Overview

Model TD1505, a high-precision DC standard, can accurately outputs DC voltage from 10 mV to 33 V, DC current from 10 μA to 22 mA with the accuracy of class 0.005.

Low noise, high precision, resolution and reliability。 Applied to be the power supply for DC resistance measurement bridge (e。g。 QJ19, QJ36, QJ44, QJ68, QJ64, etc。), to calibrate stress sensors and vibration sensors, and to calibrate DC voltmeters, ammeters and transmitters with a high accuracy。

Features

● Fast Adjustment Method: Fixed-point output, rotary encoder adjustment and programmed output.

● Protection: Open-circuit protection, overload protection and overheating protection.

● Display: Large LCD touch screen, more intuitive of value display and easier operation.

● Connection: Easy to build fully-automatic test system via RS-232 interface.
