6.0 MAKING MEASUREMENT

WARNING

To avoid possible electric shock, instrument damage and/or equipment
damage, do not attempt to measure voltages higher than 1000V DC / 750V AC,
although readings may be obtained. Be careful not to touch any energized
conductors with any part of your body.

6.1 AC Voltage Measurement

Understanding AC Zero Input Behavior of Trms Meters

Unlike averaging meters, which can accurately measure only pure sine
waves, Trms meters accurately measure distorted waveforms. Calculating
Trms converters require a certain level of input voltage to make a
measurement. This is why AC voltage and current ranges are specified from
10% of range to 95% of range. Non-zero digits that are displayed on a Trms
meter when the test leads are open or are shorted are normal. They do not
affect the specified AC accuracy above 10% of range.

To measure AC Voltage, connect the Multimeter as follows:

1. Insert the red test lead into the 'VW' terminal & the black test lead into

the 'COM' terminal.

2. Set the rotary switch to ACV position for AC voltage measurement.

3. Connect the DEVICE UNDER TEST (DUT) to the leads. The measured

value will read on the display.

4. When measurements are completed, disconnect the test leads from

the DUT. Remove the test leads from the multimeter.

5. In each range, the Multimeter has an input impedance of 10MW shunted

by 30 pf approx.

6. Normally the Multimeter is in AUTO mode, if source to be measured is

unknown. Select highest range 750V AC by Range button,

7. Never apply voltage greater than the specified limit otherwise, the

Multimeter can be damaged beyond repair.

17

14

6.2 DC Voltage Measurement

Note: When range is selected and the test leads are open it shows some count

on display this is because of high input impedance of meter which does not
affect the specified accuracy

To measure DC Voltage, connect the Multimeter as follows:

1. Insert the red test lead into the 'VW' terminal & the black test lead into

the 'COM' terminal.

2. Set the rotary switch to DCV position for DC voltage measurement.

3. Connect the DEVICE UNDER TEST (DUT) to the leads. The measured

value will read on the display.

4. When measurements are completed, disconnect the test leads from

the DUT. Remove the test leads from the Multimeter.

In each range, the Multimeter has an input impedance of 10MW.

5. Normally the Multimeter is in AUTO mode. Select highest range 1000V

DC by Range button if the source, being measured is unknown.

6. Never apply voltage greater than the specified limit otherwise, the

Multimeter can be damaged beyond repair.

6.3 AC/DC VOLTAGE MEASUREMENT (mV)

To measure AC/DC Voltage in mV, connect the Multimeter as follows:

1. Insert the red test lead into the 'VW' terminal & the black test lead into the

'COM' terminal.

2. Set the rotary switch to mV position & press SELECT switch for DC/AC

measurement mode.

3. Connect the DEVICE UNDER TEST (DUT) to the test leads. The

measured value will read on the display.

4. When measurements are completed, disconnect the test leads from the

circuit under test. Remove the test leads from the instrument.

CAUTION: Never apply voltage more than the specified limit else, the DMM
may damage beyond repairs. If the source is unknown, select highest range on
the DMM.

15

Note: When range is selected and the test leads are open it may show
overload indication on display & Buzzer beeps, this is because of high input
impedance of meter which does not affect the specified accuracy.

6.4 RESISTANCE MEASUREMENT

To measure resistance, connect the meter as follows:

1. Insert the red test lead into the ‘VW’ terminal and the black test lead into

the ‘COM’ terminal.

2. Set the rotary switch to ‘W ’ position to measure resistance.

3. Connect the DEVICE UNDER TEST (DUT) to the test leads. The

measured value will read on the display.

4. Completely de-energize the DUT. Connect the test leads to the DUT (the

red test lead is positive with respect to the black test lead). ‘OL’ indicates
an over range condition. This will occur with the test leads open on all
resistance ranges. If over range occurs when taking a reading, switch to
the next highest range.

5. Do not measure resistance if "LOBAT'' is displayed otherwise it will give

erroneous reading.

The test leads can add 0.1W to 0.2W of error to resistance measurement on
600 W range. To obtain precision readings in low resistance measurement,
that is the range of 600W, short-circuit the input terminals by using test leads
press ‘REL’ button so that the error reading can be subtracted from
measurement. Now connect the low value resistance.

CONTINUITY MEASUREMENT

WARNING

To avoid damages to the Meter or to the device under test, disconnect circuit
power & discharge all the high-voltage capacitors before testing for continuity.

To test for continuity, connect the meter as follows:

1. Insert the red test lead into the ‘VW’ terminal and the black test lead into the

COM terminal.

16

2. Set the rotary switch to ‘ ’ range to measure continuity.

3. Press Select button till Symbol appears on the LCD.

4. The buzzer sounds, if the resistance of the circuit under test is less than

30W approx.

W

DIODE MEASUREMENT

WARNING

To avoid damages to the Multimeter or to the device under test, disconnect
circuit power and discharge all the high-voltage capacitors before testing diode.

To test a diode out of a circuit, connect the Meter as follows:

1. Insert the red test lead into the ‘VW’ terminal and the black test lead into the
COM terminal.

2. Set the rotary switch to W position. Select Diode function by SELECT
switch, the display should show symbol.

3. Connect the test leads across with the diode being tested.

4. If the diode is good, 0.700V approx. in case of silicon diode or 0.200V in
case of germanium diode will displayed. If the diode is short, “0.000” will
be displayed.

5. If the diode is open, “OL” is displayed in both directions.

6. Do not measure the diode when it is connected in any circuit.

Use 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 shows forward voltage drop of 0.7V.

CAPACITANCE MEASUREMENT

WARNING

To avoid damages to the Multimeter or to the device under test, disconnect circuit
power and discharge all the high-voltage capacitors before testing capacitance.
Use the DC Voltage function to confirm that the capacitor is discharged.

To measure capacitance, connect the meter as follows

1. Insert the red test lead into the VΩ terminal and the black test lead into the
COM terminal.

20

17

2. Set the rotary switch to the position and then by pressing
SELECT buttons till the (capacitance) function nF/uF Symbol is
displayed.

3. Connect the test leads across with the object being measured. The
measured value is read on the display.

line voltage it is likely that the Multimeter can show 100Hz this is due to the
band width (Refer Specifications).

6.6 CURRENT MEASUREMENT in mA:

Understanding AC Zero Input Behavior of Trms Meters

Unlike averaging meters, which can accurately measure only pure sine
waves, Trms meters accurately measure distorted waveforms. Calculating
Trms converters require a certain level of input voltage to make a
measurement. This is why AC voltage and current ranges are specified from
10% of range to 95% of range. Non-zero digits that are displayed on a Trms
meter when the test leads are open or are shorted are normal. They do not
affect the specified AC accuracy above 10% of range.

For current measurement in mA, connect the Multimeter as follows:

1. Insert the red test lead into the mA terminal and the black test lead into the
COM terminal.

2. Set the rotary switch to mA position.
