Constant current mode
In constant current mode, the DC load will sink a constant current, regardless of the voltage at its
terminals. To set up the DC Load to operate in constant current mode and in the steady state
condition, use the following keystrokes:
Key Display
I-set If you press this key after powering up and there is no currently-
stored constant current value, you'll be prompted for the desired
current level. If there was a current value already stored, it will be
momentarily displayed and the instrument will be in CC mode. If
you wish to change the current setting, press I-set again. The OFF
annunciator will be displayed.
On/Off Turns the constant current load on. The CC annunciator will be on.
or △ ▽ Momentarily display the power level and the set current value.
On/Off Turns the load off.
To operate the DC Load in CC mode in a transient condition, see the Transient operation section.
To operate the DC Load in CC mode in a dynamic condition, see the Lists section.
Constant voltage mode
In constant voltage mode, the DC load will cause a constant voltage to appear at its terminals. To
set up the DC Load to operate in constant voltage mode and in the steady state condition, use the
following keystrokes:
Key Display
V-set If you press this key after powering up and there is no currently-
stored constant voltage value, you'll be prompted for the desired
voltage level. If there was a voltage value already stored, it will be
momentarily displayed and the instrument will be in CV mode. If
you wish to change the voltage setting, press V-set again. The
OFF annunciator will be displayed.
On/Off Turns the constant voltage load on. The CV annunciator will be
on.
or △ ▽ Momentarily display the power level and the set voltage value.
On/Off Turns the load off.
To operate the DC Load in CV mode in a transient condition, see the Transient operation section.
To operate the DC Load in CV mode in a dynamic condition, see the Lists section.
