LaMotte CDS 5000 Conductivity Meter - Manual (Page 7)

CALIBRATING
The CDS 5000 is precalibrated at the factory; set both the TDS knob and
the SLOPE knob to the 12 o’clock position and proceed. This procedure
will give results within
±10% of the actual reading. For more accurate
results, follow the procedure below.
1. Press “°C” button to turn the meter on.
2. Set TDS knob to the 12 o’clock position.
3. Insert temperature and conductivity probes at least
1
2
“ into
conductivity standard.
4. Gently stir with conductivity probe until reading stabilizes. Press
“
mS/ppm” or “mS/ppt” button.
5. Adjust SLOPE knob until display reads conductivity of chosen
standard. The CDS 5000 is now calibrated and ready for use.
LaMotte offers several ranges of conductivity standards. Choose the
standard most appropriate for your testing needs and order using the four
digit code number listed.
