4-4 AC 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 AC 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
of the circuit being measured.
4). Apply power and read the current value displayed on LCD.
4-5 Resistance Measurement
WARNING
Before taking any in-circuit resistance measurement remove
power from the circuit being tested and discharge all Capacitors.
1). Connect red test lead to “ V-
Ω
-Hz “ terminal and black test lead
to “ COM “ terminal.
2). Set range switch to desired
Ω
Range.
3). Connect the test leads to the circuit being measured and read the
resistance value displayed on LCD.
