Error correction method for measuring temperature and actual temperature in the box a. Put a mercury thermometer (a mercury thermometer with a precision of 0.1 °C) into the working chamber, and the mercury end should be placed at the geometric center of the room; the reading of the mercury thermometer is the actual temperature.
b. Turn on the machine, when the device is running to a constant temperature state (about 1~2 hours), compare the difference between the actual temperature and the temperature displayed on the PV display. The difference (actual temperature-PV display value) is the measured value correction parameter pd needs to be modified. Value, ie:
Pb = original pb value + (actual temperature - PV display value)
c. Calculate the pb value input according to the above formula.
