It would be easy to translate a constant load curve into a constant
current curve, using a computer based translation table for example.
The result would, for all practical purposes, be accurate enough to
compare to other testers constant current specs.
You will probably want a computer based logging anyhow, so the
translation could be automatically added to the logging procedure.
It is a bit of cheating, but the results would be just as reliable as
the constant current tests others make. We just need to translate the
measuring values from a constant load test into a constant current
The translation can be theoretically computed and/or achieved through
practical comparisons between constant current tests and constant load
