OPERATING INSTRUCTIONSDC

VOLTAGEMEASUREMENT

1 . Connect the red test lead to the "V Q MA" andthe blalead to" COM" .

2. Set rotary switch at desired DCV position . If thevoltage to be measured is not known beforehand , senge switch at the highest range position and thenreduce ti until satisfactory resolution is obtained.

3 . Connect test leads across the source or load gmeasured.

4.Read voltage value on the LCD display awith thepolarity of the red lead connection.

CURRENT MEASUREMENT

1 . Connect the red test lead to the "MA" andthe blatest lead to "COM" Formeasurements between 200MA and 20A . remove redlead to "20A" .

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 awith thepolarity of red lead connection.

AC VOLTAGE MEASUREMENT

1.Connect the red test lead to "V . n" and theblatestlead to the COM ".

2 . Set the rotary switch at desired ACV position.

3 . Connect test leads across the source or load gmeasured.

4 . Read voltage value on the LCD diaplay.

RESISTANCE MEASUREMENT

1 . Connect the red test lead to "V . a" and blacktest lead to the "COM" . The polarity of red leadis positive "+" .

2 . Set the rotary switch at desired "Q" range position.

3 . Connect test leads across the to be measuredand read LCD diaplay.

4 . If the resistance g measured is connected to acircuit , turn off power and discharge all sbefore applying test probes.

TEST

1 . Connect the red test lead to "V . Q" andthe blacktest lead to the "COM" The polarityof red leadis positive "+" ,

2 . Set the rotary switch at " - +" position.

3 . Connect the red test lead to the anode of the tobe d and the blatest lead to the cathode of the . The approx , forward voltage drop of the will be displayed . If the connection is red . Onlyfiaure "1" will be shown.

NSISTOR TEST

1 . Setthe rotary switch at "HFE" position

2 . Determine whether the nsistor under testing is NPNor 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 sho. remove test leads from measurementcrcuits before testing a nsistor.

AUDIBLE CONTINUITY TEST

1 . Connect red test lead to "VO" blackest lead" COM".

2 . Set range swith to " . " Position.

3 . Connect test leads to two points of circuit to be d . Ifcontinuity exists , built-in 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 couple to vQ MAC "and" COM "s.

3 . The display will read Temperature Vatuet.

MEASURING FREQUENCY

1 . Connect the blatest lead to the COM and thered test lead to the Va Hz .

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 under measurement intocapacitance testing socket . be sure that the hasbeen discharged fully.

3 . When measuring s 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.
