1.0 Before fi rst use begins
ATTENTION: Salt-crust forming on the pH probe is normal. A small amount of
KCl solution from the storage cap/dibber may leak out leaving a salt-crust.
This does not affect the probe and is normal.
The following tasks must be performed before the Bluelab Soil pH Pen is used for
the fi rst time.
Check the soil pH probe tip is covered with KCl
storage solution
pH probes need to be be kept wet at all times.
Before you remove the storage cap/dibber, check
how much Bluelab pH Probe KCl Storage Solution
is in the cap.
a) Stand the soil pH pen upright. There should be
enough KCl storage solution to cover the pH probe
tip. If the probe tip is covered, go to steps 2 & 3.
b) If the probe tip is NOT submerged in KCl storage
solution, you will need to hydrate the soil pH probe
before use. Remove the storage cap (see secton
2.0), then go to section 3.0 for hydration steps.
Removing and replacing the storage cap/dibber
IMPORTANT: Pulling the cap off, or placing the cap on, without loosening fi rst will
break the probe. See section 2.0 for more details.
Calibrate the Soil pH Pen before the fi rst use to ensure accurate readings.
Go to section 11.0 for calibration steps.
2.0 Removing and replacing the storage cap/dibber
IMPORTANT: Always loosen the storage cap/dibber before removing or
replacing from the probe.
To remove the storage cap/dibber
a) Grip the top and twist the dibber a few
times to the left to loosen. You’ll know
the cap is loose when you can see a
gap between the cap and the dibber.
b) Slide the storage cap/dibber off.
c) Place cap upright, in a cup or similar
container so that the KCl storage
solution doesn’t spill out.
To replace the storage cap/dibber
Place the loosened storage cap/dibber
gently on the probe, sliding until it stops
moving up.
Grip the top and twist the cap to the right
until secure.
