3.5.1
With Temperature probe
The temperature probe (EC-PH5-TEM01P/ 35613-05) provided with the meter is
factory-calibrated. Over time, temperature calibration may drift and require calibration. If
there is a need to replace with the new probe you should calibrate the temperature
probe prior to pH calibration.
1. Connect your temperature probe to the meter. Press
MODE
key to enter the
Temperature mode until “
o
C
” annunciator appears in the LCD.
2. Compare the displayed value to a NIST certified thermometer or other thermometer
known to be accurate. For best accuracy, place both the probe and thermometer in
a constant temperature bath.
3. Press
CAL
key to enter temperature calibration mode. The LCD shows “
CA
”
momentarily and displayed reading flashes.
4. Press and keys (for Ion 6) or
INC
key (for pH 5/6) until the LCD display shows
the desired temperature. The meter allows an adjustable maximum value of ± 5
o
C
from factory default.
5. To cancel or abort this operation, press
CAL
key. Note no new value will be stored
into its meter‘s non-volatile memory. To confirm calibration, press
ENTER
key. The
LCD displays “
CO
” momentarily, and the meter reverts to measurement mode.
