OPERATING INSTRUCTIONS
DC
VOLTAGE MEASUREMENT
Vce=3V
1. Connect the red test lead to the " V.Q.
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.
OCCURRENT MEASUREMENT
1. Connectthe red test lead to the "V .Q.mA" jack and the
black
test lead to " COM " jaCk . (For measurements
between 200mA and
lOA , remove red lead to "1 OA " 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 connection.
AC VOLTAGE ME~SUREMENT
1. Connectthe red test lead to " V.Q. 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.
