• Fine Output Calibration
Using the Programming Unit (ITEM 19, 20)
ITEM 19 is for Zero, and ITEM 20 is for Span.
1) Turn the unit into Program mode (ITEM 01).
2) Apply simulated 0% input. Increase/decrease values
(default: 0%) at ITEM 19 until the output signal is cali-
brated to actual 0%.
3) Apply simulated 100% input. Increase/decrease value
(default: 100%) at ITEM 20 until the output signal is cali-
brated to actual 100%.
4) Apply simulated 0% input again and check 0% output.
5) When 0% value is changed, repeat the above procedure
2) – 4).
The 0% value may be shifted when the output span is
greater than the input span (gain > 1).
• Using Linearization Table
Please have the PU-2x Operation Manual ready at hand.
Max. 16 calibration points defined by sets of input and out-
put values can be programmed. Use only necessary number
of points, arranged in order from the smallest input value.
Enable use of the linearization table (ITEM 10: Pm-2:
curved) in order to activate the settings.
