TEMPERATURE
• Press the COND/TEMP key to display conduc-
tivity readings and select the appropriate
conductivity range
e.g. "19.99 mS" for HI7030/HI8030,
"99.9 mS" for HI7034/HI8034,
"1999µS" for HI7031/HI8031,
"199.9 µS" for HI7033/HI8033.
• Using a small screwdriver adjust the trimmer on the rear panel
until the display shows the conductivity reading at the tempera-
ture of the solution noted earlier (see the
conductivity vs. temperature chart on page
13) e.g. "11.19 mS".
Calibration is now completed and the instrument is ready for use.
TO CHECK THE CALIBRATION
• Press the COND/TEMP key to display the tem-
perature.
• Adjust the TEMPERATURE knob to display the
temperature of the calibration solution, i.e.
the temperature noted with the CHECKTEMP
or glass thermometer.
