Correction By Zero AdjustmentCategory: PYROMETRY AND PYROMETERS Many pyrometers are supplied with a zero adjuster, by means of which the pointer can be set to any actual cold-junction temperature. If the cold junction of the thermo-couple is in a temperature of 100 deg.F., the pointer can be set to this point on the scale, and the readings of the instrument will be correct.
