1. Resistivity Setup
The resistivity setup screen presents many options to control the operating
parameters, which can be controlled and set from the resistivity setup screen. The
settings are displayed in 2 pages. Press
NEXT-P (F2) and PREV-P (F1) to navigate
through these pages.

This page allows you to set operating parameters for resistivity measurement mode:
Parameter Description Factory
Default
Pure water
Coeff.
Pure water coefficient will be calculated and applied automatically
for ultra pure water measurement if enabled.
ENABLE
Lnr Temp
Coefficient
Specify temperature coefficient to measure temperature
corrected conductivity
2.100
Normalization
Temp Select a default temperature that the meter will use along with the
temperature coefficient to calculate a temperature corrected
conductivity measurement. 25
Cell Constant
Select the appropriate cell constant of the conductivity cell.
Available cell constants: 0.1 to 10
1.000
Calibration
due Specify number of days for the Conductivity calibration alarm. The
meter shows CAL DUE indicator after calibration date.
Available range : 0 to 30 (if enabled)
DISABLE
Calibration
points Single - In single point calibration one calibrated conductivity
value can be used for the entire 5 conductivity ranges.
Multi - In multi point calibration, you can calibrate one point in
each of the measuring ranges (up to 5 points.)
Single
TDS factor
The TDS conversion factor is the number used by the meter to
convert from conductivity to TDS. The TDS conversion factor
automatically adjusts the reading. The TDS conversion factor can
be set from 0.40 to 1.00
0.500
