5. Calculate the actual speed over the measured distance
(distance/time).
6. If the calculated speed is:
• The same as the current speed value, (noted during the
calibration run) then the calibration is correct at this speed,
so proceed to step 8 below.
• Not the same as the indicated speed:
– Calculate a new, corrected calibration factor, as follows:
actual speed x old calibration factor
new calibration factor =
indicated speed
– Use the UP and DOWN buttons to change the calibration
factor to the new calculated value.
7. Repeat steps 4 to 6, until the current speed values displayed
during the calibration run is the same as the calculated speed.
8. Press SAVE to save calibration factor and return to the speed
calibration page.
9. Repeat steps 3 to 8 for all calibration speeds.
Calibrating water temperature
You can calibrate the water temperature reading. This is done by
matching the temperature displayed by the instrument to a separate
reading taken with a thermometer.
You will need an suitable thermometer to measure the water
temperature.
With the list of transducers available displayed, from the Transducer
Setup menu.
1. Select the relevant conventional or smart transducer.
2. Select Current Temperature option.
3. Use a suitable thermometer to measure the water temperature.
4. Use the UP and DOWN buttons to match the displayed
temperature at the instrument to that measured by the
thermometer.
5. Press SAVE to save the setting.
