5. Configuració

5.1. Instal·lació de la bateria

The Fluke 175 multimeter operates on one 9-Volt battery (included). The meter features an easy-access battery door, allowing for battery changes without breaking the calibration seal.

1. Assegureu-vos que el multímetre estigui APAGAT.
2. Localitzeu el compartiment de la bateria a la part posterior del mesurador.
3. Open the battery door using a screwdriver if necessary.
4. Insert the 9-Volt battery, observing correct polarity.
5. Tanqueu la porta de la bateria de manera segura.

5.2. Connexió dels cables de prova

Proper connection of test leads is crucial for accurate and safe measurements.

1. Introduïu el cable de prova negre al COM presa d'entrada (comuna).
2. Per a la majoria de volumstage, resistance, continuity, capacitance, and diode measurements, insert the red test lead into the VΩHz presa d'entrada.
3. For current measurements, insert the red test lead into the mA or 10A input jack, depending on the expected current level. Refer to the specific measurement section for details.

6. Instruccions de funcionament

Before taking any measurement, ensure the meter is set to the correct function and range, and the test leads are connected properly.
