6. Use the NORTEC 600 instrument and probe to measure the conductivity of the
test material and the thickness of the nonconductive paint layer on the test
material.
Conductivity measurement screen
After a successful calibration, the conductivity measurement screen is displayed. This
screen displays the conductivity and coating thickness values. A bar graph shows the
current measurement value (between the minimum and maximum values), and
arrows indicate the minimum and maximum alarm thresholds (if enabled).
Conductivity measurements continue until the conductivity probe is disconnected,
which closes the measurement window. If the instrument senses that there is no
longer a conductive surface under the conductivity probe, the conductivity and
coating thickness readings on the screen are refreshed (renewed).
Conductivity mode with impedance plane
While in conductivity/coating thickness mode, the NORTEC 600 can display an
impedance plane. To activate this view, press and hold the MAIN FILTER menu key
( ), and then press the GAIN key ( ). However, the functionalities of this
special function have yet to be tested, so it should only be used for research purposes
and none of the parameters should be changed.
To save measurements
Save your conductivity and coating thickness measurements at any time by
pressing the REF SAVE key ( ). Saved measurements can be reviewed later in
the datalogger or in the memory screen.
To set alarms for conductivity and coating thickness
High and low threshold alarm settings are available for conductivity and coating
thickness measurements. Alarms can be set as positive or negative and with or
without an audible alarm sound.
