Informació de seguretat
Always adhere to safety precautions when using the multimeter to prevent electric shock or damage to the instrument. Read all instructions before use.
- No supereu els valors d'entrada màxims per a cap interval.
- Tingueu precaució quan treballeu amb voltagper sobre de 30 V CA RMS, 42 V pic o 60 V CC. Aquests voltagsuposen un risc de xoc.
- Before measuring current, ensure the circuit is de-energized and the multimeter is connected in series.
- Always disconnect test leads from the circuit before changing functions.
- Inspect test leads for damaged insulation or exposed metal before each use.
- No feu servir el multímetre si sembla que està danyat o si la carcassa està oberta.

Connexió dels cables de prova:
Always connect the black test lead to the COM jack. Connect the red test lead to the appropriate input jack based on the measurement type.
- Per al voltage, Resistance, Frequency, Capacitance, and Temperature measurements, connect the red lead to the VΩHzTemp jack.
- Per mil·liampere o microampere current measurements, connect the red lead to the mAµA jack.
- Per ampere current measurements, connect the red lead to the A jack.
Instruccions de funcionament
Funcionament general:
- Turn the rotary switch to the desired measurement function.
- Connecteu els cables de prova al circuit o component que s'està provant.
- Llegiu el valor de mesura a la pantalla LCD.
- Utilitza el GAMMA button to switch between auto-ranging and manual ranging if needed.
- Premeu el botó MANTENIM button to freeze the display reading. Press again to release.
Specific Measurement Modes:
Mesura de la resistència:
Turn the rotary switch to Ω. Ensure the circuit is de-energized before measuring resistance. Connect the test leads across the component. The display will show the resistance in Ohms (Ω), kilo-ohms (kΩ), or mega-ohms (MΩ).
Current Measurement (DC/AC):
Turn the rotary switch to A~ (AC Current) or A- (DC Current). Important: Disconnect power to the circuit. Connect the multimeter in series with the circuit. Reapply power. The display will show the current reading. Be mindful of the maximum current rating for each input jack (mAµA vs. A).
Mesura de la capacitat:
Turn the rotary switch to the capacitance symbol (typically a capacitor icon). Ensure the capacitor is fully discharged before connecting the test leads. Connect the leads across the capacitor. The display will show the capacitance in Farads (F), microfarads (µF), or nanofarads (nF).
Mesura de la temperatura:
Turn the rotary switch to Temp. Connect the temperature probe (thermocouple) to the VΩHzTemp and COM jacks, observing polarity. Place the probe tip on or near the object whose temperature is to be measured. The display will show the temperature in Celsius (°C) or Fahrenheit (°F).
Manteniment
Neteja:
Netegeu el cas amb l'anunciamp drap i detergent suau. No utilitzeu abrasius ni dissolvents. Mantingueu els terminals d'entrada lliures de brutícia i humitat.
Substitució de la bateria:
When the battery indicator appears on the display, replace the batteries as described in the "Battery Installation" section under Setup. Prompt battery replacement ensures accurate readings and proper operation.
Substitució de fusibles:
If the current measurement function fails, the fuse may need replacement. Refer to the specifications for the correct fuse type and rating. Fuse replacement should only be performed by qualified personnel. Ensure the multimeter is disconnected from all circuits and turned off before opening the case.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Sense pantalla o pantalla tènue | Piles gastades o baixes | Substituïu les piles. |
