1. Setup CC Values
a. Set the main CC level to 1 amp, the transient CC level to 2 amps, and the slew rate to 0. 15 A/
µ
s. See examples
under Setting CC Values.
b. Turn on CC mode by pressing:
2. Set frequency to 5 kHz by pressing:
3. Set duty cycle to 25% by pressing:
(blue shift key) (shifted)
4. Turn on transient operation by pressing:
5. Note that the Tran annunciator is on.
Shorting The Input
The Multiple Electronic Load can simulate a short circuit across any input channel. The short circuit can be toggled on/off
across the selected input by pressing
.
When the input is shorted the message "SHORT ON" will be displayed. The short on/off change uses the slew rate setting
of the active mode and range. Turning the short off returns the input to the previously programmed values and returns the
display to the metering mode. Note that "INPUT OFF" takes precedence over "SHORT ON".
Pressing the Short On/Off key with certain user applications may cause damage to the equipment being
tested, which may result in personal injury. Contact your Agilent Sales and Service office if you need
to have the Short On/Off key disabled.
Resetting Latched Protection
Each module in the Multiple Electronic Load includes overvoltage "OV", overpower "OP", and overtemperature "OT"
protection features as well as a software overcurrent limit protection feature (remotely programmable only) that latch when
they are tripped. The protection shutdown "PS" and voltage fault "VF" conditions also latch when tripped. The
annunciator on the front panel goes on when any of the above features are tripped in any channel. To reset these protection
features, press
.
Note The condition that caused the protection feature to trip must be removed or it will trip again as soon as it
is reset. Also, if OT occurs, the module must have sufficiently cooled down in order for the
to
take effect.
