Depth
NOTE: This calibration option is available only if your bulkhead is equipped with a depth sensor. The depth
sensor is located where the cable connects to the bulkhead
For the calibration, make sure that the depth sensor is clean and in air, not immersed in any solution. For highest
accuracy, keep the bulkhead still and in one position while calibrating.
NOTE: Cables 10 m and longer are supplied with a weight that can be attached to the sensor guard for sampling
at water depths 10 m and greater.

NOTE: Depth offset allows you to set the depth measurement
to something other than zero. If the depth offset is used,
the depth measurement will be adjusted by the offset
after calibration. Enter the altitude and latitude of your
sampling location to increase the accuracy of your depth
measurement.
