5.7 Pressure / Depth Units
It is also possible to present the data in units of metres or feet of seawater
calculated using the TEOS 10 Simple Pressure / Depth relationship, which assumes
“standard”
water density
Local Latitude is required (#016;nn.nnn)
Code
Description
#052;n
Set calibrated units as follows
where n=
0 = dBar (d)
1 = Metres (M)
2 = Feet (f)
Example: #052;1
sets the units to metres (M)
#053
Read pressure unit set
#083;n
Set the number of decimal places for Pressure / Depth output
where n = 1 to 3
#084
Read the number of decimal points in pressure |depth output
5.8 Set Latitude
This is required for an accurate pressure / depth conversion - the relationship is partially dependent
on local gravity, which varies with distance from the equator
Code
Description
#016;nn.nnn
Set the local Latitude in decimal degrees
Positive / negative signing for North / South of the equator is not relevant
Example: #016;50.426
Sets latitude to
50.426° North (50° 25’ 34”)
#017
Read the Latitude set in the instrument
