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

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:

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.

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.

Constant power mode

In constant power mode, the DC load will cause a constant power to be dissipated in the load. To

set up the DC Load to operate in constant power mode and in the steady state condition, use the

following keystrokes:
