• Select the appropriate measurement range (EC or TDS).
• Wait a couple of minutes for the temperature sensor to reach
thermal equilibrium. The display will then show the measurement
automatically temperature compensated for temperature with the
appropriate indication among the following:
“µS” symbol indicates the meter is in
EC mode;
“mg/L” symbol indicates the meter is
in TDS mode.
TAKING TEMPERATURE MEASUREMENTS
• Submerge the tip (4 cm/ 1½”) of the
probe into the sample to be tested.
• Select the °C mode.
• Stir briefly and wait a couple of minutes
for the reading to adjust and stabilize.
The display shows the temperature value.
Notes: • If the display shows only a “E”
on the right side of the LCD, the
reading is out of range.
• It is recommended to clean
often the probe with HI700661
Cleaning Solution.
• After measurements have been
completed, the instrument should
be switched off, and the probe
cleaned and covered with the
protective cap.
