To select the desired measuring range, press the RANGE
key while in Conductivity (or TDS) measurement mode.
The first range will appear on the display. The “MEAS”
indicator blinks, and the “Range” number flashes briefly
in the lower display.

TDS
r1 =
0.00-19.99 µS
0.00-9.99 ppm
r2 =
0.0-199.9 µS
10.0-99.9 ppm
r3 =
0-1999 µS
100-999 ppm
r4 =
0.00-19.99 mS
1.00-9.99 ppt
r5 =
0.0-199.9 mS
10.0-199.9 ppt
