Connect the red test lead to the " V Q MA " jack andthe black lead to the “ COM ” jack. 2. Set rotary switch at desired DCV position . If thevoltage to be measured is not known beforehand , setrange switch at the highest range position and thenreduce ti until satisfactory resolution is obtained. 3 . Connect test leads across the source or load beingmeasured. 4.Read voltage value on the LCD display along with thepolarity of the red lead connection. CURRENT MEASUREMENT 1 . Connect the red test lead to the " MA " jack andthe black test lead to " COM " jack ( Formeasurements between 200MA and 20A . remove redlead to " 20A " jack . 2 . Set the rotary switch at desired DCA position 3 . Open the circuit in which the current is to be measured and connect test leads in series with the circuit. 4 . Read current value on LCD display along with thepolarity of red lead connection. AC VOLTAGE MEASUREMENT 1.Connect the red test lead to " V . n " jack and theblack testlead to the COM " jack. 2 . Set the rotary switch at desired ACV position. 3 . Connect test leads across the source or load beingmeasured. 4 . Read voltage value on the LCD diaplay. RESISTANCE MEASUREMENT 1 . Connect the red test lead to " V . a " jack and blacktest lead to the " COM " jack . ( The polarity of red leadis positive " + " ). 2 . Set the rotary switch at desired " Q " range position . 3 . Connect test leads across the resistor to be measuredand read LCD diaplay. 4 . If the resistance being measured is connected to acircuit , turn off power and discharge all capacitorsbefore applying test probes . DIODE TEST 1 . Connect the red test lead to " V . Q " jack andthe blacktest lead to the " COM " jack ( The polarityof red leadis positive " + " , ) 2 . Set the rotary switch at " - + " position. 3 . Connect the red test lead to the anode of the diode tobe tested and the black test lead to the cathode of thediode . The approx , forward voltage drop of the diodewill be displayed . If the connection is reversed . Onlyfiaure " 1 " will be shown. TRANSISTOR TEST 1 . Setthe rotary switch at " HFE " position 2 . Determine whether the transistor under testing is NPNor PNP and locate the emitter , base and collectorleads . Insert the leads into proper holes ofthe HFEsocket on the front panel 3 . Read the approximate HFE value at the test conditionof base current 10 UA and Vce 3V. NOTE : To avoid electrical shock . remove test leads from measurementcrcuits before testing a transistor . AUDIBLE CONTINUITY TEST 1 . Connect red test lead to " VO" blackest lead to “ COM ” . 2 . Set range swith to " . ) ) " Position. 3 . Connect test leads to two points of circuit to be tested . Ifcontinuity exists , built-in buzzer will sound. MEASURING TEMPERATURE 1 . Set the rotary switch at TEMP Position and theLCD display will show the current environmenttemperature. 2 . Connect the K type thermoelectric couple to vQ MAC " and " COM " jacks . 3 . The display will read Temperature Vatuet. MEASURING FREQUENCY 1 . Connect the black test lead to the COM jack and thered test lead to the Va Hz jack . 2 . Set the rotary switch at KHZ position and connect testleads across the source or load under measruement . NOTE : 1 . Reading is possible at input voltages above 10vrmsbut the accuracy is not guaranteed. 2 . In noisy environment , it is preferable to use shieldcable for measuring small signal. MEASURING CAPACITANCE 1 . Set the rotary switch at desired F position . 2 . Before inserting capacitor under measurement intocapacitance testing socket . be sure that the capacitor hasbeen discharged fully . 3 . When measuri
