5.4 Using Manual Ranging Function
Your meter automatically selects the range in which your readings appear. The manual
ranging function lets you select the specific range (and corresponding resolution) that you
want to work in:
CON 400 and CON 410 meters: CON 410 meter:
1. 0.00 --- 19.99 μS 1. 0.00 --- 9.99 ppm
2. 0.0 --- 199.9 μS 2. 0.0 --- 99.9 ppm
3. 0 --- 1999 μS 3. 0 --- 999 ppm
4. 0.00 --- 19.99 mS 4. 0.00 --- 9.99 ppt
5. 0.0 --- 199.9 mS 5. 0 --- 100 ppt
(up to 199.9 ppt depending on TDS factor
setting)
1. To select the desired measuring range, press the
RANGE key while in Measurement mode. The first
range will appear on the display and the “MEAS”
indicator blinks.
2. Press the RANGE key again (if needed) until desired
range is selected.
3. To re-select the Auto-ranging function, repeatedly
