 Select CONTINUITY function using the function selector switch.
 Set sub-function CONTINUITY with UP / DOWN keys.
 Enable and set the limit (optional).
 Connect the test leads to the instrument.
 Null the test lead resistance if required (see section 5.3.4 Nulling of test lead
resistance).
 Disconnect from the mains supply and discharge the item to be tested.
