7. OPERATING INSTRUCTIONS
7.1 DC Voltage measurement
(1) Connect the red test lead to the “V.Ω.mA” jack and the black lead to the “COM” jack.
(2) Set rotary switch at desired DCV position. If the voltage to be measured is not
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.
