HI 8614, HI 8614L
pH CALIBRATION WITH FIXED TEMPERATURE
COMPENSATION (HI 8614 family)
• Take the temperature of the buffer
solutions using a Checktemp or a
thermometer with a resolution of at
least 1 °C.
• Connect the appropriate resistor
to the “TEMP. PROBE” terminals
(see page 8) depending on the
temperature of the calibration solution.
• Follow the procedure as outlined in the calibration with automatic
temperature compensation and use the thermometer reading to
adjust the trimmer until the ammeter reads the value according
to the following table.
