Calibrating a Conductivity (EC) Probe
Atlas EZO EC circuits can be calibrated 2 ways:
One Time Dry Calibration
2 Point Calibration
A One Time Dry Calibration, is just that. It is only performed ONCE, when a probe is new and being used for the first time.
For regular maintenance calibrations, i.e. yearly, always use the 2 Point Calibration.
For a 2 Point Calibration, you use a suitable calibration solution, one of each of Low and High, which you will have selected
on the CALIBRATE ATLAS PROBE screen.
The available options for calibration solutions are:
Low
1,413 µS/cm (micro-Siemens per cm)
5,000 µS/cm (micro-Siemens per cm)
12,880 µS/cm (micro-Siemens per cm) (Atlas solution)
High
80,000 µS/cm (micro-Siemens per cm) (Atlas solution)
111,800 µS/cm (micro-Siemens per cm)
150,000 µS/cm (micro-Siemens per cm)
Selecting Conductivity (EC), will take you to the
screen at left, CALIBRATE CONDUCTIVITY.
When you calibrate the Conductivity you should
first clear the calibration data on the circuit, this is
only required if you were playing and didn’t do a
proper calibration but doesn’t hurt to do it every
time.
The Conductivity circuit can be calibrated using a
One Time Dry Calibration or 2 Point Calibration
process, you can find the buffer solution required
for each point by referring to the CALIBRATE ATLAS
PROBE screen.
Select the calibration type you want to perform and you’ll be taken to the next step.
After you select the calibration type you want to
perform you’ll see the screen to the left, or one
very similar.
At the top it’ll tell you how many points the
calibration is, in this case, Two Point Calibration,
and which step you’re on.
Below this, you’ll see instructions to carry out the
calibration.
Follow these steps and press OK after waiting 2+
minutes.
