General Overview

Congratulations on the purchase of your Field Scout™
SoilStik™ Pro Meter. This manual describes how to
use your pH meter and keep it working accurately.
Read the manual thoroughly in order to make effective
use of your meter.

The SoilStik delivers high quality answers, with an
accuracy of +/- 0.01 pH units. This self-contained digital
meter allows you to test the pH levels in water, soil, and
other liquids. The replaceable sensor makes the
measurement of small samples much more convenient.
The sensor provides a visual indication of when
replacement is due.

The meter has a two-point, automatic calibration (pH 4
and 7), with a range of pH 2.0-12.0. The display will
show your results to a resolution of 0.01 pH units.

Getting Started

• New meters are shipped with a battery insulating

strip. Remove this strip before attempting to power
up the meter. The battery compartment is ac­cessed by removing the cap at the top of the meter.

• Remove the cap from the bottom of the SoilStik to

expose the electrode glass surface and reference
junction.

• Before first use, or after extended storage, soak the

electrode (with its cap removed) in pH 4 solution for
about 10 minutes.

LCD Display

Messages

In addition to displaying the pH and temperature read­ings, the LCD of the SoilStik can also display:

- CAL reminder
If the SoilStik is powered up in pH mode 15 times with­out being calibrated, the CAL reminder symbol appears
on the LCD indicating that the SoilStik may require cali­bration. Some applications may require recalibration of
the electrode more frequently than others. The CAL
display is simply a reminder and will turn off when the
pH electrode is recalibrated.

- RENEW reminder
The RENEW symbol appears when the output of the
pH electrode fails an internal diagnostic test. A flashing
RENEW warning indicates that the probe may
ing the end of its useful life. Try to clean and recalibrate
the meter. If the RENEW symbol remains flashing, Re­move the battery holder, remove and replace the bat­teries and re-insert the battery holder (see p. 12). If this
does not cause the RENEW symbol to disappear, re­place the electrode.

- HOLD
While in measurement mode, pressing the MODE but­ton causes the meter to hold the value on the LCD.
The reading is also stored in short-term memory (see p.

10)

- BAT
Indicates that battery power is low. To preserve battery
life, the meter automatically powers off after 10 minutes
of inactivity.
