Press the IN/MM soft key to toggle the display between inch and
millimeter units of measure. This does not alter the channel
configurations in the Channel setup screen. The ND 2100G calculates
the conversion from one unit of measure to another as a convenience
to the user.
Master menu items and screens
Master screens are used to calibrate the encoder datums or
transducer input channel ranges. The Master function is configured in
the Master setup screen to either calibrate datum D0 for encoders, or
calibrate datum D0 and the entire channel range for transducers.
Master screen for calibrating encoder datums
When the Master setup screen is configured to perform full
calibrations of transducer input channels (Master type set to Min-
Max), the full range of any channel input can be calibrated at any time
using the Master function Min and Max screens. Up to 18 range
calibration values can be stored for each ND 2100G transducer input
channel. Any of these groups can be quickly recalled and applied later.
Prior to applying, and after clearing a mastered channel
value, the ND 2100G machine zero is used as the absolute
datum.
Pressing the MASTER soft key brings up the Channel
Master screen for calibrating encoder datums.
Instructions for calibrating channel datums are provided
later in this chapter.
