Automatic Bench Type Digital Multimeter polarity test With Clock Display
VICTOR 8245 22000 (4 1/2) digit automatic polarity Bench Top Digital Multimeter TRUE RMS Multimeter with RS232
I. General
It is a 4 1/2-bit digital key bench meter with USB computer interface, storage, clock display, square wave output, vacuum phosphor screen and automatic range change, and a high-reliability digital bench meter with stable performance and driven by AC220V power supply. It adopts 140*40mmVFD display of clear readings and has the functions of data retention, max./min. and relative value measurement.
This meter can be used to measure such parameters as DCV, ACV, DC, AC, resistance, capacity, temperature, diode, continuity, square wave output, frequency, duty ratio, etc. Centered on the dual slope A/D conversion of large-scale integrated circuit, the whole set has the function of automatic and manual selections and thus is a meter with excellent performance and a desirable tool for labs, factories, radio fans and homes.
