thermal equilibrium. The display will then show the measurement

automatically temperature compensated for temperature with the

appropriate indication among the following:

TAKING TEMPERATURE MEASUREMENTS

• Submerge the tip (4cm/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 HI 700661

Cleaning Solution.

• After measurements have been completed, the instrument

should be switched off, and the probe cleaned and covered

with the protective cap.
