3.Uncertainty: 50 ppm
4.Adjustment Fineness: 5nΩ
5.2-wire or 4-wire Resistance Mode
6.There is no residual resistance of the transfer switch and contact resistance.
7.LCD Touch Screen

3. Application

1. Calibration of Class 0.02 and below single and double arm bridges (e.g. QJ44, QJ42, QJ57)
2. Calibration of Class 0.02 and below DC resistance meter
3. Calibration of Class 0.02 and below temperature measuring bridge

 

4. Characteristics
 

☆ Multiple output methods

The instrument has a "fixed point output" mode, through the digital button of the operation table or click the touch screen, directly set the required output value, the instrument will automatically switch to the best range output.

☆ Multiple output methods

 

 

When calibrating a resistance tester, it is usually necessary to select the calibration point according to the proportion of each range of the meter to be checked.

The user can easily select the calibration point of the inspected meter through the "Percentage Output Button" on the console of this instrument or the "Percentage Check Point" on the touch screen.

The operating area is equipped with a "rotary encoder" that increases or decreases the output by rotating it clockwise or counterclockwise.

 

Statistical analysis of test data
S/N	Function
1	Integration period: The integration period can be set in the range of 0.5 s ~ 20 s (default 1 s), which is convenient for users to set sampling data according to actual needs;
2	Statistical analysis: real-time recording and statistical test data, including current average Avg, mean square deviation S.dev, peak-to-peak P-P, and maximum value Max, minimum min, test number N, time time, etc., easy for users to read intuitively;

☆ Rich communication interface and special test software

RS232, USB, LAN interfaces.
