The SB7300 multi-function standard source features high accuracy and stable, reliable performance. It can serve as a verification/calibration standard for general laboratories, and also be applied for on-site inspection and patrol testing.

Equipped with comprehensive powerful functions, the SB7300 can output excellent DC voltage & current, AC voltage & current, DC resistance, frequency, DC power and AC power with phase control. When matched with the optional 50-turn ampere-turn coil accessory, it can generate an equivalent ampere-turn current up to 1100 A for calibrating clamp meters and flexible current probes.

The SB7300 can directly calibrate analog multimeters, digital multimeters, clamp meters, voltage/current transmitters, secondary thermal instruments, voltage/current sensors of class 0.02 and below, as well as power meters and power analyzers of class 0.2 and below.
