Note…
If the ATC Temperature Probe is not connected, the display will
read as in Fig. A. No measurement can be performed until the
ATC jack is connected.

Auto Ranging:
The meter will measure conductivity in the μS/cm and mS/cm
scales and will calculate the TDS value in ppm or ppt according to
the TDS conversion coefficient that was entered in the TDS Factor
set up procedure.
During measurement and calibration this meter will automatically
select the correct range. Measurement ranges are as follows:
Conductivity
TDS
1
0.00-19.99 μS/cm
0.00-9.99 ppm
2
0.0-199.9 μS/cm
10.0-99.9 ppm
3
0-1999 μS/cm
100-999 ppm
4
0.00-19.99 mS/cm
1.00-9.99 ppt
5 0.0-199.9 mS/cm
10.0-199.9 ppt
