Operation
Before taking any measurements, read the Safety Information Section. Always examine the instrument for damage, contamination, and defects. Examine the test leads for cracked or frayed insulation. If any abnormal conditions exist, do not attempt to make any measurements.
Voltage Measurements:
1. Connect the red test lead to the “VΩ” jack and the black test lead to the “COM” jack.
2. Set the Function/Range switch to the desired Voltage type (AC or DC) and range. If the magnitude of voltage is not known, set the switch to the highest range and reduce until a satisfactory reading is obtained.
3. Connect the test leads to the device or circuit being measured.
4. For DC, a (-) sign is displayed for negative polarity; positive polarity is implied.
Current Measurements:
1. Set the Function/Range switch to the desired current.
2. For current measurements less than 200mA, connect the red test lead to the µA/mA jack and the black test lead to the COM jack.
3. For current measurements greater than 200mA, connect the red test lead to the 10A jack and the black test lead to the COM jack.
4. Remove power from the circuit under test and open the normal circuit path where the measurement is to be taken. Connect the meter in series with the circuit.
5. Apply power and read the value of the display.
Resistance Measurements:
1. Turn off any power to the resistor to be measured. Discharge all capacitors. Any voltage present during a resistance measurement will cause inaccurate readings and could damage the meter if exceeding the overload protection of 500VDC or AC.
2. Insert the BLACK and RED test leads into the COM and Ω input terminals respectively.
3. Select the desired ohms (Ω) range.
4. Connect the BLACK and RED test probe tips to the circuit or device under test, making sure it is de-energized first.
5. Open circuits will be displayed as an overload condition.
6. Test lead resistance can interfere when measuring low resistance readings and should be subtracted from resistance measurements for accuracy. Select the lowest resistance range and make the test leads short together. The display value is the test lead resistance to be subtracted.
Diode Tests:
1. Connect the red test lead to the “VΩ” jack and the black test lead to the “COM” jack.
2. Set the Function/Range switch to the “diode test” position.
3. Turn off power to the circuit under test.
4. Touch probes to the diode. A forward-voltage drop is about 0.6V (typical for a silicon diode).
5. Reverse probes. If the diode is good, “OL” is displayed. If the diode is shorted, “.000” or another number is displayed. If the diode is open, “OL” is displayed in both directions.
6. If the junction is measured in a circuit and a low reading is obtained with both lead connections, the junction may be shunted by a resistance of less than 1kΩ. In this case, the diode must be disconnected from the circuit for accurate testing.

Safety & Warnings
The following safety information must be observed to ensure maximum personal safety during the operation of the Mini-Pro® Digital Multimeter:
1. Always inspect the meter, test leads, and accessories for any sign of damage or abnormality before every use. Do not attempt to take any measurements if abnormal conditions exist, such as broken test leads, cracked cases, or a display not reading.
2. Do not expose the instrument to direct sunlight, extreme temperatures, or moisture.
3. Never ground yourself when taking electrical measurements. Avoid touching exposed metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body isolated from ground by using dry clothing, rubber shoes, rubber mats, or any approved insulating material.
4. Use caution when working with voltages above 40Vdc or 20Vac to avoid electric shock. Never exceed the maximum allowable input value of any function when taking a measurement. Refer to the specifications for maximum inputs.
5. Never touch exposed wiring, connections, or any live circuit when trying to take measurements.
6. When using the probes, keep your fingers behind the finger guards on the probes.
7. Measuring voltage that exceeds the limits of the multimeter may damage the meter and expose the operator to a shock hazard. Always recognize the meter voltage limits as stated on the front of the meter.
