known beforehand, set range switch at the highest range position and then
reduce it until satisfactory resolution is obtained.
(3)
Connect test leads across the source or load being measured.
(4)
Read voltage value on the LCD display along with the polarity of the red lead
connection.
7.2 DC Current measurement
(1)
Connect the red test lead to the "V.Ω.mA" jack and the black test lead to
"COM" jack. (For measurements between 200mA and 10A, remove red lead
to"10A" jack.)
(2)
Set the rotary switch at desired DCA position.
(3)
Open the circuit in which the current is to be measured, and connect test leads
in series with the circuit.
(4)
Read current value on LCD display along with the polarity of red lead con-
nection.
7.3 AC Voltage measurement
(1)
Connect the red test lead to "V.Ω. mA" jack and the black test lead to the
"COM" jack.
(2)
Set the rotary switch at desired ACV position.
(3)
Connect test leads across the source or load being measured.
(4)
Read voltage value on the LCD display.
7.4 Resistance measurement
(1)
Connect the red test lead to "V.Ω. mA" jack and black test lead to the "COM"
jack. (The polarity of red lead is positive "+".)
(2)
Set the rotary switch at desired "Ω" range position.
(3)
Connect test leads across the resistor to be measured and read LCD display.
(4)
If the resistance being measured is connected to a circuit, turn off power and
discharge all capacitors before applying test probes.
7.5 Diode test
(1)
Connect the red test lead to "V.Ω.mA" jack and the black test lead to the
"COM" jack (The polarity of red lead is positive "+".).
(2)
Set the rotary switch at
(3)
Connect the red test lead to the anode of the diode to be tested and the black
test lead to the cathode of the diode. The approx. forward voltage drop of the
diode will be displayed. If the connection is reversed, only figure "1" will be
shown.
