WaterMonitor as an input.

Update rate

When plugged in, the Water Monitor refreshes readings every second. When on

battery power, the update interval is customizable, by using the Update setting in

the menu. Setting a longer interval results in improved battery life, at the cost of

slower updates. If you're monitoring long-term system health, a longer update

interval allows you to go longer between battery changes. When plugged in, the

user-customizable setting is ignored.

Calibration

pH, ORP, and EC can be calibrated by selecting their respective calibration items

in the menu. (Press forward on the control switch, select the item you wish to

calibrate using up and down, then press forward to start). Each calibration screen

displays instructions on how to perform the calibration. Note that you need

calibration solutions (eg pH buffers, conductivity standards etc) to initiate

calibration. If you wish to revert to default calibration (and other default settings),

you can select Reset all from the menu.

pH calibration uses either 2 or 3 points: 2-point calibration models pH as a linear

relationship with probe output voltage – this is good enough for most uses. 3-

point calibration account for nonlinearity in readings – this is suitable for scientific

measurements. You can read about how pH calibration works from our blog article

on the subject: https://www.anyleaf.org/blog/how-to-calibrate-ph-sensors.

EC and ORP calibration is simpler, as they each use single-point calibration. They

both use a linear model between the calibration point, and 0. ORP calibration

maps measured voltage to ORP voltage (They should be very similar), and EC

calibration compensates for imperfections in the probe and measuring setup.

pH and ORP probes need to be re-calibrated periodically, as ion-selective probes

like this drift over time. More the purpose of hydroponics or aquarium monitoring,

you can calibrate once every few months. EC probes shouldn't drift over time, and

you may be able to get away with never calibrating, or calibrating once for your

probe.
