CHAPTER 5: DIAGNOSTICS
The DL2 is a Doppler speed log system with 4-6 PCBs (depending on option choices), a signicant
amount of cabling, an acoustic sensor and a hull mounting. All of these elements can fail, and
SKIPPER has strived to make the system detect as many problems with these units as possible
automatically. If the system does show signs of measuring wrongly, do the following:
• Recycle the power (The DL2 has no power switch, use power input switches)
• Check the calibration
• Check the self diagnostics
The diagnostics will test the following parameters:
• NMEA outputs
• Communication to the sensor
• Sensor Receiver functionality
• Internal voltages
• Temperature
• Other internal parameters
If it nds an error, the diagnostic page will give you a suggestion of how to x the unit. If the error
is not found, Download and connect the SKIPPER service software (available on the SKIPPER
website www.skipper.no. Select the DL2 symbol and perform diagnostics from there. If this gives no
help, contact SKIPPER service or your local dealer. A full list of SKIPPER dealers is available on
www.skipper.no.
This page allows diagnostic testing, a speed simulation (forcing the sensor to simulate a speed. an
alert simulation and some parameters adjustments.
The diagnostics page is under continuous development and may change in software upgrades.
