1. Summary

TH1950 High Precision Multi-function Calibrator is a new generation of top-level multi-function calibrator with a wider calibration range and higher calibration accuracy. It can output AC and DC voltage and current signals with excellent performance and has built-in high-stability standard resistors. It can calibrate various series of digital multimeters and other precision electrical measuring instruments, and is widely used in power grids, measurement and testing, industrial manufacturing, scientific research and other fields.

2. Features of TH1950 High Precision Multi-function Calibrator

• High-precision multi-function signal output

• Calibrate 7.5 and 8.5 digit multimeters

• Supports AC and DC current expansion output to 120A (with TA1000)

• Excellent output stability, DCV 24h short-term stability ≤ 1 ppm

• Suports various value output: touch screen output (5-inch screen), button output and rotary knob output

• Rich Calibration Functions: It can be used to calibrate digital multimeters, analog pointer meters, data loggers, chart recorders, panel meters and graphic multimeters, etc.

• Original Device Calibration Technology: By using measurement standards: TH0100 Advanced DC Voltage Reference Standard and TH0320 Reference Resistance Standard, all functions and ranges can be fully calibrated, greatly saving testing time and periodic calibration costs.

• Safety Protection Circuit: It has safety circuit protection functions, including voltage short circuit protection, current open circuit protection, overheating and overload protection, etc. The specially designed overcurrent fuse can also be easily replaced.

• Excellent Interaction Performance: High-definition large-size color touch screen, which can display multiple sets of parameters and information at the same time, and the selected capacitive touch screen makes operation sensitive and convenient, equipped with physical operation buttons and a rotary encoder, the calculator-style keyboard makes inputting values easier and faster.
