In addition to displaying the pH and temperature read-
ings, the LCD of the SoilStik can also display:
-
CAL
reminder
If the SoilStik is powered up in pH mode 15 times with-
out being calibrated, the
CAL
reminder symbol appears
on the LCD indicating that the SoilStik may require cali-
bration. 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 be near-
ing the end of its useful life. Try to clean and recalibrate
the meter. If the RENEW symbol remains flashing, Re-
move the battery holder, remove and replace the bat-
teries and re-insert the battery holder (see p. 12). If this
does not cause the
RENEW
symbol to disappear, re-
place the electrode.
-
HOLD
While in measurement mode, pressing the
MODE
but-
ton 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.
