Conductivity, TDS, Salinity, & Resistivity Setup
Use Setup mode to customize Conductivity, TDS, Salinity, & Resistivity
parameters.
Press
SETUP
from the measurement screen and then press
ENTER
when
Conductivity
,
TDS
,
Salinity
, or
Resistivity
is selected.
STD METHOD (Conductivity Mode Only)
Choose automatic or manual standardization for conductivity, and manual
standardization for TDS, Salinity, and Resistivity. This option allows you to select
AUTO
(automatic) or
MANUAL
conductivity calibration.
In the automatic calibration mode, the meter will automatically select one of (4)
conductivity calibration standard values depending on the range and
normalization temperature being used (see table below).

If you will only use one or more of the (4) calibration standards listed here,
automatic calibration is recommended. Otherwise, manual calibration should
be selected.
The factory default is automatic conductivity calibration. Note that automatic
calibration is not available for conductivity range 1.
STD POINTS
Use
SINGLE
for Single-Point Calibration (SPC) to apply a single calibration value
across all ranges.
Use
MULTI
for Multi-Point Calibration (MPC) to calibrate each range individually.
This will restrict an individual calibration so that it is applied to one range only.
When using multi-point calibration, perform a calibration in each range that you
expect to use for best results.
The factory default is SPC. SPC or MPC will be shown with the calibration details
in measurement mode.
