EC range
The conductivity range is from 0 to 400 mS/cm . The actual conductivity
range (the uncompensated conductivity) is up to 1000 mS/cm. The
instrument will display conductivity readings up to 1000 mS/cm.
Note: The symbol in front of the temperature reading means that the
temperature can be entered by the user (“Manual” option
selected in SETUP).
Resistivity range
The reciprocal of the conductivity of a material is the resistivity.
TDS range
A conductivity measured value can be corrected to a total disolved solids
value using the TDS factor (value entered in SETUP).
Salinity
The salinity is derived from the conductivity of a sample.
The percent of salinity in a sample is depending of the sample and on the
salinity coefficient.
The EC, Resistivity and TDS scales are auto-ranging. The meter automatically
sets the scale with the highest possible resolution.
By pressing Lock, the auto-ranging feature is disabled and the current
range is frozen on the LCD.
The “Range: Locked” message is displayed. To restore the auto-ranging
option press AutoRng functional key again.
The auto-ranging mode is also disabled by selecting a “fixed range” in
the SETUP menu. While in fixed range mode the instrument will display
the readings with the fixed resolution. Maximum 6 digits can be
displayed.
The top of the fixed range is displayed blinking when the reading exceeds
this value.
To disable fixed range mode enter SETUP and select auto-ranging mode.
Note: Auto-ranging is automatically restored if the range is changed, if
the meter is turned off and back on again or if the calibration
mode is entered.
