4.4. ACV TEST

1. Set the function switch to the highest ACV

position.

2. Insert the test leads into COM (Black lead)

and "+" socket (Red lead)

3. Connect the test leads to the circuit being

tested, regardless of the polarities. (Fig.03)

4. Read ACV scale with the reference table.

Reset the function switch to successively

lower ACV positions to obtain a higher

resolution reading.

Do this test as the ACV TEST, but read the decibel scale with the

reference table of decibel not the ACV.

1. Set the function switch to the highest DCA

position.

2. Insert the test leads into COM (Black lead)

and "+" socket (Red lead)

3. Remove power from the circuit under test,

then open up the circuit at the point where

you wish to measure current. (Fig.04)

4. Read the DCV.A scale converted with the

reference table. Reset the function switch to

successively lower ACV positions to obtain a

higher resolution reading.

1. Set the function switch to the highest DCV

position.

2. Insert the test leads into COM (Black lead)

and "OUTPUT" socket (Red lead)

3. Connect the test leads to the circuit to be

tested and read the scale in the same

manner as DCV test. Reset the function

switch to successively lower ACV positions to

obtain a higher resolution reading.(Fig.05)

Note: 1. The voltmeter is connected in parallel. 2.

Such a measurement is made to block the DC

voltage which 1 presents in the same circuit and

must be cut so that AC voltage can be read alone.
