Wait for the values of temperature and conductivity to stabilize
for a few seconds. Press the
“
Up
”
and
“
Down
”
keys to
adjust the reading of the display until it matches the value of the
known standard conductivity solution at 25
℃
. Press the
“Slope/Enter”
key to save and exit the calibration.
[Note:
If you want input
K value
directly, press the
“Slope/Enter”
key to go to the
K Value Input.]
K Value Input
The unit will display the cell constant value of the conductivity
probe with the
CELL K=
staying on. Adjust the probe constant
to a known value by pressing the
“Up”
and
“Down”
keys. You
can now input the K value (from 70% ~ 130% of the probe
basic cell constant). Press the
“Slope/Enter”
key to exit
calibration and return to normal operation.

Conductivity, Salinity, TDS Measurements
1.
Turn the unit on. Place the probe in the solution to be
measured. Immerse the probe (at least 2” to 3” or 5 ~ 7cm
from the tip). Shake the probe lightly to remove any trapped
air bubbles in the conductivity cell.
2.
Press
“Mode”
key to enter the desired measurement mode
(Conductivity, Salinity or TDS). The message“rAn9” may
appear briefly on the display indicating auto-ranging; this is
normal. Allow temperature to stabilize before taking
measurements.
