Use HI 920010 (9 to9-pin) connection cable.The meter must be in measurement mode to communicate.The meter port is optoisolated and transmits data with a Baud rate of2400 bps.The user can retrieve the GLP data, request meterís parameters and thecurrent reading (current range only) from the PC directly. It is also possible tosend a command from the PC to change ranges.To communicate with the PC use the optional HI 92000 communicationsoftware. The software is provided with an exclusive on-line guide of all thecommands available and allows data printing, plotting and exporting.CHI2300Microprocessor Conductivity MeterALT FunctionsFunctionsTCATCALTLOCKSETUPGLPRANGECFMCALCALTDisplay TC FactorTCView CalibrationDataGLPSETUP Enter Setup ModeStart TemperatureCalibrationCALTTemperatureCompensationATCConfirm ValueCFMChange Value/Lock Current RangeLOCKStart CalibrationCALSelect MeasurementRangeRANGE
