1.0 Introduction

The Bluelab Soil pH Meter has two press buttons; ‘calibrate’ and power. The power button

requires a short press; release in about one second. The ‘calibrate’ button requires a long

press; hold for at least three seconds and release when the display starts ﬂ ashing.

Turning the soil pH meter on and off

A short press of the power button will turn the soil pH meter on. The soil pH meter

automatically turns off after approximately four minutes if no buttons are pressed.

If the soil pH meter turns off before the reading is taken, short press the power

button to turn the soil pH meter on again.

2.0 Preparing for use

The following tasks must be performed before the Bluelab pH Meter is used for the

ﬁ rst time.

Insert batteries.

See section 8.0.

Connect soil pH probe

Connect the soil pH probe to the soil pH meter

by lining up the lugs of the BNC ﬁ ttings. Fasten

securely by pushing the pH probe connector on

and twisting one quarter turn.

Remove the storage cap

Remove the pH probe storage cap by gripping

the top of the cap and gently twisting the base

one rotation clockwise to loosen slightly. Next

slowly slide the cap off the pH probe. DO NOT

completely remove the base of the cap from the

top of the cap.

CAUTION: When the soil pH probe is not in use,

add enough Bluelab pH Probe KCl Storage

Solution to the storage cap so the probe tip is

covered. Then replace the cap and store in a

secure place.

DO NOT use RO (Reverse Osmosis), Distilled

or De-ionized water. Pure water changes

the chemistry in the reference, causing the

probe to die.

Calibrate the pH

Calibrate the soil pH meter by following the

instructions in section 3.0 of this manual.

This must be done before the

soil pH meter is used for the ﬁ rst time.
