3.3.2 Without Temperature probe (no ATC)
If no temperature probe is used, the meter compensates for Conductivity or
TDS response based on a new calibrated temperature value manually set by
you or at 25
o C (factory default).
1. Press MODE key to enter into Temperature mode until “ o C” shows in the
LCD.
2. Compare displayed value to a NIST certified thermometer or other
thermometer known to be accurate.
3. Press CAL key to enter temperature calibration mode. The LCD shows
“CA” momentarily and the displayed reading flashes. Note that this
displayed value should either be 25.0
o C or last set temperature value.
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.
CA 25.0 o C
CO 25.0 o C
