Sensor correction• This corrects the input value from the sensor.
When a sensor cannot be set at the exact location where measurement is desired, thesensor-measured temperature may deviate from the temperature in the measurement
location. When using multiple indicators, sometimes the measured temperatures do
not match due to differences in sensor accuracy or installation site.
In such a case, the temperature in the installation site can be adjusted to the desired
temperature by adjusting the sensor input value.

Input value can be corrected in [Sensor correction coefficient] and [Sensor correction] in Auxiliary
Function Setting Mode 1.
In [Sensor correction coefficient], set the slope of temperature change.
In [Sensor correction], set the difference between temperatures before correction and after correction.
PV after input correction is expressed by the following formula.
PV after input correction = Current PV x Sensor correction coefficient + (Sensor correction value)
The following shows an example of input value correction using ‘Sensor correction coefficient’ and‘Sensor correction value’.

Solution
How to check whether the input signal wire is
disconnected[DC voltage (0 to 5 V DC, 0 to 10 V DC)]If the input to the input terminal of this instrument
is 1 V DC, and if a value (converted value from
scaling high, low limit setting) corresponding to 1
V DC is indicated, the instrument is likely to be
operating normally, however, the input signal wire
may be disconnected.
[Direct current (0 to 20 mA DC)]If the input to the input terminal of this instrument
is 4 mA DC, and if a value (converted value from
scaling high, low limit setting) corresponding to 4
mA DC is indicated, the instrument is likely to be
operating normally, however, the input signal wire
may be disconnected.
Connect the input terminals of DC voltage andcurrent to the input terminals of this instrument
securely.

Select the sensor input and temperature unit (or ) correctly.
Set them to suitable values.

Use a sensor with appropriate specifications.
Use an ungrounded type sensor.
Keep the instrument clear of any potentiallydisruptive equipment.
Cancel the HOLD function by opening terminals
