3.5.5 Calibrate
Click on the Calibrate button in the Scuba pull-down menu to get a screen listing all the parameters that can be calibrated
in a Scuba. Click on the parameter you wish to calibrate to see its calibrate screen. This screen has calibration instructions
for the specific parameter and shows the current reading for that parameter.
If your calibration requires a calibration standard, type your calibration standard value where it says “ enter calibration
value ”. When the parameter reading has stabilized in the calibration solution, click on the OK button. If your calibration
has an acceptable SRF (Sensor Response Factor, an indication of the sensor condition (4.4); the calibration will be
accepted, and you will be returned to the home page. If you click on “ OK ”, the calibration will be accepted despite a
deviant SRF, and you will be returned to the home page). If you click on “ Cancel ”, you’ll go back to the calibrate screen.

How do I know if I need to calibrate?
The simple answer is that frequent calibration will give you better data. The more meticulous you are
with calibration, the better data you will gather. If you are uncertain whether you need to calibrate, check your
sensors against a known sample. If the reading is within the accuracy specification and/or your accuracy
expectations, there is no need to calibrate.
Experience and your program’s accuracy expectations will help determine calibration frequency for the various
sensors. If, for instance, your reservoir discharge is hovering near the regulatory minimum for dissolved
oxygen, you should pay special attention to DO calibration frequency and technique. On the other hand, if a
conductivity accuracy of +/- 10% is OK, you needn’t calibrate conductivity very often.
