Overview
TD1470 Single and Double Bridge Calibration Device ◉ TD1470 is an instrument that can accurately simulate a wide range of DC standard resistors from 100 μ Ω to 11 M Ω, with an optimal measurement uncertainty of 0.01%. The use of this instrument enables the overall calibration and verification of devices such as single and double arm bridges, digital bridges, digital micro ohmmeters, DC resistance meters, etc., with extremely convenient operation. Reference standards: JJG 125-2004 "Verification Regulations for DC Electric Bridges", JJG 837-2003 "Verification Regulations for DC Low Resistance Meters", etc.
Product Details
Features
◉ Fully digital adjustment and port programmable, with a low adjustment fineness of 5 n Ω, making it easy to detect the sensitivity of the tested meter, and having advantages that cannot be compared with physical resistance.
Compared with traditional physical standard resistance boxes, the adjustment fineness (typical value is 0.1 m Ω) is finer. And there is no residual resistance (typical value is m Ω level) or contact resistance of the conversion switch.
The maximum current measurement capability is up to 11 A, and it has full automatic range switching, strong resistance to current impact, and avoids physical resistance changes caused by current overload.
The instrument has undergone complete testing for electrostatic protection and electromagnetic compatibility, resulting in higher system reliability; It has self calibration function to ensure accurate and stable measurement values over time.
Equipped with a high-definition LCD touch screen, the measurement value display is more intuitive and the operation is more convenient.
