?

I refined my test...
Instead of ramping the voltage with the knob. I basically set the voltage to 20V and the amperage to 2 amps. I connected the voltmeter in series with the bulb and performed a dynamic load test by opening and closing the circuit by touching the probe lead of the voltmeter to the output of the power supply... I also have the Fluke voltmeter set to peak amperage measurement and these are the results that I found.

With the 6012B set to 20V and 2A, upon closing the circuit the peak amps are 4 amps but quickly settles to 2 amps
With the 6024A set to 20V and 2 A, upon closing the circuit the peaks amps are about 2.5 but quickly settles to 2 amps.

The important observation here is the 6012B settles back to 2 amps, it seems the settle time is longer and the deviation is larger than the 6024A. Although these are two completely different supplies If anything I could be nit picking here on the 6012B for its regulation settle time and overshoot, which is why I wanted to see if someone else had a similar supply and could see if they could duplicate the same results to see if this is normal...

Thanks for the help
