OPERATING INSTRUCTIONSDC
VOLTAGEMEASUREMENT
1 . 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 measuring capacitors with shorter leads , a testingadapter is provided with the meter into the capacitancetesting socket on the front panel to continue measurements.
4 . When testing large capacitances , note that there will bea certain time lag before the final indication.
