Technology Made Easy ...
The PC6000, CON6000, PC6500 and PCD6500 meters allows you to measure conductivity,
resistivity, TDS (total dissolved solids) and salinity. Each mode is independent from one another
and needs to be standardized separately. However the basic procedure for standardization and
measurement is similar for each mode. This manual will focus on conductivity standardization and
measurement with the variations for other modes noted. Each measuring mode has four
measuring ranges.
Conductivity: 0 to 200.0 µS, 200.0 µS to 2.000 mS, 2.000 to 20.00 mS, and
20.00 to 500.0 mS.
Resistivity: 0 to 20.00 KOhms, 20.00 to 200.0 KOhms, 200.0 KOhms to 2.000 MOhms,
and 2.000 to 100.0 MOhms.
TDS: 0 to 200.0 x TDS factor ppm, 200.0 x TDS factor to 2000 x TDS factor ppm, 2.000 x
TDS factor to 20.00 x TDS factor ppt, and 20.00 x TDS factor to 200.0 x TDS factor ppt.
Salinity: 0 to 0.094 ppt, 0.094 to 1.000 ppt, 1.000 to 11.50 ppt, and 11.50 to 90.00 ppt
Before measuring conductivity, resistivity, TDS or salinity, you will need to standardize the meter
using standards with known conductivity, resistivity, TDS or salinity values. This meter can
perform a single- or multi-point standardization. You will need to set your meter to single- or multi-
point calibration in the Setup mode for conductivity, resistivity, TDS or salinity. You may also use
the Setup mode set conductivity to auto standard recognition to recognize preset values (84 uS,
1.413 mS, 12.88 mS and 111.8 mS).
The meter will continually monitor the conductivity (resistivity, TDS or salinity) reading in this
mode and will not lock onto a single reading. However, once the reading has become stable,
STABLE will be displayed (unless the Stable indicator has been turned OFF in the Setup mode).
Remember to setup your measuring mode parameters. Refer to the setup section for the
particular mode you will be measuring.
