Calibration
• Pressure Transducer
• The offset, slope, and date of the last calibration are
displayed.
• The Measured field is in the slope calibration. See
Section 5.1.1
for instructions.
• The Calibrate Offset and Calibrate Slope buttons
are used to calibrate the pressure transducer. See
Section 5.1.1
for instructions.
• Conductivity Cell
• The offset, slope, and date of the last DS5 calibration
are displayed.
• The Calibrate Offset or Calibrate Slope buttons are
used to calibrate the cell. See Section 5.1.2
for
calibration instructions.
• Click the Details button to open a window that shows the
factory-set calibration values, the current values, and the
previous set of calibration values. The factory and last set of
calibration values can be downloaded from this window.
Diagnostic
• The last calibrated pressure and conductivity variance,
minimum, and maximum readings for the DS5 are
displayed.
• The Start and Stop buttons start and stop the readings.
• To determine the conductivity variance of the electronics
alone, select the Dummy Cell box and then click Start. The
variance reading should be less than 1
µS.
