PV X-Y 2-POINT CORRECTION SETTING

Determine any two points within the input range (upper and lower limit), then convert to corrected value to the PUV of Input 1.

For Example)

When the PV of the product is;

90℃ indication but actual temp. is 100℃

310℃ indication but the actual temp. is 300℃

If these are to be corrected by 2-point Correction Setting;

PV before correction: PX 1 = 90℃, PX 2 = 310℃

PV after correction: PY 1 = 100℃, PX 2 = 300℃

PX 1 PV Before Correction Lower Limit Value Setting

Setting Range：Setting Range Lower Limit to (PX 2 － 1℃) or Setting Range Lower Limit to (PX 2 –1.0℃)

：Setting Range Lower Limit to (PX 2 – 10-digits)

Setting Units：1℃ or 0.1℃, 1-digit

PX 2 PV Before Correction Upper Limit Value Setting

Setting Range：(PX 1 + 1℃) to Setting Range Upper Limit , or (PX 1 + 1.0℃) to Setting Range Upper Limit

：(PX 1 + 10-digits) to Setting Range Upper Limit

Setting Units：1℃ or 0.1℃, 1-digit

PY 1 PV After Correction Lower Limit Value Setting

Setting Range：Setting Range Lower Limit to (PY 2 － 1℃) or Setting Range Lower Limit to (PY 2 –1.0℃)

：Setting Range Lower Limit to (PY 2 – 10-digits)

Setting Units：1℃ or 0.1℃, 1-digit

PY 2 PV After Correction Upper Limit Value Setting

Setting Range：(PY 1 + 1℃) to Setting Range Upper Limit , or (PY 1 + 1.0℃) to Setting Range Upper Limit

：(PY 1 + 10-digits) to Setting Range Upper Limit

Setting Units：1℃ or 0.1℃, 1-digit

NOTE: - As much as possible, set the difference in the value of Before Correction and After

Correction bigger within the realizable range. When the difference is small, the margin of

error might be bigger.

- When the slope of PX 1 and PX 2 (before correction) is set to 1 and when the slope after

Correction becomes less than 1, the indication range in each input type becomes narrow.
