AUTORANGING EC/TDS CALIBRATION The EC and TDS scales are autoranging. The meter automatically sets the scale with the highest possible resolution. By pressing ALT+FIXED, the autoranging feature is disabled and the current range is frozen on the LCD. "F1" symbol blinks on the LCD. To restore the autoranging option press ALT+FIXED again. Note: Autoranging is automatically restored if the RANGE key is pressed, if the setup or calibration modes are entered and if the meter is turned off and back on again.
III IV V In order to minimize any EMC interference, use plastic beakers. The meter uses 1.90%/ C compensation factor during calibration. If the setup item "tc" has been set to a different value, when exiting the calibration mode the value displayed on the upper LCD could be different from the nominal buffer value. It is possible to set the cell constant value directly without following the calibration procedure. To set the cell constant enter the setup mode and select "CEL" (see SETUP for details).
CONDUCTIVITY VERSUS TEMPERATURE CHART SETUP The conductivity of an aqueous solution is the measure of its ability to carry an electrical current by means of ionic motion. The conductivity invariably increases with increasing temperature. It is affected by the type and number of ions in the solution and by the viscosity of the solution itself. Both parameters are temperature dependent.
