5. Connect test leads to device or circuit bcing measured.
Turn on power to device or circuit bcing measured.
Voltage value wili appear on Digital Display aiong with
the voltage polarity.
DC Current Measurement
1.. Red lead to "mA" jack for measurcrncr)ts rrp to 2 Amps,
Black lead to "COM" jack.
For measuremenb between 2 Amps and l0 Amps, connect
red lead to "l0A" jack.
POWER/FUNCTION switch to "I)C ()", rnd RANGE
switch to desired "A'' position.
Open the circuit to be measured, and conncct test leads
IN SERIES with the ioad in which currcnt is to be
measured.
Read current value on Digital Display.
AC Voltage Measurements
L. Red lead to "V-s}", Black lead to "COM".
2. POWER/FUNCTION switch to "AC", and RANGE switch
to desired "V" position.
3. Read voltage vaiue on Digital Display.
Resistance Measurements
1. Red lead to "V. f,}", Black lead to "COM".
2. POWER/FUNCTION switch to "DC s2", and RANGE
switch to desired "OHM" position.
If the resistance being measured.is connected to a circuit,
turn off power and discharge all capacitors before
applying test prods,
Connect test leads to circuit being measured.
Read resisrance value on Digital Display.

Continuity Checks
1. Red lead ro ,,V. o,', Black lead to ,,COM,,.
2. POWER/FUNCTION switch to ,,DC A" , and RANGE
switch to Btzzer ( ,r|) ) position.
3. Connect test leads to the circuit under test.
4. Built-in buzzer sounds if the circuit under test is con_
tinuous.

Diode Tests
L. Red lead to ,,V.f,)',, Black iead to ,,COM".
2. POWER/FUNCTION switch to ,.DC 0,',, and RANGE
switch to the 2K,e ( +<- ) position.
3, Ifthe semiconductorjunction being measured is connected
, to a circuit, turn off power and discharge all capacitors.
4. Connect test leads to device.
5. In case of connection of forward (Red to anode, Black
to, cathode) a good diode shows a value. If the diode
under _test is defective, "000,' (shorted), o, ,,1,, (opend)
is displayed.
When the test leads are connected reverse (Red to
cathode, Black to anode), a good diode shows ,,1i'. Ifit is
defective, "000" or other figures are to be displaved.
