use the product close to its maximum temperature. A quick check using an independent thermocouple and temperature indicator should be made from time to time to determine whether full calibration is required. Carbolite Gero can supply these items. Depending on the controller fitted, the controller instructions may contain calibration instructions. -
Page 21: Power Adjustment
Please note: it is not possible to use the cold resistance of the element as a measure of ageing as the cold resistance is not an accurate indicator of hot resistance. Hot resistance is used to calculate furnace power. See the controller instructions for how to adjust the controller. Always record the setting when first making an adjustment. -
