Pulse Mode
Pulse mode loading is available in three modes of operation (Constant Current, Constant
Resistance and Constant Power). Use the following steps when operating in pulse mode:
Manual Pulse ModeOperation
To manually operate the Dynaload, use the following procedure:
(1)Use the CI, CP CR button to set the baseline current, power, or resistance respectively.
(2)Use the FREQ button to set the frequency.
(3)Use the DUTY CYCLE button to set the duty cycle. For applications that require the
period to be set, the Time
HI and Time
LO functions should be used. The Time HI function
will set the time that the pulse remains at the peak setting. The Time
LO
function will set the
time that the pulse remains at the baseline setting.
(4)Use the PEAK button to set the amplitude of the pulse.
(5)Use the RUN button to initiate pulse loading. Press RUN a second time to turn pulse off..
It is recommended to monitor the current sample output with an oscilloscope (No earth
ground) to observe the actual current amplitude and waveform. If waveforms other than
square waves are required, this can be accomplished by programming the loads using an
external analog program source (refer to the
Remote Programming
section that follows).
