The microcomputer’s GND line which
control the thermistor,etc. share the
same line of 330V line. This circuit is
non-insulation type. Do not touch
the control circuit components as it
may result in electrical shock hazard.
Do not earth osilloscope etc. during
measurement, as it may result in
damage.
