SBE 52-MP
The SBE 52-MP is able to directly output data that is already converted to engineering units (pressure in decibars),
using calibration coefficients that are programmed into the instrument. The SBE 52-MP does not use a .con file.
Follow this procedure to correct the pressure:
1. With the SBE 52-MP in the air, place it in the orientation it will have when deployed.
2. In SEATERM, set the pressure offset to 0.0 (POFFSET=0).
3. Acquire data using the TP command.
4. Calculate offset = (0 – instrument reading).
5. Enter the calculated offset in the SBE 52-MP (use POFFSET= in SEATERM).
Offset Correction Example:
Pressure displayed at elevation is -1.655 db. Offset = 0 – (-1.655) = + 1.655 db
Enter offset in the SBE 52-MP.
SBE 39-IM
The SBE 39-IM directly outputs data that is already converted to engineering units (pressure in decibars), using
calibration coefficients that are programmed into the SBE 39-IM. The SBE 39-IM does not use a .con file.
Follow this procedure to correct the pressure:
1. With the SBE 39-IM in the air, place it in the orientation it will have when deployed.
2. In SEATERM, set the pressure offset to 0.0 (#iiPOFFSET=0).
3. Acquire data using the #iiTP command.
4. Calculate offset = (0 – instrument reading).
5. Enter the calculated offset in the SBE 39-IM (use #iiPOFFSET= in SEATERM)
Offset Correction Example:
Pressure displayed at elevation is -1.655 db. Offset = 0 – (-1.655) = + 1.655 db
Enter offset in the SBE 39-IM.
