It can calculate and display average speed, maximum speed, trim speed, trip log (distance) and total log. An installed NS3100 Multi usually has two parts: The display unit. Depth and speed / temperature transducers which are attached to the hull and wired to the display unit. The unit is powered from the boat's power supply. The NS3100 Multi is part of the Northstar family of instruments for boats, which includes instruments for speed, depth, wind and repeaters. These instruments can be connected together to form an integrated data system for a boat (see section 8). For maximum benefit, please read this manual carefully before installation and use. How the transducer measures depth The depth transducer generates an ultrasonic (sound) pulse, which travels down through the water. When the pulse meets the bottom, some of the pulse is reflected back up towards the boat and is received by the transducer. The NS3100 Multi display unit The display unit analyses the reflections from each pulse. It removes unwanted reflections (from bubbles and other objects) and calculates the depth by measuring the time between sending the pulse and receiving its echo. How the transducer measures speed The speed transducer has a small paddlewheel which spins as the boat moves through the water. The transducer measures how fast the paddlewheel is spinning and calculates the boat speed by averaging several measurements. Cleaning and maintenance Clean the display unit and any plastic transducers with a damp cloth or mild detergent. Avoid abrasive cleaners, petrol or other solvents. When repainting the hull, cover or remove any visible transducers. Depth transducers may be coated with a thin layer of antifouling paint; gently sand off any previous paint first. 4 Northstar NS3100 MULTI 2 Operation 2-1 Turn on and off Turn the unit on and off with the auxiliary power switch on the boat. The unit does not have its own power switch. When you turn it off, any settings you have made are retained. If the word SIM flashes at the bottom, right of the display, then the unit is in simulate mode (see section 2-5). 2-2 Basic operation The keys The unit has four keys, labelled and . In this manual: Press means to push the key for less than one second. Hold for two seconds means to hold the key down for two seconds or more. Press one key + another key means to push both keys together. Change the items displayed The display can show two values at once, one in the top part of the screen and one in the bottom. If an item displays as dashes (-- --) then it means that the value is outside the range, for example the depth might be too deep or unknown. To change what is displayed in the top part of the one or more times to select: screen, press Speed. Avg speed. Max speed. Trim speed. Depth. Temperature. To change the value displayed in the bottom part of one or more times to select: the screen, press Speed. Depth. Trip log (distance). Total log (distance). Battery voltage. Countdown timer. Set backlight level for screen and keys You can set the backlight to one of four brightness levels or off. Press once to display the current backlight level, press again to change the level: Backlight Level 2 Reference Manual and Installation Manual 5 2-3 Change units To change the speed and log units, press until Speed is displayed, then hold until the units change; if necessary, hold again until the units change again. To change the depth units, press until DEPth is displayed, then hold until the units change; if necessary, hold until the units change again. To change the temperature units, press the temperature is displayed, then hold the units change. until until 2-4 Alarms The NS3100 Multi can be set to sound an alarm when the water is too deep or too shallow (see sections 5-2 and 5-3). When the alarm sounds, the internal beeper sounds, the symbol on the display flashes and any external beepers or lights operate. Press to mute the alarm. The alarm stays muted until the depth becomes returns to the pre-alarm condition or is within the alarm parameters. The alarm will sound if the depth becomes too deep or too shallow again. 2-5 Simulate mode Simulate mode allows you to become familiar with the unit off the water. In Simulate mode, the NS3100 Multi functions normally except that the transducers are ignored and the unit generates this data internally. The word SIMULATE flashes at the bottom, right corner of the screen. To turn Simulate mode on or off: 1 Turn the power off. 2 Hold down while you turn the power on. 6 Northstar NS3100 MULTI 2-6 Key reference Turn power on Set alarms Hold Hold + 5 sec Turn Simulate on or off Reset memory Set Too Deep alarm Hold 2 sec Set Too Shallow alarm Hold 2 sec Turn alarm on or off Increase alarm depth Decrease alarm depth Return to normal operation Normal operation Hold + Change top display (Speed, Avg speed, Max speed, Trim speed, Depth, Temperature) Change bottom display (Speed, Depth, Log, Total log, Battery voltage, Countdown timer) Mute an alarm Adjust backlight (4 levels or off) Reset top value to zero (Avg speed, Max speed, Trim speed) Reset bottom value to zero (Log, Total log (hold for 5 sec) Start or stop countdown timer) Change units of top value (e.g. knots, metres, °C) Change units of bottom value (e.g. knots, metres) 2 sec Setup Set Speed Damping + Set Countdown Timer Start Time + Set Keel Offset + Set Temperature Calibration + Mode is SEn + Set Speed Mode Sen(sor) or GPS Set Speed Calibration + Set Log Calibration Mode is GPS + Set Speed Resolution + Set Backlight Group + Increase value or change setting Decrease value or change setting Return to normal operation + + Hold 2 sec Hold 2 sec Reference Manual and Installation Manual 7 3 Speed, average speed, maximum speed, trim speed The unit can display several speeds: Speed: The current boat speed. Avg speed: The average speed since Avg speed was reset or the unit was switched on. Max speed: The maximum speed since Max speed was reset or the unit was switched on. Trim speed: Trim speed may be used for tuning racing boats. Trim speed measures changes in boat speed, relative to when you reset trim speed to zero. For example, if the boat is trave ...
