To obtain a more precise reading, you could remove the objects being tested from
the circuit when measuring.
When diode testing has been completed, disconnect the connection between the
testing leads and the circuit under test and remove testing leads from the input
terminals.
Set the rotary switch to . Diode measurement mode is a default or presss
SELECT to select measurement mode.
For forward voltage drop readings on any semiconductor component, place the
