Pressure Cal (% saturation mode only)
The DO 2700 includes a built-in barometer that is
factory calibrated. While frequent pressure
adjustment is not required, adjustments can be
made in the Adjusted Pressure field. The
Measured Pressure is the active pressure value
measured by the DO 2700.
Note: if adjusting, “true” barometric pressure—that
has not been corrected to sea level, must be used.
Pressure reported by weather services are almost always corrected and therefore
are not appropriate for entry in the adjusted pressure field here.
Pressure Compensation (% saturation
mode only)
Select ENABLE or DISABLE.
Measure Unit (concentration mode only)
Select mg/L or ppm concentration units.
