How to Perform a 1-2 Plane with Prognosis Procedure
Perform the Reference Run
To begin the dynamic 2 plane balancing procedure:
• Start the machine and bring it up to its steady running speed.
• At the 2-Plane Balance Setup screen, press the Start function button (or an
Enter / Fire button). The Balancing Summary screen displays.

Again we see that the Balancing Summary screen initially appears empty, with only the
Initial Run (IR) item highlighted (as no balancing runs have yet been performed).
• To proceed with the balancing job, with the IR run highlighted, press the Goto
function button to go to the initial run data screen - or press an Enter / Fire button
(as prompted in the prompt area). The Initial Run screen displays.
• At first, there is no data on the Initial Run screen. Take this opportunity to make
sure your sensors and tachometer device are set up correctly. To capture initial
run data, press the screen’s Start function button (or an Enter / Fire button). The
Microlog initiates the reference run measurements for RPM, magnitude, and phase.
The Initial Run screen displays measurement results.
