  • Page 37: Log/Speed Calibration

    Pulses value can be altered by type of DPV, mounting position, and influence of for example “propeller suction” effect. Devices are calibrated to be used with Seacraft scooters, which construction allows for optimal sensor placement, and minimizes interferences. While for general orientation underwater factory setting will be fine with most types of DPV’s, for more precise applications- as for example mapping- we recommend speed log calibration with whole set-up used.
  • Page 38 The calibration procedure needs values in meters. No other units are available. 1 N.M. (Nautical Mile, U.S.) equals 852.0 meters. 100 feet equals 30.48 meters. 100 meters equals 328.08 feet. All above procedure is shown on the screens below: In order to calibrate the external log, first set the known and precisely determined test distance.
  • Page 39 On the end of the calibration distance press STOP (lower button again). The counter visible on the screen will show the number of pulses registered by the log. If this quantity is too low, the calibration will be canceled (the previous value will be kept).
  • Page 40 “f” can be calculates using following equation: ���� where: a = length of the section as measured with ENC3 b = current calibration factor (pulses / 100 m) c = precise known length of the route section For example: the section being measured has a length of exactly 127 m and ENC has indicated the route length of 124 m.

  • Page 42: Time/Date

    GPS information is refreshed automatically after each successful update on this screen. The GPS state is also reported as icon on the main screen. Green circle in the left-bottom corner of the screen will change his shape each time new GPS reading is received from the internal sensor.
  • Page 43 Caution: – The device may drop date & time settings, if the battery was deeply discharged. - The device clock accuracy is about 15 seconds per month. You may need to correct date & time settings from time to time. - Date and time are used in record files.

  • Page 44: Other Settings

    19. Other settings Miscellaneous other settings are available as a separate screen: The additional settings screen (MENU → SETUP → Other) is divided into 3 parts. The first part of the options shows the current settings: Backlight, Record every, Depth tresh. (...old), Auto-ON and Auto-OFF. The upper button goes through all these options one after the other, and then the next screen is displayed.
  • Page 45 Last part of settings screen Backlight – [1, 2, 3, 4, 5, auto] – Changes the display backlight intensity. Value 1 means the constant lowest brightness (about 20%), value 5 means the constant maximum brightness (about 95%), value ‘auto’ means that the backlight will be auto adjusted using the ambient light sensor.
  • Page 46 Automatic start of data recording will start if all of the following conditions are met simultaneously: - the ENC3 console is submerged to a depth at least equal to Depth tresh. (available on the first screen of additional settings) - Speed sensor detects water flow of at least 8 m / min for a minimum duration of 1.2 seconds. The flow must not be interrupted (no...
  • Page 47 The Auto-REC and Auto-HOLD options have lower priority than the REC and HOLD commands issued by the user. Thus, any REC / HOLD command activated by pressing a button on the ENC3 console will lock Auto-REC and Auto-HOLD for only 15 seconds. During these 15 seconds, the REC or HOLD state will remain as manually set by the user.
  • Page 48 The option is disabled by default. The ENC3 console has a built-in mechanism for writing markers. A marker is an additional “highlight” associated with a point on a recorded route. By default, each time you stop recording manually (with the button on the console), the device saves the current marker number in the memory and increases its number by a value of 1 until it reaches 99.
  • Page 49 ‘Disable GPS’ option The ENC3 console has a built-in GPS receiver that works continuously on the surface (when the calculated depth is 0.1 meters or less). The operation of the GPS receiver increases the consumption of battery power while it is on (active).
  • Page 50 Turning off the GPS receiver completely causes its icon to disappear from the main navigation screen. Attempting to enter the detailed information on GPS status (MENU → SETUP → GPS ) will display the message "Option currently not available" ‘ButtonSens+’ option Possible settings: enabled (yes) or disabled (no).
  • Page 51 This option requires a longer explanation. All earlier versions of the ENC3 had a default method of switching on by pressing both buttons simultaneously. Such a mechanism was dictated by the need to avoid accidental (unintentional) activation of the device due to shock or vibration.

  • Page 54: Compass Calibration

    Declination - The magnetic declination is a constant value, depending on your geographical region. It can be obtained from many sources for example https://www.ngdc.noaa.gov/geomag/calculators/magcalc.shtml#declination Deviation – A constant value that will be added to the heading shown on the display (and to all position calculations). The deviation is a constant value caused by magnetic elements near the navigation device, that cannot be removed.
  • Page 55 Compass calibration - current values Compass calibration – previous calibration values The compass calibration current values contain the following information: Age - calibration age (time elapsed since the last calibration). NOTE - if the clock is or was incorrectly set during calibration, the indication may be incorrect.

When Current is highlighted, pressing the new button starts the compass calibration process. When the Previous field is highlighted, we can see the calibration settings that the console had previously.
  • Page 57 The screen for restoring the calibration to the factory values ENC2 window during calibration While calibrating the compass, you should slowly- without rapid movements- turn it in all possible directions ("tilting the eighths while turning around"). The screen displayed during this operation has not changed from the previous version. The only addition is the digital "calibration progress percentage"...
  • Page 58 Preview of current values from sensors The last function available in the compass calibration menu is the function of displaying the current values measured by the sensors of the ENC console. We activate this function by highlighting Raw data on the compass calibration screen. By pressing the lower button of the console, we change the view of the previewed data, as shown in the figures below: Accelerometer raw data Magnetometer raw data...
  • Page 59 Euler angles Gyroscope raw data The data of the magnetometer (Mag) can be used, for example, when looking for a good place to mount the ENC console. If the total value of the magnetic field (Field) oscillates, for example, around the number 47.7uT (as in the picture above) and we bring our ENC console closer to the scooter, we can observe a change in the Field value.

  • Page 60: Enc Installation Angle (Install Angle)

    If the Euler angle indications do not work as described, the device must be reset to factory settings and then carefully calibrated from the beginning. When that doesn't help, the ENC console should be returned for service. 23. ENC installation angle (Install angle) The last new feature available in the compass calibration menu is the Install angle feature.
  • Page 61 Analyzing some less typical cases, we concluded that for some divers, due to their specific habits or specific diving conditions - this simplified system is insufficient and may lead to errors in determining the direction of flow, which also tend to accumulate. Therefore, in the current software version, the installation angle issue has its own configuration section and it is required that the user correctly configure this parameter.
  • Page 62 may vary depending on user requirements. If we tilt the console a bit, then when our scooter is set differently than straight, the compass direction measured by the ENC console does not coincide with the direction of the scooter movement. No DPV tilt- correct readings DPV is tilted- changed readings The error will occur in case the ENC2 console does not compensate its indications.
  • Page 63 The new software version allows the user to fully control all the necessary parameters. To set this parameter, go to MENU → SETUP → Compass → Install angle. The ENC console display will show the following:: The current value of Install angle is shown Measurement of non-standard Install angle value - first stage.

  • Page 65 If so, our Install angle has been set correctly. By tilting the scooter to the right or left, we will see that the white dot is moving in the opposite direction. If the white dot is low, the Install angle selected by us is too small (e.g. we set -15 and it should be -30 degrees) The reverse is true if the white dot is too high.
