STEP 9 - Placement of probes
Both the pH and conductivity/temperature probes
require submersion in the liquid for measurement.
1. Fit the (optional) pH probe holder to the stem
of the pH probe using a gentle twisting
motion.
2. Place the pH Probe into the reservoir and push
the suction cup onto the side of the reservoir
but far enough down so the probe tip is in the
solution. The holder prevents damage to the
pH probe from banging onto the side of the
reservoir with movement of the solution.
3. Place the conductivity probe into the
reservoir.
NOTE: Do not pour concentrated nutrient solution
or pH adjuster directly onto probes when in the
reservoir.
STEP 10 – Set Alarms (optional)
The alarm function warns you when the solution
deviates from the desired levels you have chosen
for each measurement. When an alarm condition is
present, the display of the affected measurement
will flash. If the measurement changes back to
within the limits you have chosen, the flashing will
stop.
There are two ways to set the alarm, ‘quick-set’ or
‘Detailed’.
Alarm ‘Quick-set’
This allows you to quickly set the ‘alarm HIGH’ and
‘alarm LOW’ values for all of the three
measurements. The table below shows the values
that are pre-set when ‘quick-set’ is used.
NOTE: Before you set the alarms, ensure the
solution in the tank/reservoir is adjusted to the
desired/actual levels for all three parameters and
that these are displayed in each of the windows.
