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.
3
5163440K_Instructions.qxd 18/09/2009 10:31 Page 4
• 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.

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 'D CV V or D Cm
2. Connect the black test lead to the C OM 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.
N OT
• 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.
E XT A N E::
• 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.

3. Connect the test leads to the circuit being measured and read the displayed value.
Tiip s ffo ea urriin g rre stta nc
• 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 60M
Ω range for in-circuit resistance measurements.
• On 60M
Ω 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.

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.
