Assure equipment is configured to be operated safely. Shaft/fan
calibration requires movement in associated equipment and
revolution counting. Flow calibration requires liquid dispensing,
catching, and measurement.

system is in a safe state. Start the monitor calibration by selecting the Enter
key. The Start symbol (triangle) will change to a Stop symbol (square).
Activate the shaft, fan, or flow. Count the revolutions (shaft/fan) or catch
liquid (flow) while the monitor measures pulses. Deactivate the shaft, fan, or
flow. Stop the monitor calibration by selecting the Enter key again. Highlight
the revolutions or liquid level window. Select the Enter key. Enter the
