Operating Instructions
DC Voltage Measurement (DC V)
1. Set the function/range switch to the DC V position.
2. Insert the black (negative) test lead into the "COM" jack and the red (positive)
test lead into the V/
Ω
/F/ / jack. NOTE: The multimeter will be in auto-ranging.
3. Touch the test leads to the circuit or device being measured, and read the
voltage value, along with the voltage polarity on the LCD.
CAUTION: Never apply the voltage over 1000 V. Use
extreme
caution when
working with high voltage. Never connect test leads with circuit when changing
the position of function switch.
AC Voltage Measurement(ACV)
1. Set the function/range switch to the AC V position.
2. Insert the black (negative) test lead into the "COM" jack and the red (positive)
test lead into the V/
Ω
/F/ / jack. NOTE: The multimeter will be in auto-ranging.
3. Touch the test leads to the circuit or device being measured, and read the
voltage value on the LCD.
CAUTION: Never apply the voltage over 750 V. Use
extreme
caution when working
with high voltage. Never connect test leads with circuit when changing the position
of function switch.
DC Current Measurement (AC/DC)
1.Set the function/range switch to the AC/ DC position. and
Push the Select
pushbutton onceor twice, until “AC” appears in LCD
2. Insert the black (negative) test lead into the "COM" jack and the red (positive)
test lead into the mA/
µ
A TEMP jack. If the magnitude of value is unknown.
set the function/range switch to the highest range and reduce until desired
reading is oained. For current measurements from 400 mA to 10 A, insert
the red test lead into the 10 A jack. Set the function switch to10 A. NOTE:
The multimeter will be in auto-ranging.
3. Remove power from the circuit under test. Then open up the circuit at the point
where you wish to measure current.
4. Touch the black lead tips to the negative side of the circuit. Touch the red test
lead tips to the positive side of the circuit.
5. Apply power to the circuit.
6. The value and polarity of the current will appear on the LCD.
CAUTION: Never apply the voltage over 400 mA or 10 A to the corresponding
jack. Never connect test leads with circuit when changing the position of the
