[Function]
Adds correction value to PV (measurement value).
[Sample Setting]
In case PV is displayed as 90°Cin an environment where the actual temperature is 100°C, PV can still be adjusted to
100°Cby zero-setting the PV correction to 10 (°C). [Computation formula = 90°C(before PV correction) + 10°C= 100°C]
※
Numerical formula for the combination of “PV compensation gain setting” and “Zero Setting of PV Correction” is the
following:
“(Before PV Correction x PV compensation gain setting) + Zero Setting of PV Correction = After PV Correction”
Caution:
1) Setting the gain of PV correction greater may cause instability of the measurement value.
2) Setting the gain of PV correction to less than x1 will change the range of display.
[Sample Setting]
If the input of K thermocouple is -199.9°C–999.9°C:
PV compensation gain setting
: x0.5 →
“-100.0°C–500.0°C”
PV compensation gain setting
: x0.1 →
“-20.0°C–100.0°C”
3) Setting the zero setting of PV correction to less than 0 will change the range of display.
[Sample Setting]
If the input of K thermocouple is -210°C–1382°C:
Zero setting of PV correction: +100°C
→
“-110°C–1382°C”
Zero setting of PV correction: -100°C
→
“-210°C–1282°C”
