Allow temperature reading to stabilize, press "CAL" key to
enter the calibration mode. The "CAL" icon appears on the
LCD. Press "MODE" key to sequentially view previous
calibration settings.
TDS
TDS is determined by multiplying conductivity (mS) by a TDS
factor. The default factor value is 0.65. To change the TDS
factor, use the "UP" and "DOWN" keys to adjust the value
between 0.30 and 1.00. Press "ENTER" 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
"ENTER" key, any changes made will be cancelled and the
previous calibration settings will be retained.
CELL
Use "UP" and "DOWN" keys to select cell constant between
"C0.5" or "C0.1" on the secondary display. Press "ENTER"
key to confirm selection and the unit will then automatically go
into the next calibration parameter. If "MODE" key is pressed
instead of the "ENTER" key, any changes made will be
cancelled and the previous calibration settings will be
retained.
Temperature Coefficient
The unit uses the temperature coefficient to calculate
temperature compensated conductivity. The default value is
1.91%. To change the temperature coefficient, use the "UP"
and "DOWN" keys to adjust the value between 0 and 4.00%.
Press "ENTER" 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 "ENTER" key, any
changes made will be cancelled and the previous calibration
settings will be retained.
Temperature Reference
The unit uses the temperature reference value to calculate
temperature compensated conductivity. The default value is
25
℃
. To change the temperature coefficient , use the "UP"
and "DOWN" keys to adjust the value between 15
℃
and 25
℃
. Press "ENTER" 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 "ENTER" key, any
