start of a test and then lower fully to reapply the load after a selected pre-heat period (Release
Time).
The MP1200M is required for automatic operation and is also recommended whenever high
loads are being used in a test. Weights are contained on the weight support platform that
swings-away automatically when in its raised position for easy cylinder cleaning.
