Analog Output (High) Meter Setup Setting range: 20.00 mS/cm to 0.02 µ S/cm The BI-650 meter contains an integrated setup menu for customizing (default 20.00 mS/cm) the displayed option to meet measurement requirement. The following table describes the functions of each menu item.
Temperature Compensation Conductivity Calibration The BI-650 meter is supplied with an industrial conductivity electrode. The BI-650 meter allows 1 to 3 points conductivity calibration. For better When the wires of electrode are connected to the meter, the display. accuracy, we recommend to perform 3 points calibration or select a will show ATC icon immediately.
Calibration and Measurement Communication The BI-650 meter uses a standard Modbus-RTU protocol. All of the data are character type (2 bytes). The response data ranges between -32767 to 32767, hexadecimal. PC Command Definition Length of Byte Data 1.6 Press the Enter key, the meter begins the calibration.
