1. Click or tap the sensor meter to view sensor options.
2. Select Calibrate and follow the applicable prompts on the Calibrate Sensor
screen.
In order to calibrate Go Direct Platinum-Cell Conductivity, or to confirm that a
saved calibration is accurate, you should have a supply of conductivity standard
solutions that cover the range of the conductivity values you will be measuring.
For more information about conductivity standard solutions, including recipes
for preparation, see
Once you have calibrated a Go Direct sensor, the calibration is automatically
stored to the sensor and will be used each time you connect to your device. You
can always choose to restore factory defaults if you feel the custom calibration
is invalid.
To restore factory defaults in Graphical Analysis, complete the following steps.
1. Click or tap the live readouts meter and choose Calibrate.
2. Click or tap Reset Calibration.
3. A window will appear warning you that you are about to reset the
calibration. Choose Reset Calibration.

Connected and charging
Blue and Green LED are solid when sensor is
connected to Graphical Analysis via USB and
unit is charging. (Green LED is obscured by the
blue one.)
Connected, fully charged
Green LED is solid when sensor is connected to
Graphical Analysis via USB and the unit is fully
charged.
Charging via USB,
connected via Bluetooth
Blue LED is solid and green LED is flashing, but
the green flashing LED looks white because it is
overwhelmed by the blue.
Identifying the Sensor
When two or more sensors are connected, the sensors can be identified by
tapping or clicking Identify in Sensor Information.
Using the Product
1. Thoroughly rinse the lower section of the probe using distilled or deionized
water.
2. Connect the sensor following the steps in the Getting Started section of this
user manual.
Note:
Given the nature of the platinum-cell electrode, a one-
point calibration is strongly recommended prior to use.
3. When you are finished making measurements, rinse the electrode with
distilled water. Store dry.
Note:
Go Direct Platinum-Cell Conductivity has three sensor channels. By
default, the probe measures temperature compensated conductivity. The other
two channels are temperature and non-temperature compensated conductivity.
Channels

Calibrating the Sensor
For the most accurate measurements with this sensor, we recommend a one-point
calibration. It is a simple process that takes only a few minutes. For additional
calibration information, see
To calibrate the sensor in Graphical Analysis, complete the following steps.
