probe with the CELL K= staying on. Adjust the probe constant
to a known value by pressing the “Up” or “Down” keys. You
can now input the K value (from 70% to 130% of the probe
basic cell constant). Press the “Enter” key to exit calibration
and return to normal operation.
B. Conductivity, Salinity, TDS Measurements
1. Turn the unit on. Connect the conductivity probe to the unit.
2. Press “Mode/Clear” key to go to conductivity/salinity/TDS
mode. “ATC” icon, “uS/cm (ppt/mg/L)” icon and “AUTO” icon
will lit up. Place the probe in the solution to be measured.
Immerse the probe (at least 2” to 3” or 5 to 7cm from the tip).
Shake the probe lightly to remove any trapped air bubbles in
the conductivity cell.
3. Allow sufficient time for the display to stabilize. The meter
will display the conductivity/salinity/TDS value of the sample at
the displayed sample temperature.
[Note: Press “Mode/Clear” 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.]
C. Save, Recall and Delete Data
1. Saving readings to memory.
a. In the measure modes, press and hold “Enter” key for 2
seconds to save data. The “ID” icon and number with the
corresponding site number will lit up for a brief moment to
indicate a successful data save. Saving is now complete.
b. If “Full” lit up, this means that all 750 data saving sites
are used up. No new data can be saved until existing saved
data are deleted.
2. Recalling readings from memory.
a. Press “Mode/Clear” key until “dAtA rCL” shows. Press
"Enter" key to go into “Recall” mode.
b. To view data, press “Up” or “Down” key to select the
storage site number and displays the corresponding record.
c. Press “Mode/Clear” key to exit “Recall” mode.
