Conductivity Calibration
NOTE:
These meters are factory set to compensate for
temperature differences at a temperature coeffi-
cient of 2% per °C. For most applications this will
provide good results. See Program P1.1 (page 16)
to set temperature coefficient to a different value.
See Addendum 3 “Calculating Temperature
Coefficients”, page 28 for information on deter-
mining the appropriate temperature coefficient for
your solution.
1.
Press the ON/OFF button to turn on the meter, if
necessary.
All the LCD segments display for a few
seconds. When you turn the meter on, the LCD enters
the conductivity measurement mode.
See Figure 6.
2.
Press MODE to select conductivity mode, if
necessary.
The COND indicator should show at the
bottom of the display.
3.
Pour a small volume of your calibration standard
into a clean container.
There should be enough
standard solution to immerse the tip of the conductivity
cell above the air holes about
3
⁄
4
" from the bottom of
the probe.
4.
Rinse your probe with deionized water, then in a
small amount of calibration standard.
5.
Immerse the probe into the container of standard
solution, and press CAL.
The CAL indicator will flash
in the upper right corner of the display.
See Figure 7.
6.
Allow the probe time to stabilize.
NOTE:
When dipping the probe into the sample,
make sure the tip of the probe is completely
immersed into the sample.
Also make sure there
are no air bubbles trapped in the slot of the probe,
or your measurement will be inaccurate. To
remove air bubbles, tap the probe gently while the
probe tip is submerged.
