Setting How the Instrument Displays Measurement Results (Enabling/Disabling Deviation Measurement Mode)

You can have the instrument display measurement results as absolute values or as deviations relative to the reference value (deviation measurement mode). You can change this setting for each of the measurement parameters 1 through 4. In deviation mode, you can set the instrument to display deviations as they are (Deviation mode) or as percentages relative to the reference value (% Dev. mode).

How the instrument displays measurement results differs according to the modes, as summarized in the table below.

where Meas and Ref mean the following:

Ref: Reference value (Display > Setup Prmtr Display > Parameter [1-4] > Reference)

When you are testing DUTs while using the bin sorting function, the bin sorting performs regardless of deviation measurement mode settings. However, the instrument displays measurement results according to the deviation measurement mode.

Follow these steps to set the deviation measurement mode.

Press Display > Setup Prmtr Display.
Select the desired parameter label (Parameter 1 to Parameter 4) from the softkey menu, and the deviation setup softkey menu for the selected label appear along with fixed MSD softkey menu.
Select Math Mode softkey menu to select the mode:

Softkey Label	Deviation measurement mode
Math Mode [OFF]	OFF
Math Mode [Deviation]	ON (absolute deviation mode)
Math Mode [% Dev]	ON (percent deviation mode)

Click the Data -> Reference softkey menu to set the data relative to the reference value. Click the softkey again to change the reference value.
Select the Reference softkey menu to manually enter the reference value when you select Deviation or % Dev.
