GENERAL INSTRUCTIONS

This multimeter has been designed according to IEC1010 standards for
electronic measuring instruments with an over-voltage category (CAT II 1000V,
CAT III 600V) and pollution level 2.
To get the best service from this instrument, read carefully this user manual and
respect the detailed safety precautions.

1.1. Precautionary safety measures

Preliminary

• When using this multimeter, the user must observe all normal safety rules
concerning:

- Protection against the dangers of electric current.

- Protection of the multimeter against misuse.

• For your own safety, only use the test probes supplied with the meter provided.
Before use, check the meter and probes are in good condition.

During use

• If the meter is used near noise generating equipment, be aware that the
display may become unstable or indicate large errors.

• Use EXTREME CAUTION when working around bare conductors or bus bars.

• DO NOT operate the meter around explosive gas, vapour, or dust.

• Verify a meters operation by measuring a known voltage and DO NOT use the
meter if it operates abnormally. Protection may be impaired. When in doubt,
have the meter serviced.

• Use the proper terminals, function, and range for your measurements.

• When the range of the value to be measured is unknown beforehand, ALWAYS
set the range dial at the highest position or autoranging mode.

• NEVER exceed the protection limit values indicated in the specifications for
each range of measurement.

• DO NOT touch unused terminals when meter is linked to a circuit.

• Be careful when working with voltages above 60V DC or 30V AC rms.

• When using the probes, keep your fingers behind the finger guards.

• When making connections, connect the common test lead before connecting
the live test lead; when disconnecting, disconnect the live test lead before
disconnecting the common test lead.

• Before changing functions, disconnect the test leads from the circuit under test.

• For all DC functions, including manual or auto range, to avoid the risk of shock
due to possible improper reading, verify the presence of any AC voltages by
first using the AC function. Then select a DC voltage range equal to or greater
than the AC range.

5163440K_Instructions.qxd 18/09/2009 10:31 Page 3

• Disconnect circuits power and discharge all high-voltage capacitors before
testing Resistance, Continuity, Diodes, or Capacitance.

• NEVER perform resistance or continuity measurements on live circuits.

• Before measuring current, check the meters fuse and turn off power to the
circuit before connecting the meter to the circuit.

• When carrying out measurements on TV or switching power circuits, always
remember that there may be high amplitude voltage pulses at the test points
which may damage the meter. Use of a TV filter will attenuate any such pulses.

• To avoid the wrong reading or even electric shocks, when the meter displays

, you must change the battery.

• Do not measure voltages above 600V in category III, or 1000V in Category II installations.

• When in REL mode, the 'REL' symbol is displayed. Caution must be used
because hazardous voltage may be present.

• Do not operate the meter with the case (or part of the case) has been removed.

• For continuous protection against fire, replace fuse ONLY with the specified
voltage and current ratings: F200mA/250V.

3.2 Measurement Functions
AC and DC Voltage measurement

To avoid electrical shock and/or damage to the multimeter, do not
attempt to take any voltage measurement that might exceeds
1000V DC or 1000V AC rms.

To avoid electrical shock and/or damage to the instrument, do not
apply more than 1000VDC or 1000VAC rms between the common
terminal and the earth ground.

The meters voltage ranges are 600.0mV, 6.000V, 60.00V, 600.0V and 1000V.
(AC 600.0mV range only exists in manual mode).
To measure ‘AC or DC’ voltage:

1. Set dial to the '

DDCCVV,, AACCVV orDDCCmmVV

' range.

2. Connect the black test lead to the

CCOOMM

and red test leads to the

VV

terminals

respectively.

3. Connect the test leads to the circuit being measured.

4. Read the displayed value. The polarity of red test lead connection will be
indicated when making a DCV measurement.

NNOOTTEE::

• An unstable display may occur especially at 600mV range, even though you do
not put test leads into input terminals, in this case, if an incorrect reading is
suspected, short the terminals in use to make the display return to zero.

• For better accuracy when measuring DC, offset from the AC voltage, measure
the AC voltage first.

EEXXTTRRAA NNOOTTEE::

• Select the AC voltage range, then manually select a DC voltage range equal
to or higher than the AC range. This improves the accuracy of the DC
measurement by ensuring that the input protection circuits are not activated.

Auto Range Digital Multimeter - USB Interface

Resistance measurement

To avoid electrical shock and/or damage to the instrument,
disconnect circuit power and discharge all high-voltage capacitors
before measuring resistance.

The meters resistance ranges are 600.0Ω, 6.000kΩ, 60.00kΩ, 600.0kΩ,

6.000MΩ and 60.00MΩ.
To measure resistance:

1. Set the dial to

ΩΩ

range.

2. Connect the black test lead to the

CCOOMM

and the red test lead to the

HHzz

ΩΩVV °°CC

terminals respectively.

3. Connect the test leads to the circuit being measured and read the displayed value.

TTiippss ffoorr mmeeaassuurriinngg rreessiissttaannccee::

• The measured value of a resistor in a circuit is often different from the
resistors rated value. This is because the meters test current flows through all
possible paths between probe tips.

• In order to ensure the best accuracy in measurement of low resistance,
short the test leads before measurement keeping the test probe resistance in
mind. This is necessary to subtract the resistance of the test leads from the
measured resistance.

• The resistance function can produce enough voltage to forward-bias silicon
diode or transistor junctions, causing them to conduct. To avoid this, DO NOT
use the 60MΩ range for in-circuit resistance measurements.

• On 60MΩ range, the meter may take a few seconds to stabilise reading. This
is normal for high resistance measuring.

