1 Introduction The MULTI 3100 measures and displays speed, water depth and water temperature. It can calculate and display average speed, maximum speed, trim speed, trip log (distance) and total log. An installed MULTI 3100 usually has two parts: 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. The display unit.
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. To change the value displayed in the bottom part of the screen, press one or more times to select: Speed. Depth. Trip log (distance). Total log (distance). Battery voltage. Countdown timer.

3 Speed, average speed, maximum speed, trim speed The unit can display several speeds: A higher value averages readings over a longer period of time. This gives the most stable speed but will ignore some true speed changes. 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.
Calibrate by speed In this method, travel at a measured, constant speed. Use the speed displayed on a GPS receiver, follow another boat travelling at a known speed or make a timed run over a known distance. Note that for accurate calibration: The speed from a GPS receiver should be above 5 knots. The speed from another paddlewheel transducer e.g. another boat - should be between 5 and 20 knots. Best results are achieved in calm conditions where there is minimal tidal current (best at high or low tide).
5 Depth, keel offset, too deep alarm, too shallow alarm Depth and keel offset The displayed depth is the distance from the transducer on the boat to the bottom of the water, plus or minus an offset which is called the keel offset: will display the depth from the surface to the bottom of the water. A negative keel offset displays depth as measured from a point below the transducer. A positive keel offset displays depth as measured from a point above the transducer.
6 Temperature Temperature is measured by a sensor in the speed transducer. Water temperature 6-1 Set temperature units The units can be either °C or °F: Press until the temperature is displayed, then hold until the units change. 6-2 Calibrate temperature The unit is factory calibrated and should not normally need calibrating. To calibrate: 1 Measure the water temperature near the speed transducer.
8 Systems of several instruments Several NAVMAN instruments can be connected together during installation to share data. There are two ways of connecting instruments together, NavBus or NMEA. 8-2 NavBus 8-1 NMEA When instruments are connected by NavBus: NMEA is an industry standard. Speed, depth, temperature and log data may be output which can be read and displayed by any compatible NAVMAN (eg REPEAT 3100) or other NMEA instrument.
9-3 Transducers The MULTI 3100 is usually used with a through hull depth transducer and a separate through hull speed/ temperature transducer. However, the unit can take readings from another instrument, in which case it may not need transducers (see section 8). Through hull transducers generally give the best performance and are the best choice for displacement hulls. They are mounted in a hole drilled through the bottom of the boat. Plastic through hull transducers are suitable for GRP or metal hulls.
Away from engines, fluorescent lights, power inverters and radio or radar transmitters. Accessable from behind; the minimum clearance required at the back is 50 mm (2") (see mounting diagram). With the back of the unit protected from moisture. 2 The unit must mount on a flat panel which is less than 20 mm (0.75") thick. Stick the mounting template in place. Drill a 50 mm (2") fixing hole through the centre hole in the template. Note that the template allows space around the unit for the protective cover.
external speed input from an instrument with a speed transducer (see section 8-1): i Press + several times until the Speed Mode screen is displayed: ii Press or to change the mode to GPS (when using a speed transducer, the mode should be SEn). iii Press 3 If the unit is part of a system of 3100 series instruments connected by NavBus, set the unit’s backlight group number (see section 8): i Press + several times until the Backlight Group screen is displayed: ii Press or number. iii Press 4 .

Appendix B - Troubleshooting This troubleshooting guide assumes that you have read and understood this manual. 3 It is possible in many cases to solve difficulties without having to send the unit back to the manufacturer for repair. Please follow this troubleshooting section before contacting the nearest NAVMAN dealer. There are no user serviceable parts. Specialized methods and testing equipment are required to ensure that the unit is reassembled correctly and is waterproof.
