4. Instruccions de funcionament
The PeakTech 3385 offers 20 different measurement ranges. Always select a range higher than the expected value to prevent damage to the meter.
4.1 Mesurar DC Voltage (DCV)
- Introduïu el cable de prova negre al COM presa i el cable de prova vermell al VΩmA jack.
- Set the function switch to the desired DCV range (e.g., 15V, 60V, 150V, 600V). Start with the highest range if the voltage es desconeguda.
- Connecteu els cables de prova al component o circuit que s'ha de mesurar.
- Llegeix el voltage value from the appropriate DCV scale on the analog display.
4.2 Mesurar AC Voltage (ACV)
- Introduïu el cable de prova negre al COM presa i el cable de prova vermell al VΩmA jack.
- Set the function switch to the desired ACV range (e.g., 15V, 60V, 150V, 600V). Start with the highest range if the voltage es desconeguda.
- Connecteu els cables de prova al component o circuit que s'ha de mesurar.
- Llegeix el voltage value from the appropriate ACV scale on the analog display.
4.3 Measuring DC Current (DCA)
Precaució: Always connect the meter in series with the circuit. Never connect it in parallel across a voltage source when measuring current.
- Introduïu el cable de prova negre al COM jack.
- For currents up to 500mA, insert the red test lead into the VΩmA jack. For currents up to 10A, insert the red test lead into the 10A jack.
- Set the function switch to the desired DCA range (e.g., 100µA, 10mA, 500mA, 10A).
- Obriu el circuit on es vol mesurar el corrent i connecteu el mesurador en sèrie.
- Read the current value from the appropriate DCA scale.
4.4 Mesura de la resistència (Ω)
Precaució: Assegureu-vos que el circuit estigui desenergitzat i que tots els condensadors estiguin descarregats abans de mesurar la resistència.
- Introduïu el cable de prova negre al COM presa i el cable de prova vermell al VΩmA jack.
- Set the function switch to the desired Ω range (e.g., x1, x10, x100, x1k).
- Short the test leads together. Adjust the Ω ADJ knob until the needle points exactly to zero on the resistance scale.
- Connecteu els cables de prova al component que s'ha de mesurar.
- Read the resistance value from the Ω scale and multiply by the range factor.
4.5 Prova de continuïtat
The continuity test provides an audible indication for low resistance circuits.
- Introduïu el cable de prova negre al COM presa i el cable de prova vermell al VΩmA jack.
- Set the function switch to the continuity symbol (often indicated by a speaker icon).
- Connect the test leads across the circuit or component. If continuity exists (low resistance), the meter will emit an audible tone.

5. Manteniment
5.1 Neteja
Per netejar el mesurador, netegeu la carcassa amb aiguaamp drap i un detergent suau. No utilitzeu abrasius ni dissolvents. Assegureu-vos que el mesurador estigui completament sec abans d'utilitzar-lo.
5.2 Substitució de la bateria
When the meter's display indicates a low battery, or if resistance/continuity functions become unreliable, replace the batteries as described in Section 3.2.
5.3 Canvi de fusibles
The PeakTech 3385 is equipped with internal fuses to protect against overcurrent. If the current measurement function stops working, the fuse may need replacement. This procedure should only be performed by qualified personnel.
- Ensure the meter is turned off and all test leads are disconnected.
- Obriu la tapa del compartiment de la bateria a la part posterior del mesurador.
- Carefully remove the old fuse(s). Note the ratings: one for 500mA MAX and another for 10A MAX.
- Replace with fuses of the exact same type and rating. Using incorrect fuses can compromise safety and damage the meter.
- Tanqueu la tapa del compartiment de la bateria i assegureu-la.
