OPERATION
CAUTION! To avoid possible damage to the meter or to the equipment under test, follow these guidelines:
1. Disconnect circuit power and discharge all capacitors before testing resistance, diode or continuity.
2. Use the proper terminals, function and range for your measurements.
3. Before measuring current, check the meter's fuse and turn off the power to the circuit before connecting the
meter to the circuit.
4. Before rotating the rotary switch to change functions, disconnect test leads from the circuit under test.
5. Remove test leads from the meter before opening the meter case or the battery cover.
6. Do not touch let the test leads touch each other during measurement as this may cause a short circuit.
MULTIMETER
1. Display: The 3.5 digit LCD displays a max. reading of 1999.
2. Function/Range Switch: This dial can be used to select the desired function
and range as well as to turn the meter ON/OFF. Switch the dial to the OFF
position when not in use. This will extend the battery life.
3. mA/Ω Jack: Plug-in connector for the red test lead. This is used for testing
Diode, Continuity, Resistance and Current measurements.
4. COM Jack: Plug-in connector for the black (Negative) test lead.
5. V Jack: Plug-in connector for the red test lead. Used to test
voltage measurements.
MEASUREMENT INSTRUCTIONS
When making connections, connect the common test lead before you connect the live test lead. When you
disconnect test leads, disconnect the live test lead first.
Verify the meter is operating correctly by measuring a known voltage before use.
The multimeter accuracy is specified for a period of 1 year after calibration, at 18°C ~ 28°C with relative humidity up
to 75%. The tables following each measurement method displays the accuracy specifications in the following form:
±[(% of Reading)+(Number of Least Significant Digits)]
MEASURING DC VOLTAGE
CAUTION! The Digital Multimeter is a CAT II device. Measuring a DC voltage that exceeds 250 V will exceed the
safety limits of the device and could result in an electric shock to the user or damage to the meter.
1. Connect the black test lead to the COM Jack and the red test lead to the V Jack .
2. Set the range switch to desired DC range
the range switch to the highest range and then turn it down range by range until satisfactory resolution
is obtained.
3. Connect the test leads across the source or circuit to be measured.
4. The LCD will display the reading. The polarity indicated is for the red test lead.
NOTE: In the range 200mV, when the test leads are in an open circuit state, the display will show a random number
It is normal and does not affect measurement.
