3.3 Temperature Calibration
3.3.1 With Temperature probe For Preselected Curve
The temperature sensor included with your meter is factory-calibrated. Over
time, the temperature calibration may drift and require recalibration. If you
replace the probe you should calibrate temperature probe prior to Conductivity
or TDS calibration.
1. Connect your temperature probe to the meter. Press MODE key to enter
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 probe and
thermometer in a constant temperature bath.
3. Press CAL key to enter temperature calibration mode. The LCD shows
“CA” momentarily and the displayed reading flashes.
4. Press
∆∆∆∆
(up) or
∇ ∇ ∇ ∇
(down) key until the display shows the correct
temperature. The arrow keys will scroll to the maximum allowable value of
±5
o C.
5. Press ENTER key to confirm calibration. The LCD displays “CO”
momentarily, and the meter reverts to measurement mode.
