5.6 3.3 dPr (Barometric Pressure Adjustment)
Press .
Press or to select units; Hg (mm Mercury) or bAr.
Press to confirm.
Press or to adjust the value, press to accept.
5.7 3.4 SALt (Salinity Adjustment)
For best accuracy, enter the actual salinity value if your samples are at
least 0.1 ppt (100 ppm). Maximum adjustment is 50 ppt (50,000 ppm or
5% salt).
Press .
Press or to adjust the value (in parts per thousand).
Tip: 0.1 ppt = 100 ppm salinity
Press to confirm.
5.8 3.5 OFS (Offset Adjustment) from % mode
Use this feature to offset the meter’s value to another DO meter.
Using the % saturation mode, observe the reading a sample solution
after it has stabilized. Similarly, observe the reading of the same
sample using another DO meter as a reference. The probe of the
reference meter should be immersed in the same sample at the same
depth.
The DO 700 allows +/- 10.0% offset adjustment. Note that subsequent
user calibrations will reset the offset adjustment back to the factory
default value of 0.0 %.
Press .
Press or to adjust the % offset.
