4. Configuració

4.1 Instal·lació de la bateria

The HABOTEST HT121 is powered by two 1.5V AAA batteries. To install or replace batteries:

1. Assegureu-vos que el multímetre estigui apagat.
2. Localitzeu la tapa del compartiment de la bateria a la part posterior del dispositiu.
3. Utilitzeu un tornavís per obrir el compartiment de la bateria.
4. Insert two AAA batteries, observing the correct polarity (+/-).
5. Tanqueu de manera segura la tapa del compartiment de la bateria.

The meter features a low battery indication. Replace batteries promptly when this indicator appears to maintain measurement accuracy.

5. Instruccions de funcionament

5.1 Encès/Apagat

Premeu el botó Poder button to turn the multimeter on. Press and hold the Poder button again to turn it off. The device also features a 15-minute auto power-off function to conserve battery life.

5.2 Smart Function (Auto Recognition)

In Smart mode, the multimeter automatically identifies the measurement signal for DC/AC voltage, resistance, and continuity. This simplifies operation by eliminating the need for manual range selection.

5.3 Mesures específiques

For specific functions not covered by Smart mode, or to manually select a range, use the EMPLEAT botó.

• DC/AC Voltage: Connect the test lead to the COM port and the probe to the circuit. The meter will automatically detect AC or DC voltage in Smart mode. For manual selection, press FUNC until the desired mode is displayed.
• Resistència: Ensure the circuit is de-energized before measuring resistance. Connect the test lead and probe across the component.
• Capacitat: Discharge capacitors before testing. Connect the test lead and probe across the capacitor terminals.
• Freqüència: Connect the test lead and probe to the signal source.
• Continuïtat: Use to check for open or closed circuits. A low resistance reading (typically below 50Ω) indicates continuity, often accompanied by an audible beep.
• Prova de díode: Use to check the forward voltagcaiguda e d'un díode.
• Live Test: Detects live wires. When performing a LIVE induction test, the multimeter provides an intelligent sound and light reminder.

• NCV (vol sense contacte).tage) Detecció: Hold the NCV probe near a conductor to detect AC voltagi sense contacte directe.
• Three-Phase Sequence Detection: Used to determine the phase sequence in three-phase systems.

5.4 Data Hold and Flashlight

• Conservació de dades: Premeu breument Data Hold/Flashlight per congelar la lectura actual a la pantalla. Premeu-la de nou per alliberar-la.
• Llanterna: Premeu llargament el botó Data Hold/Flashlight button to turn the built-in LED flashlight on or off.
