To exit MAX MIN mode, press EXIT.Note: MAX MIN mode can only be used under MANUAL ranging mode.OPERATIONMeasuring Voltages To measure voltage, do the following:1. Insert the red test lead into the V terminal and the black test lead into the COMterminal.2. Set the range selector to Vor V or Hz % mV3. Connect the test leads across the object being measured.4. The measured value shows on the display.AC measurement displays the True RMS value.DC measurement displays the effective valueof sine wave (mean value response). When the ACV function is selected, you canpress the Yellow Button to view the AC DCTrue RMS value in the primary display. The BLUE button cycles among mVfrequency and duty cycle. Special care should be taken when measuringhigh voltage. When voltage measurement has beencompleted, disconnect the test leads from thecircuit under test and remove the test leads from the input terminals of the meter.Warning: To avoid personal injury, or damage to the meter from electrical shock,do not attempt to measure voltages higher than 1000V, although readings may beobtained.7

Measuring Current To measure AC or DC current proceed asfollows:1. Turn off power to the circuit. Discharge all highvoltage capacitors.2. Insert the red test lead into the mAµA or Aterminal and black test lead into the COMterminal.3. If you are using the A terminal, set the rangeselector to A . If you are using mAµA terminal,set the range selector to µA .4. DC measurement is default, press blue button toselect AC measurement.5. Open the circuit path to be tested. Touch the redtesting leads to the positive side of the break;touch the black probe to the negative side of the break. Reversing the leads willproduce a negative reading, but will not damage the meter.6. Turn on power to the circuit; then read the display. AC measurement displaysthe True RMS value. DC measurement displays the effective value of sine wave(mean value response).7. Turn off power to the circuit and discharge all high- voltage capacitors. Removethe meter and restore the circuit to normal operation.8. When the ACA function is selected, you can press the Yellow Button to view theAC DC True RMS value in the primary display.Note: The Blue Button is to choose AC or DC current. If the value to be measured is unknown, use the maximum measurement positionand reduce the range step by step until a satisfactory reading is obtained. When the measured current is below 5A, continuous measurement is allowed. When the measured current is between 5A-10A, continuous measurement 10secand more than 15 minutes must be allowed between measurements. When current measurement has been completed, disconnect the test leads fromthe circuit under test and remove test leads from the input terminals of the meter.Measuring Resistance To measure resistance, procede as follows:1. Insert the red test lead into the Ω terminal andthe black test lead into the COM terminal.Ω press BLUE2. Set the range selector tobutton to select Ω measurement mode.3. Connect the test leads across with the objectbeing measured.4. The measured value shows on the display.Note: The BLUE button cycles among resistance,continuity, and diode. The LCD displays OL indicating open-circuitor the tested resistor value is higher than themaximum range of the meter.8

When testing the resistance signal from the calibrator, it is necessary to press andhold the RANGE while turning on the meter to change the maximum display to4000 counts but the accuracy remains unchanged.When resistance measurement has been completed, disconnect the test leadsfrom the circuit under test and remove test leads from the input terminals of themeter.Testing for Continuity Turn off power to the circuit. Discharge all highvoltage capacitors. To test for continuity proceed as follows:1. Insert the red test lead into the Ω terminal andthe black lead into the COM terminal.Ω press BLUE2. Set the range selector tobutton to selectmeasurement mode andconnect the test leads across with the objectbeing tested.3. The beeper comes on continuously for opencircuits, and will sound for conditions of less than 50Ω.Note: The BLUE button cycles between resistance,continuity, and diode. When continuity measurement has been completed, disconnect the test leads fromthe circuit under test and remove test leads from the input terminals of the meter.Testing Diodes Turn off power to the circuit. Discharge all highvoltage capacitors. Use the diode test to check diodes, transistors,and other semiconductor devices. The diodetest sends a current through the semicondutorjunction, then measures the voltage drop acrossthe junction. A good silicon junction dropsbetween 0.5V and 0.8V. To test for continuity proceed as follows:1. Insert the red test lead into the Ω terminal andthe black lead into the COM terminal.Ω press BLUE2. Set the range selector tobutton to selectmeasurement mode andconnect the test leads across with the objectbeing tested.3. Place the red test lead on the component’s anode and place the black test lead onthe component’s cathode.Note: The BLUE button cycles between resistance, continuity, and diode. When continuity measurement has been completed, disconnect the test leads fromthe circuit under test and remove test leads from the input terminals of the meter.9

Measuring Capacitance To ensure accuracy, the meter will first internallydischarge the capacitor under test. DIS.C willshow on the display. Depending upon the sizeof the capacitor and the amount of dischargerequired, this process may take some time. To avoid damage to the meter or to theequipment under test, disconnect circuit powerand discharge all high-voltage capacitors beforemeasuring capacitance. Use the DC Voltage function to confirm that thecapacitor is discharged. To measure capacitance, proceed as follows:1. Insert the red test lead into theterminal andthe black lead into the COM terminal.2. Set the range selector tomeasurement mode, the meter may display a fixedreading which is a internal distributed capacitor value. For best accuracy whentesting capacitors less than 10nF, the internal distributed capacitor value should besubtracted from the reading.Note: To improve the measurement accuracy of small value capacitors(less than 10nF), press REL with the test leads open to subtract the residualcapacitance of the meter and leads. It is recommended that the short test clip leads be used for capacitancemeasurement. The LCD displays OL indicating the tested capacitor is shorted or it exceeds themaximum range. Capacitors larger than 400µF take longer time. The analogue bar graph shows thetime left before finishing the measurement. When capacitance measurement has been completed, disconnect the test leadsfrom the circuit under test and remove test leads from the input terminals of themeter.Measuring Frequency / Duty CycleTo measure frequency and duty cycle, proceed asfollows:1. Insert the red test lead into the Hz terminal andthe black test lead into the COM terminal.2. Set the range selector to %Hz or Hz % mVand press BLUE button to select the Hzmeasurement mode for frequency measurementor % for duty cycle measurement.3. Connect the test leads across the circuit beingmeasured.4. The measured value shows on the primarydisplay. When frequency measurement has beencompleted, disconnect the test leads from thecircuit under test and remove test leads from the input terminals of the meter.10

Short circuit the test leads to showthe room temperature. The meter is default toCelsius degree unit, you can change units bypress the BLUE button once you have selectedo othe temperature function.CF2. Insert the point contact temperature probe intothe right hand pair of meter terminals.3. Place the temperature probe onto the objectbeing measured.4. The measured value shows on the display afterseveral seconds. Nominal environmental temperature for usingthe meter is 18o 23o otherwise a false readingmay be obtained especially in testing low temperatures. The included point contact temperature probe can only be used with temperatureup to 230oC or 440oF. When temperature measurement has been completed, disconnect the temperatureprobe from the input terminals of the meter.4 20mA loop current as % readout This mode shows the mA measured value oroutput level on a 4-20mA scale. Connect the Meter as follows: Set the range selector to mA4-20mA % andpress BLUE button to select(4-20mA)% option. When the measured current is below 5A,continuous measurement is allowed. When the readings obtained is 4mA: the primary display shows LOat 4mA: the primary display shows 0%at 20mA: the primary display shows 100% 20mA: the primary display shows HI When loop curent measurement has beencompleted, disconnect the test leads from the circuit under test and remove testleads from the input terminals of the meter.11
