To Standardize the meter in the Manual Standardization Mode
1. Insert the DO into your choice of standard.
2. Touch std on the DO or BOD Measure screen to access the
standardized screen
3. Touch clear to delete a previous standardization.
OR
If the screen says “Not standardized” proceed to step 4.
4. Touch std again to initiate standardization
5. Using the touch pad, input the value of the DO standard in %
Saturation, or mg/L.
6. Touch enter to accept the DO value of the standard.
MEASURING will flash until the signal is stable. The meter will
accept the value once it recognizes that the reading is stable. At
that time, STABLE will appear on the screen at this time. A
beaker icon and the entered DO value will also appear on the
screen at this time. The meter will then return to the measure
screen.
Barometer Calibration
The CyberScan DO 5000 internal barometer provides pressure
compensation for both auto and manual standardization. For most
accurate results, the barometer reading should be checked
occasionally for accuracy. If the meter’s barometer reading is
inaccurate, refer to DO setup to calibrate the barometer.
