Test Lead Connections.

For measurements, as a rule, the red lead is inserted in
the jack marked + and the black lead in the jack
marked —. The jack marked
the red lead connection for measurements on the DC 0.1
volt and 50 microampere ranges.
Before the test leads are connected to the circuit to
be measured, confirm the position of the selector
switch.
at a resistance or current range, the meter movement,
shunt resistor or rectifier can be permanently damaged.
