The following graphs will help you determine if the absorber's load capacity vs. RPM curve is a suitable match for the engine to be tested.

"For better control, the engine being tested should not be at the extreme high or low range of the absorber's capacity."

CAUTION: These curves are for prop-shaft RPM and assume a full absorber. If you are running an inadequate water supply system, then you might not be able to reach these maximums.

WARNING: These are only the hydraulic limits for each absorber. They do not take into account any other mechanical limits imposed by the dynamometer's hardware.
