Note: If the display shows range limit value blinking, there is an
over-range condition. Select the next higher range.

••
• Allow a few minutes for the reading to stabilize. The LCD will
display the temperature compensated conductivity reading.
TAKING CONDUCTIVITY MEASUREMENTS WITH HI 2315
••
••
• Switch the instrument on by pressing ON/OFF.
••
••
• Immerse the probe in the solution while
completely submerging the holes of the sleeve.
Tap the probe lightly on the bottom of the
beaker to remove any air bubbles trapped
inside the sleeve.
••

• Adjust the Temp. Coefficient knob to the temperature coefficient
value of the solution (see “Determination of the Temperature
Coefficient of a Solution” section for details).

OPERATIONAL GUIDE
Power connection
Plug the 12 Vdc adapter into the power supply socket.
Note: Make sure the main line is protected by a fuse.
Probe connection
Connect the conductivity probe to the proper socket on the rear panel.
Note: Make sure that the instrument has been calibrated before
taking any measurement (see “Calibration” section).
Note: If possible, use plastic beakers to minimize EMC interferences.
