KWS1802C USB-tester stroommeter USB-C met digitaal display

El KWS1802C permet mesurar voltatge (4-30 V), corrent (0-5.1 A), potència instantània (0-155 W), capacitat acumulada (0-99999 mAh), temps (0-99 h) i temperatura interna (0-80 °C). És molt útil per monitorar la càrrega de dispositius USB-C, identificar consums anòmals i comparar carregadors i cables, especialment en entorns tècnics o per a anàlisi de rendiment en electrònica de consum.

Operar a prop del límit de 5.1 A o 30 V pot incrementar l’escalfament intern i la deriva del sensor. Per a la màxima fiabilitat es recomana utilitzar-lo amb marge respecte als valors màxims, idealment un 80% del rang. No és apte per a corrents o voltatges superiors; sobrepassar-los pot danyar l’equip i els dispositius connectats.

El KWS1802C ve calibrat de fàbrica i no disposa d’opció de recalibratge ni d’accés a firmware per part de l’usuari. No requereix manteniment regular més enllà d’evitar humitat i cops; es recomana guardar-lo en un lloc sec. Si arriba a mostrar lectures erràtiques, acostuma a ser símptoma de dany físic o fallada interna.

The KWS1802C can measure voltage (4-30 V), current (0-5.1 A), instantaneous power (0-155 W), accumulated capacity (0-99999 mAh), time (0-99 h) and internal temperature (0-80 °C). It is very useful for monitoring USB-C device charging, identifying abnormal power consumption, and comparing chargers and cables, especially in technical environments or for performance analysis in consumer electronics.

Operating close to the 5.1 A or 30 V limit can increase internal heating and sensor drift. For maximum reliability, it is recommended to use it with some margin below the maximum values, ideally at 80% of the range. It is not suitable for higher currents or voltages; exceeding them may damage the unit and the connected devices.

The KWS1802C comes factory calibrated and does not offer user recalibration or firmware access. It requires no regular maintenance beyond avoiding moisture and impacts; storing it in a dry place is recommended. If it starts showing erratic readings, this is usually a sign of physical damage or an internal fault.

KWS1802C kan mäta spänning (4-30 V), ström (0-5.1 A), momentan effekt (0-155 W), ackumulerad kapacitet (0-99999 mAh), tid (0-99 h) och intern temperatur (0-80 °C). Den är mycket användbar för att övervaka laddning av USB-C-enheter, identifiera onormal förbrukning och jämföra laddare och kablar, särskilt i tekniska miljöer eller för prestandaanalys inom konsumentelektronik.
