When the external sensor is used and connected to the device (

Calc. distance from = External log

), the calibration is 

used to get the best possible distance measurements. The sensor principle of operation is based on pulse counting. 

The sensor calibration factor equals the number of pulses which the speed sensor will produce while swimming a 100m 

distance. 
A typical value is 1490 pulses on a 100m distance. 
This calibration factor depends also on the sensor position on the DPV. To get best results, mark the sensor position on 

the DPV body and perform the calibration procedure as described below: 

-

 

Mark the START and STOP point on a straight, known distance (100-1900 meters) 

-

 

Go to 

SETUP -> Log/Speed -> Calibrate log

 (make sure 

Active log

 is set to 

EXT

 ) 

-

 

Enter the known calibration distance in the field 

log at: …

 

-

 

Below, you will see the actual calibration factor

 log 100m: 1490

. Make sure, the arrow points to this line, and 

press the lower button. 

-

 

The screen will show the message 

Press START and swim exactly …. m

 

-

 

Go to START, set the favorite speed on your DPV, press START (lower button) on the navigation console, and 

swim as straight as possible to the STOP point. The screen display will show the pulse counter, which should 

increase with time. 

-

 

When you reach the STOP point, press the lower button again. The new log calibration factor will be shown on 

the screen. 

Caution:

  The calibration procedure will fail, if the pulse count recorded during the procedure is far too low. In this case, 

the previous value will be shown in the calibration factor field (

log 100m: …. 

) 

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.