• When the input is not connected, i.e. at open circuit, the figure 'OL' will be
displayed for the overrange condition.

5163440K_Instructions.qxd 18/09/2009 10:31 Page 11

12

Diode Test

To avoid electrical shock and/or damage to the instrument,
disconnect circuit power and discharge all high-voltage capacitors
before testing diodes.

To test a diode out of a circuit:

1. Set the dial to

ΩΩ

range.

2. Press the '

SSEELLEECCTT

' key once to activate (diode test) mode.

3. Connect the black test lead to the

CCOOMM

and red test lead to the

HHzz

ΩΩVV °°CC

terminals respectively.

4. For forward-bias readings on any semiconductor component, place the red test
lead on the components anode and place the black test lead on the
components cathode.

5. The meter will show the approx. forward voltage of the diode.

NNOOTTEE::

In a circuit, a good diode should still produce a forward bias reading of

0.5V to 0.8V; however, the reverse-bias reading can vary depending on the

resistance of other pathways between the probe tips.

Continuity Check

To avoid electrical shock and/or damage to the instrument,
disconnect circuit power and discharge all high-voltage capacitors
before testing for Continuity.

To test for continuity:

1. Set the dial to

ΩΩ

range.

2. Press the 'SELECT' key twice to activate (continuity check) mode.

3. Connect the black test lead to the

CCOOMM

and red test lead to the

HHzz

ΩΩVV °°CC

terminals respectively.

4. Connect the test leads to the resistance in the circuit being measured.

5. When the test lead to the circuit is below 50Ω, a continuous beeping will
indicate it.

NNOOTTEE::

Continuity test is available to check open/short of the circuit.

TTiippss ffoorr mmeeaassuurriinngg ccaappaacciittaannccee::

• The meter may take a few seconds to stabilise reading. This is normal for high
capacitance measuring.

• To improve the accuracy of measurements less than 60nF, subtract the
residual capacitance of the meter and leads.

• Below 600pF, the accuracy of measurements is unspecified.

Frequency and Duty Cycle measurement

Do not measure Frequency on high voltage (>1000V) to avoid
electrical shock hazard and/or damage to the instrument.

The meter can measure Frequency or Duty Cycle while making either an AC
Voltage or AC Current measurement.

Current measurement

To avoid damage to the meter or injury if the fuse blows, never
attempt an in-circuit current measurement where the open-circuit
potential to earth is greater than 250V.

To avoid damage to the meter, check the meters fuse before
proceeding. Use the proper terminals, function, and range for your
measurement. Never place the probes in parallel with a circuit or
component when the leads are plugged into the current terminals.

The multimeter's current ranges are 600.0µA, 6000µA, 60.00mA, 600.0mA,

6.000A and 10.00A.
To measure current:

SSEELLEECCTT

key to select '

DDCC AA

' or '

AACC AA

' measuring mode.

4. Connect the black test lead to the

CCOOMM

terminal and the red test leads to the

mmAA

terminal for a maximum of 600mA. For a maximum of 10A, move the red

test lead to the A terminal.

5. Break the circuit path to be tested, touch the black probe to the more negative
side of the break and touch the red probe to the more positive side of the
break. (Reversing the leads will give a negative reading, but will not damage
the meter.)

6. Turn power '

OONN

' to the circuit; then read the display. Be sure to note the
measurement units at the right side of the display (µA, mA or A).
When only the figure 'OL' displayed, it indicates overrange situation and the
higher range has to be selected.

7. Turn '

OOFFFF

' power to the circuit and discharge all high voltage capacitors.

Remove the meter and restore the circuit to normal operation.

MAINTENANCE

This section provides basic maintenance information, including fuse and battery
replacement instructions.
Do not attempt to repair or service your Meter unless you are qualified to do so
and have the relevant calibration, performance test, and service information.

6.1 General Maintenance and Cleaning

To avoid electrical shock or damage to the multimeter, do not get
water inside the case. Remove the test leads and any input signals
before opening the case.

Cleaning the multimeter:

• Wipe the case with a soft damp (not wet) cloth and mild detergent.

• DO NOT use abrasives or solvents.

• Dirt or moisture in the terminals can affect readings.

Cleaning the terminals:

• Turn the meter off and remove all test leads.

• Shake out any dirt that may have gathered in the terminals.

• Soak a clean swab or cotton bud with a cleaning and oiling agent (such as WD-40).

• Work the swab/bud around in each terminal until you are happy there
are clean. The oiling agent insulates the terminals from moisture-related
contamination.

Before replacing the battery and fuses, disconnect test leads from
any circuit under test, turn the multimeter 'OFF' and remove test
leads from the input terminals.
To prevent damage to the meter or personal injury, always replace
the battery or fuse with specified rating.

6.2 Battery replacement

When the battery voltage drops below a usable operation range the symbol
will appear on the LCD display, this indicates that the battery will need replacing.
To do this follow these steps.

1. Set the meter to 'OFF' state.

2. Disconnect test leads from any input terminals.

3. Use the appropriate screwdriver to unscrew the secured back cover. This will
expose the batteries.

4. Replace the battery with a new 9V battery (1604).

5. Replace the battery cover and screw securely back into place.

6. The multimeter should now be fully functional.

6.3 Fuse replacement

1. Set the meter to 'OFF' state.

2. Disconnect test leads from any input terminals.

3. Use the appropriate screwdriver to unscrew the secured back cover and then
the battery cover.

4. Replace the fuse only with an F 200mA/250V fuse.

5. Replace the 2 back covers and screw securely back into place.

6. The multimeter should now be fully functional.
