The meter in the electric heater should be calibrated once a year to check whether the meter error exceeds the specified range. If there is, then internal cleaning of the gauge, or drying, should do the trick in cases. If not, please ask professional maintenance personnel for inspection and maintenance, and do not handle it without authorization, so as not to damage the instrument.
