CAUTION
 Timer information is displayed from the start of the measurement until the
completion of each step measurement
 A high-voltage warning symbol appears on the display during the
measurement to warn the operator of a potentially dangerous test voltage
 The value of the capacitance is measured during the final discharge of the
test object
