HY-LCT/LCTA Test instrument is a universal portable test device,mainly for various types of analog load cells,digital load cells,analog weighing indicators, big screen display and on-site troubleshooting for some interfaces.

Main features:

1.Test the capacity ,sensitivity and output signal of analog sensor (in

microvolt).And conversion to display the current actual weight, used to

judge the performance of analog sensor;

For example, zero output, stability,linearity and others parameters.More

accurate, more intuitive, eliminated the traditional by multimeter to

measure the input and output resistance method;

2.Check the digital sensors AD code,and conversion display the current

actual weight,used to judge the relative performance of digital sensors,

such as the over output,stability,linearity and others parameters;

3.It can automatically read or set the digital sensor address,zero setting and

calibration operation for full capacity.(calibration function for VIP users);

4.Decimal point can be set and display the division value and filtering parameters, used as a conventional analog instrumentation;

5.It can output 0-20mv analog signal,1/4000 precision.For detecting or calibration traditional analog indicators.

6.Through RS232 to test the big screen display is normal or patible with a variety of the communication protocol of big screen display from different manufactures(Yaohua and Qiuhao) and continuous improvement.

7.Test the computer serial port is damaged or not.
