4-2 AC Voltage Measurement
1). Connect red test lead to “ V-
Ω
-Hz “ terminal and black test lead
to “ COM “ terminal.
2). Set range switch to desired V range and set DC / AC push
switch to AC position.
3). Connect Test prods of test leads IN PARALLEL to the circuit
being measured.
4). Read the voltage value displayed on LCD.
NOTE : See DC voltage measurement NOTE.
4-3 DC Current Measurement
1). Connect red test lead to “mA“ Terminal for Current
measurements up to 200mA. (For measuring Current between
200mA to 20A, Connect red test lead to “20A“ terminal.) Connect
black test lead to “COM” terminal.
NOTE :
For measuring current between 10A to 20A, maximum
measuring time is 30 second.
2). Set range switch to desired A range and set DC / AC push
switch to DC position.
3). Cut the power to the circuit to be tested and Connect the
instrument IN SERIES with the circuit ; with the black test lead on
the negative “
－
“ side and the red lead on the positive “
＋
” side
being measured.
4). Apply power and read the current value displayed on LCD.
