Details:
VICTOR 8245 is a USB computer interface, memory, clock display, square-wave output, vacuum screen, automatic range conversion for 4 1/2 digit keys table, is a stable, AC220V power supply drive high-reliability digital form. Table 140*40mmVFD displays, reading is clear; Data retention, maximum/minimum value, relative value measurement function.
This table can be used to measure DC and AC voltage, DC and AC current, resistance, capacitance, temperature, diode continuity buzzer, square-wave output, parameters such as frequency and duty cycle. Machine with dual slope a/d conversion LSI as the core, with automatic and manual selection function, is a superior tool table are laboratories, factories, radio amateurs and ideal for families.
