The resistance ranges are 20, 200, 2k, 20k, 200k, 2M, 20M, 200M and 2000M.To measure resistance, please connect the Meter as follows:Insert the red test clip into the terminal and the black test clip into COM terminal.Set the rotary switch to range.Connect the test clips across with the object being measured.The measured value shows on the display. 1.2.3.11Measurement OperationA. Measuring Resistance (see figure 3)(figure 3)When measuring at 20Ω and 200Ω range, the test clips can add 0.1 to 0.3Ω error to resistance. To obtain precise readings in low-resistance measurements, short circuit the input terminals beforehand and record the reading obtained (called this reading as X). (X) is the additional resistance from the test clips.Then use the equation:measured resistance value (Y) – (X) = precision readings of resistance.The Meter displays “1” when there is no input, for example, open circuit situation.For high resistance measurement (>1M Ω), it normally requires several seconds to obtain a stable reading.When resistance measurement has been completed,disconnect the connection between the testing clips and the circuit under test and remove the test clips from the input terminals of the Meter.l l l l 12NoteTo avoid damage to the Meter or to the equipment under test, disconnect circuit power and discharge all high-voltage capacitors before measuringcapacitance.The Meter’s capacitance ranges are:200pF, 2nF, 20nF,200nF, 2µF, 20µF, 200µF, 2mF and 20mF.To measure capacitance, connect the Meter as follows:Set the rotary switch to F measurement mode. If the value of capacitor to be measured is unknown, use the minimum measurement position 200pF and increase the range step by step until a satisfactory reading is obtained and the overload icon "1" is not showing.Insert the red test clip into the CAP + terminal and black test clip into the CAP – terminal. For small value capacitor measurement, insert the capacitor into the Small Value Capacitance Jack.When testing polarized capacitors, use the red test clip on the capacitor’s positive lead, and the black test clip on the capacitor’s negative lead. With non-polarized capacitors, either direction is acceptable.1.2.3.13B. Capacitance Measurement(see figure 4)(figure 4)Do not short the test clips to avoid the consumption of battery.To minimize the effect of capacitance stored in the test clips, the test clips should be as short as possible and use the Small Value Capacitance Jack when measuring small value of capacitance.When capacitance measurement has been completed,disconnect the connection between the test clips and the circuit under test and remove the test clips from the input terminals of the Meter.l l l When measuring small value capacitor, that is 200pF,2nF and 20nF, first open circuit the test clips or the Small Value Capacitance Jack, then turn the Capacitance Zero Adjustment Switch to adjust zero.The measured value shows on the display.4.5.14NoteTo avoid damage to the Meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors before measuring diodes and continuity.Testing DiodesUse the diode test to check diodes, transistors, and other semiconductor devices. The diode test sends a current through the semiconductor junction, and then measures the voltage drop across the junction. A good silicon junction drops between 0.5V and 0.8V.To test a diode out of a circuit, connect the Meter as follows:Insert the red test clip into the terminal and the black test clip into the COMterminal.Set the rotary switch to .For forward voltage drop readings on any semiconductor component, place the red test clip on the component’s anode and place the black test clip on the component’scathode.The display shows the diode forward voltage drop’s nearest value.1.2.3.15C. Diode and Continuity Test (see figure 5)(figure 5)In a circuit, a good diode should still produce a forward voltage drop reading of 0.5V to 0.8V; however, the reverse voltage drop reading can vary depending on the resistance of other pathways between the probe tips.Connect the test clips to the proper terminals as said above to avoid error display. The LCD will display “1”indicating open-circuit for wrong connection. The unit of diode is Volt (V), displaying the positive-connection voltage-drop value.When diode measurement has been completed,disconnect the connection between the test clips and the circuit under test and remove them from the input terminals of the Meter.●●●To test for continuity,connect the Meter as below:Insert the red test clip into the terminal and the black test clip into the COM terminal.Set the rotary switch to .Connect the test clips across with the object being measured.Buzzer beeps if it is less than or equal to 10Ω and buzzer will not beep if it is more than 100Ω.The Meter displays the value of the test resistance.The LCD displays “1” indicating the circuit being tested is open.When continuity test has been completed, disconnect the connection between the test clips and the circuit under test and remove them from the input terminals of the Meter.●●16NoteTesting for Continuity1.2.3.4.5.NoteTo measure transistor, set up the Meter as follows:Check that the transistor is PNP or NPN type.Insert the transistor to be measured to the corresponding Transistor Jack .The Meter displays the tested transistor’s nearest value.When transistor measurement has been completed,disconnect the connection between the test clips and the circuit under test and remove them from the input terminals of the Meter.l 17D.
