Digital multimeter
C-LOGIC 520
Code: 301000043
ENGLISH
The meter is a small, safe and reliable 3 1/2 digit handheld multimeter. This meter can
measure AC/DC voltage, DC current, resistance, diode, continuity and battery test. This tool
is ideal for professionals and hobbyists alike.
INFORMACIÓN DE SEGURIDAD
The meter meets the safety standards UL61010-1, CSA C22.2 No. 61010-1, CAT II 600V
and a pollution degree 2.
• The protection provided by the meter can only be ensured if all safety procedures are
strictly followed.
• The safety symbols on the meter are to advise of potential dangerous situations. Caution is
required when measuring close to the meter´s safety limits.
• Never exceed the protection limit values indicated in the specifications for each range of
measurement.
Warning
The special attention should be paid when using the meter because the improper usage
may cause electric shock and damage the meter. The safety measures in common
safety regulations and operating instruction should be complied with when using. In order
to make fully use of its functions and ensure safe operations please comply with the
usage in this section carefully. If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
PRECAUTIONS
• To avoid electrical shock or personal injury, observe and follow all safety precautions.
• Check the meter for damage before use. Do not use if any damage is observed.
• Check the test leads for cracks or exposed wires before using the meter. Replace if
necessary.
• Ensure the meter works properly by testing a known voltage source first. If not working
properly, the protective equipment may be damaged; have the meter serviced before using.
• Never measure voltages that may exceed the protection limit indicated on the meter.
• Always be careful when working with voltages above 60V dc or 30V ac rms. Keep fingers
behind the probe barriers when making voltage measurements.
• Make sure the test leads are in the correct input jacks before measurement.
• Do not expose the meter to explosive gas, dust or vapor.
• When connecting the test leads to a measurement circuit, connect the common lead first,
then the live lead. Reverse when disconnecting.
• Turn off power to circuit and discharge all capacitors before making resistance, continuity
or diode measurements.
• In order to avoid incorrect DC voltage readings, check the circuit for AC voltage first, then
put the meter in the appropriate DC voltage range.
• Turn off circuit power and check fused before connect the leads when measuring current.
Turn circuit power on after making connection.
• Never use the meter unless the back cover is in place and fastened securely.
• When the low battery indicator
meter cannot be guaranteed while the low battery indicator is on.
• Before opening the case, always disconnect test leads from all energized circuits.
• For continued protection against fire, replace fuse only with the specified voltage and
current ratings listed in the manual.
MAINTENANCE
This section provides basic information on maintaining the meter, such as replacing fuses
and the battery. Only experienced and authorized personnel should make repairs to the
meter.
Warning
Para evitar lesiones o daños en el multímetro, no permita la entrada de humedad dentro
del equipo y retire los cables de prueba antes de abrir la tapa de la pila.
• Use a damp cloth to regularly clean the outside of the meter. Do not use abrasives or
chemical solvents. Dirty or damp input jack can adversely affect readings.
• To clean input jacks, follow the following steps:
1. Turn off the instrument and remove the test leads.
2. Clear any dirt or other particles on the input jacks.
3. Use a cotton ball/swab with a lubricant to clean off the contacts of the input jacks.
4. Use a separate cotton ball/swab for each jack to prevent cross-contamination.
REPLACING THE BATTERY AND FUSES
• Under normal conditions, it is unnecessary to replace the fuse. Don´t replace it until the
probes are unplugged and the power is shut down. Take out the two screws of the rear
cover to remove the housing.
• The specification of the fuse is: F1: F 10A H 250V, F2: F 250mA H 250V. The replacement
should be of the same specification.
• The battery for this multimeter is 9V NEDA 1604 or 6F22. The replacement should be of
is displayed, replace the battery. The accuracy of the
the same specification.
• Don´t put the instrument into use until the rear cover is screwed after replacing battery or
fuse.
Warning
To avoid electric shock, make sure the probes are disconnected from the measured circuit
before removing the rear cover. Make sure the rear cover is tightly screwed before using
the instrument.
REPLACING THE PROBE
If insulation on probe is damaged, replace it.
Warning
Use meet EN 61010-031 standard, rated CAT II 600V, 10A or better probe.
