WR-25 Instruction Manual Normally, barometric pressure is the only item that needs to be recalibrated (adjusting for altitude). The proper local barometric pressure can be obtained from the local news. Set the barometric pressure reading you obtained from the local media by using the calibration mode function. Temperature If for some reason you suspect that the temperature is not calibrated properly, use a quality bulb thermometer with which to calibrate.
