TDS FACTOR
:
The default factor value is 0.65. To change the TDS factor,
use the “Store” and “Scroll” keys to adjust the value
between 0.30 and 1.00. Press “Hold” key to save the new
value and the unit will automatically go into the next
calibration parameter. If “Mode” key is pressed instead of
the “Hold” key, any changes made will be cancelled and
the previous calibration settings will be retained.
TEMP. COE.:
The unit uses the temperature coefficient to calculate
temperature compensated conductivity. The default value
is 1.91%. To change the temperature coefficient, use the
“Store” and “Scroll” keys to adjust the value between 0
and 4.00%. Press “Hold” key to save the new value and
the unit will automatically go into the next calibration
parameter. If “Mode” key is pressed instead of the “Hold”
key, any changes made will be cancelled and the previous
calibration settings will be retained.
TEMP. REF.:
The unit uses the temperature reference value to calculate
temperature compensated conductivity. The default value
is 25°C. To change the temperature coefficient, use the
“Store” and “Scroll” keys to adjust the value between 15°C
and 25°C
. Press “Hold” key to save the new value and the
unit will automatically go into the next calibration parameter.
If “Mode” key is pressed instead of the “Hold” key, any
changes made will be cancelled and the previous
calibration settings will be retained.
4. Immerse the probe in a standard of known conductivity,
preferably a standard in the middle range of the solutions to
be measured. Immerse the probe (at least 2” to 3” or
5~7cm from the tip) into standard solution without touching
the sides of the calibration container. Shake the probe
lightly to remove any air bubbles trapped in the conductivity
cell.
