Operating Instructions

Power ON/OFF
Turn the meter on or off by pressing the Power button.

Measurement Modes
The R3530 offers 3 measurement modes:

• Conductivity
• Total Dissolved Solids
• Salinity (Salt)
  When the meter is on, press the MODE button to toggle between “COND” for conductivity measurements, “TDS” for total dissolved solids measurements & “SALT” for salinity measurements.

Selecting the Temperature Unit of Measure
When the meter is first powered ON, the default scale setting is set to Celsius (°C).
Press and hold the MODE button to toggle between °C and °F.
Note: The meter will automatically save the selected unit of measure as the new default when powered off.

Taking Measurements
Submerge the electrode in the solution to be tested while stirring gently.
Wait for the measurements to stabilize. The applicable measurement value automatically compensated for temperature is shown at the top of the LCD Display whereas the secondary value below indicates the temperature of the sample.
Note: When the applicable measurement value is over the measurement range, the LCD display will indicate “—“.
Note 2: The meter will auto-range to the proper range (μS/cm or mS/cm, ppm or ppt) and then display the reading.

Data Hold

1. Press the hold button to freeze the current reading on the display.
2. While in this mode “Hold” will appear on the LCD display.
3. Press the hold button again to resume normal operation.
   continued…

MAX/MIN Function

1. Press and hold the Max/Min button to access the Maximum/Minimum modes.
2. The MAX and MIN indicators will blink continuously. The Maximum & Minimum values will automatically update in the Max/Min memory while the current applicable measurements are displayed.
3. To view the Max/Min measurements during this mode press the Max/Min button at any time to toggle through stored measurements.
4. To exit Max/Min mode and resume normal operation, press and hold the Max/Min button for approx. 3 seconds.

Auto Power Off
To preserve battery life, the meter is programmed to turn off after approximately 10 minutes of inactivity.
Calibration
Meter accuracy should be performed on a periodic basis. If calibration is required, a conductivity standard solution is required. The meter can be calibrated in any of the three ranges. Standard solutions of 84µS/cm, 1413µS/cm (included) or 12.88mS/cm (12,880µS/cm) are used for the automatic calibration recognition procedure.
Note: Calibration is always done in conductivity mode. Since salinity and TDS values are calculated from conductivity values, this procedure also calibrates the salinity and TDS ranges.

1. Fill a sample cup with the conductivity standard solution.
2. Turn the meter ON and insert the electrode into the solution so that the tip of the electrode is fully immersed and stir at a moderate, uniform rate. Tap or move the electrode in the sample to dislodge any air bubbles.
3. Press and hold the CAL button (approximately 2 seconds) until “CAL” appears in the lower display. The main display will start flashing.
4. The meter will automatically recognize and calibrate to the conductivity standard solution.
5. The display will indicate “SA” followed by “End” and resume normal operation when calibration is complete.
   Note: “SA” will not appear if the meter fails calibration.

Battery Replacement

When the low battery icon appears on the LCD, the batteries must be replaced.

1. Loosen both screws using the included Allen Key from the battery compartment cap.
2. Remove the battery compartment cap.
3. Replace the four (4) “AAA” batteries.
4. Secure the battery compartment cap back using the two (2) screws.

Electrode Replacement

1. To remove the electrode, unscrew (Counter-Clockwise) and completely remove the electrode collar.
2. Gently pull the electrode module to disconnect it from the meter rock the electrode from side to side, pulling it downwards, until it disconnects from the meter.
3. Carefully plug the replacement electrode into the meter socket, ensuring proper connection.
4. Tighten the electrode collar back into place.
