4.1
Ω
test
1. Plug the test leads into COM and + sockets.
2. Place the range selector to a prescribed range position.
3. Short the test leads and turn 0
Ω
ADJ to set the pointer to zero position.
4. Make sure that there is no voltage across the circuit to be tested.
5. Connect the test leads to the tested resistor and read the scale in accordance
with the reference table.
4.2 DCV test
1. Plug the red test lead into the + socket and the black one into the - COM.
2. Set the range selector to a selected DCV range position.
3. Connect the red test lead to the positive polarity of the circuit tested and the
black one to the negative.
4. Read the DCV.A scale referring the reference table.
4.3 ACV test
1. Plug the red test lead into the + socket and the black into the - COM socket.
2. Set the range selector to a chosen ACV range position.
3. Connect the test leads to the circuit being tested regardless of the polarities.
4. Read ACV scale with the reference table.
4.4 DCA test
1. Place the red test lead into the + socket and the black in the - COM.
2. Set the range selector at a selected DCA range position.
3. Connect the red test lead to the positive polarity of the circuit tested and the
black into the negative.
4. Read the DCV.A scale converted with the reference table.
4.5 ACV test on output terminal
1. Plug the red test lead into the OUTPUT socket and the black one into the -
COM.
2. Set the range selector at the selected range position. Connect the test leads to
the circuit to be tested and read the scale in the same manner as ACV test. Such
a measurement is made to block the DC voltage which is present in the same
circuit and must be cut out so that AC voltage can be read alone.
4.6 Iceo transistor test
