The communication function of CA71 Communication Software enables users to set output values of the CA71 on a PC. However, the range for generation/measurement should be selected using the rotary switch on the calibrator.
The following operations can be executed while monitoring the CA71 on the PC.
Data Receiving | Memory-mode data or real-time data can be received from the CA71. |
---|---|
Data Transmission | Setting value of generation can be set and sent to the CA71. |
Data Processing | The data can be saved and forwarded to EXCEL. A trend graph is created and shown on the PC screen. |
