If you are calibrating a HI 8931A or
HI 943500A using HI 7030 (12.88 mS/cm
@25°C) as buffer solution, turn the SLOPE
trimmer to display "
12.88
mS", with a ref-
erence temperature of 25°C (77°F).
If you prefer a reference temperature of
20°C (68°F), turn the SLOPE trimmer to
display "
11.67
mS".
of the calibration solution at 25°C (77°F),
i.e.:
80.0
mS using HI7034 with HI943500A
12.88
mS using HI7030 with HI943500B
1413
µS using HI7031 with HI943500C
84.0
µS using HI7033 with HI943500D
• The calibration is now complete and the
instrument is ready for use. All subse-
quent measurements will now be compen-
sated to 25°C (77°F).
• If the instrument will not calibrate refer to
the Probe Maintenance and Cleaning sec-
tion (see page 46).
