Need help?Do you have a question about the Silva Map Measurer Plus and is the answer not in the manual?
The SILVA Map Measurer Plus (Art.no. 55068) is a precise device designed for map measuring and trip planning, suitable for use with virtually any map on both land and sea. It measures travel distance in kilometers, miles, and nautical miles, calculates estimated travel time, and features a countdown timer that displays the remaining time to your destination.
The device features an LCD display, a measuring wheel, a Measure button, an LCD backlight button, an ADJUST button, a MODE button, a battery compartment, an attachment clip, and a reference arrow. An LCD sticker is placed on the LCD glass when purchased and should be removed before use.
To install or replace the battery, unscrew the attachment clip from the body using a screwdriver. Open the battery compartment cover by turning it counterclockwise with a coin. Insert a new CR2032 battery with the positive (+) side facing up. Ensure the O-ring is correctly positioned, then close the battery compartment cover by turning it clockwise.
To set the time, press and hold the ADJUST button for 2 seconds. The hour digit will start flashing. Turn the measuring wheel clockwise to increase the value or counterclockwise to decrease it. Press ADJUST to confirm and switch to minute setting. Turn the measuring wheel to set the minutes. Press ADJUST to confirm and switch to seconds setting. Turn the measuring wheel to reset seconds to zero. Press the ADJUST key to confirm the setting. Continue the process to set the 12/24-hour format, month, date, and year.
Setting the correct map scale is crucial for accurate distance measurement. Press the MODE button repeatedly until "SCALE" is displayed. Press and hold ADJUST for 2 seconds. The display will show "1: 00050000" (1:50 000 is the default scale). The first zero will start flashing. Turn the measuring wheel clockwise to increase the value or counterclockwise to decrease it. Press ADJUST to confirm and switch to the next digit. Adjust each digit similarly or exit the setting by pressing and holding ADJUST for 2 seconds.
The speed setting enables the "time to go" function to calculate the estimated travel time, which is useful for trip planning. Press the MODE button repeatedly until "SPEED" is displayed. Press ADJUST repeatedly to set the speed unit (km/h, mph, knots). Press and hold ADJUST for 2 seconds. The display will show "005.0 km/h" (5.0 km/h, 3.1 mph, or 2.7 knots, depending on the selected unit, is the default speed). The first zero will start flashing. Turn the measuring wheel clockwise to increase the value or counterclockwise to decrease it. Press ADJUST to confirm and switch to the next digit. Adjust each digit similarly or exit the setting by pressing and holding ADJUST for 2 seconds.
Once the unit is set up, it is ready for use. The MODE button cycles through the following sequence: Time > Alarm > Distance > Time to go > Scale > Speed.
Press the MODE button repeatedly until "DISTANCE" is displayed. Press ADJUST repeatedly to set the measuring unit (km, mile, nautical mile). This can be done at any time during measurement. Press the MEASURE button to activate the measuring function; the "DIST" icon will start flashing. Place the measuring wheel at the desired location on the map and begin measuring by rolling the wheel along the desired route. Ensure the reference arrow points to the start and stop of the route for accurate measurement.
For best accuracy, drag the map measurer at a slow and steady pace (not faster than 5 cm/sec or 2 inch/sec), holding it like a pen with the palm of your hand supporting the surface. The direction of measurement does not affect the distance. You can deduct distance by rolling back along an incorrect part of the route and then continuing measurement, which is useful for correcting a measured route. Press the MEASURE button again to deactivate the measuring function, which locks the value and prevents accidental adjustments. Press MEASURE again to resume measurement. To reset the measurement, press and hold ADJUST for 2 seconds. Note: To access any other mode, the map measuring function must be deactivated.
After measuring the distance, the "time to go" function will display the required travel time to your destination. Press the MODE button repeatedly until "TIME - TO - GO" is displayed. The calculated time (based on the set speed) will be shown. Press ADJUST to start the timer and begin travel. Press ADJUST to pause the timer and press ADJUST again to resume. To reset the countdown timer to the initial time, press and hold ADJUST for 2 seconds. To delete the time, press and hold ADJUST for 2 more seconds. This action will also delete the measured distance.
The time function operates as a normal clock. Press ADJUST to display the date.
Press the MODE button repeatedly until "ALARM" is displayed. Press and hold ADJUST for 2 seconds to set the alarm. The hour digit will start flashing. Turn the measuring wheel clockwise to increase the value or counterclockwise to decrease it. Press ADJUST to confirm and switch to minute setting. Turn the measuring wheel to set the minutes. Press ADJUST to confirm. An alarm icon will indicate when the alarm is activated. Press ADJUST in alarm mode to turn the alarm ON/OFF.
Never attempt to disassemble or service the unit. Protect the electronic module from extreme heat, shocks, and prolonged exposure to direct sunlight. The unit can be wiped clean with a lightly moistened cloth and mild soap. Do not expose the unit to strong chemicals such as gasoline, clean solvents, acetone, alcohol, or insect repellents, as these may damage the unit's seal, case, and finish. Store the unit in a dry place when not in use. Avoid direct contact with hair liquids, colognes, sunblock creams, and other toiletries, which can cause deterioration of the plastic parts. If the unit comes into contact with these substances, wipe it off immediately with a dry, soft cloth.
