Linearization off. In this mode the display will relate directly to the electrical
input.
A 20VDC unit will show-20000 to 20000 on the 5 digit display.
Graphically, the input has a 1 to 1 correspondence to the display.
1 point Linearization:
In this mode the display relates indirectly to the electrical input.
Example 1, The 20VDC relates to a 0 to 35kv transformer.
A 20VDC unit will show 0 to 35000 on the 5 digit display.
Input tells the device that 20.000 electrical will correspond to 35000 on the dis-
play.
Notice that on 1 point linearization symmetry is assumed about zero, and in this
case, there is no zero offset. The display will show (EEE or -EEE) when the display
exceeds 35000 or goes below -5000.
Example 2, The 20VDC has a 5 volt offset at zero. A 20VDC unit will show
-15000 to 25000 on the 5 digit display.
We would tell the device that 0.000 electrical will correspond to 5.000 on the display.
Notice that on 1 point linearization symmetry is now assumed about the offset.
The display will show over-range (EEE or -EEE) when the display exceeds 25000
