MEASUREMENTS
Immerse the probe into the solution to be tested. The sleeve holes must be completely submerged. Tap
the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve.
If needed, press
RANGE
repeatedly until the desired range (EC, Resistivity, TDS, Salinity) is selected
on the LCD.
Allow for the reading to stabilize. The main LCD line displays the measurement in the selected range,
while the temperature is displayed on the lower LCD line.
EC range
The conductivity range is from 0 to 400 mS/cm . The actual conductivity range (the uncompensated
conductivity) is up to 1000 mS/cm. The instrument will display conductivity readings up to 1000 mS/cm.
Note: The symbol in front of the temperature reading means that the temperature can be
entered by the user (Manual option selected in SETUP, or temperature out of range).
