the 3 A range.
Checking the set value
The electronic load usually displays the actual voltage and current values at the
load
’s terminals. To check the set value, press the
A
or
B
keys. The set
value display will blink, showing you the currently-set value. You can use the
knob to change it. It will stop blinking after 3 seconds and revert to the previous
display. You can also turn the knob to see the set value.
