4. To measure the conductivity of a solution, power on the meter and press the M
button until the display shows the term "Cd". Plug the conductivity/TDS/salt probe into
its dedicated socket (callout 1-15 of Fig. 1) on the top of the meter.
Following are the default states for the WK2017SD in conductivity measurement mode:
• The display shows "Cd"
• Temperature unit of ºC
• Temperature compensation factor of 2% per °C
• Autoranging on
• Auto power off
• Sampling time of 2 seconds
To change any of these parameters, use the specific procedure for it detailed in the Setup
section. To exit autoranging mode and manually enter a full-scale measurement range,
press the M button (which has the word "RANGE" stenciled below it) repeatedly until the
desired range appears. The options are 200 uS, 2 mS, 20 mS and 200 mS. If the display
shows a reading other than zero before the probe is inserted in the solution to be tested,
press the L button and hold it for at least 10 seconds until the display reads zero (this
zeroing function only works in the 200 uS full-scale range and only when the original non-
zero value that appears is less than 2 uS).
To make the conductivity measurement, hold the conductivity probe by its handle and
immerse it in the solution under test. Gently shake the head of the probe to help any air
bubbles escape and to ensure an accurate reading. The display will show both the
conductivity of the solution in uS or mS and its temperature.
5. To measure the TDS content of a solution, power on the meter and press the M button
until the display shows the term "Cd", indicating operation in conductivity measurement
mode. Then press the press the M or L button until the term "tdS" appears. Next, press
the REC/ENTER button to store the setting as the temporary default. Finally, plug a
conductivity/TDS/salt probe into its dedicated socket (callout 1-15 of Fig. 1) on the top of
the meter.
To make the TDS measurement, hold the conductivity probe by its handle and immerse it
in the solution under test. Gently shake the head of the probe to help any air bubbles
escape and to ensure an accurate reading. The display will show both the TDS of the
solution in uS or mS and its temperature.
6. To measure the salt content of a solution, power on the meter and press the M button
until the display shows the term "Cd", again indicating operation in conductivity
measurement mode. Then press the M or L button until the term "SALt" appears.
Next, press the REC/ENTER button to store the setting as the temporary default.
To make the salt content measurement, hold the conductivity probe by its handle and
immerse it in the solution under test. Gently shake the head of the probe to help any air
bubbles escape and to ensure an accurate reading. The display will show the salt content
of the solution as a % by weight value.
