Le multimetre V98A est un appareil de mesure de poche fonctionnant sur piles, pour mesurer de nombreux paramètres électriques. Il a toutes les qualités d'un multimètre numérique professionnel de grande précision pour les mesures suivantes :
Tension alternative (AC), tension continue (DC), courant alternatif (AC) , courant continu (DC), résistance, capacité, fréquence, rapport cyclique, dBm, température de thermocouple, température de sonde platine, test diode, et test de continuité.
Besides, it has features like:
❑
Large LCD screen could display the three characteristic of one input signals.
❑
Different reference impedance for dB measure function.
❑
AUTO HOLD, DISPLAY HOLD and PEAK HOLD to display the measuring value.
❑
Panel calibration function.
❑
Three convenient data recording modes: LOG mode, MANUAL mode, and
COMP mode.
❑
USB-IR jack to connect with a PC
