CAUTION
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
If enabled, the instrument measures Dielectric Discharge (DD) when the
capacitance is in the range 5nF
