MSL600

7.11.1.9Xdr Tilt Time - D833

A diagnostic parameter indicating the time for which the transducer has been out of the water in min:secs.

7.11.1.10Noise Level - D834

A diagnostic parameter indicating the noise level in the tank as a % of full screen.

7.11.2 Diagnostics parameters D835 to D852

7.11.2.1Input Status - D835

A diagnostic parameter indicating the status of the digital input, 1 indicating active, 0 indicating not active.

7.11.2.2LE Count – D836

This gives an indication as to reliability of signal.

7.11.2.3Radio Channel - D842

This parameter is not used with this version of the MSL600.

7.11.2.4Radio Address - D843

This parameter is not used with this version of the MSL600.

7.11.2.5CU Temperature (Temperature of Control Unit) - D844

View this parameter to see the current temperature in °C (imperial – degrees F) inside the MSL600 control unit. This temperature is used for control of the LCD back light, turning it on to generate a degree of internal heating in cold weather and off when hot to avoid overheating.

7.11.2.6Xducer Temp (Temperature of Transducer) - D845

View this parameter to see the current temperature in °C (imperial - degrees F) of the transducer. This temperature is used in the compensation of the speed of sound in the supernatant.

7.11.2.7Free Memory (Logging Memory Free) - D846

View this parameter to see the amount of MSL600 logging memory remaining as a % before the end of the buffer is reached and over writing at the start begins. This parameter is compatible with Mobrey Measurement Log View software.

7.11.2.8Date of Change (Last date of Change) - D848

View this parameter to see the date of the last change to the configuration of the MSL600. This parameter can be used to detect unauthorised access.

7.11.2.9Echo Sharpness – D849

View this parameter to estimate the size of the echo. A typical reading would be between 20 and 30.
