NOTE: The number of items on this menu depends greatly on the sensors that are available and enabled on
your sonde. Below we describe every possible item on this menu. Your sonde probably may not have
every item described below.
To edit one of the following menu items choose the number or letter that corresponds to it.
TDS constant=0.65 This selection allows you to set the constant used to calculate TDS. TDS in g/L is
calculated by multiplying this constant times the specific conductance in mS/cm. This
item will only appear if the conductivity sensor is enabled in the “Sensors enabled”
menu. See Section 53, Principles of Operation for more information on the TDS
parameter.
Salinity=0
This selection allows you to input a manually-acquired value of salinity for calculating
other parameters such as DO mg/L and depth. This item is not used or displayed if the
conductivity sensor is enabled in the Sensors menu.
Pres=0 psi
This selection allows you to set a value of pressure for calculating other parameters like
salinity. This item is not used or displayed if the pressure sensor is enabled in the
Sensors menu.
Latitude=40
This selection allows you to input the global position (latitude) where the sonde is
sampling. The units are degrees. For accuracy, enter the decimal equivalent to indicate
degrees and minutes. For example, enter 41
o 30 ' as 41.5. This value is used in the
calculation of depth or level to account for global variations in the gravitational field.
This item will only appear if the pressure sensor is enabled in the Sensors menu.
Flow Setup… This selection allows you to setup the sonde to output flow information. See Appendix F,
Flow for detailed information on how to setup the Flow parameter. This item will only
appear if the sonde has shallow vented level.
Altitude=0
This selection allows you to input the local altitude (relative to sea level) where the sonde
is sampling. The units are feet. You may enter positive or negative values (range is -276
to 29028) to represent altitudes above or below sea level. This value is used in the
