Page 6: Preparation
3. Preparation Inserting the Batteries Four AAA batteries are included with your meter. Use a Phillips screwdriver to remove the two screws holding the battery cover. See Figure below. Lift meter stand to expose battery cover. Remove battery cover. Insert batteries. Follow the diagram inside the cover for correct polarity. Replace the battery cover into its original position using the two screws removed earlier. -
Page 7: Connecting The Probe And Temperature Sensor
Connecting the Probe and Temperature Sensor NOTE: Keep connector dry and clean. Do not touch connector with soiled hands. Slide the BNC connector of the probe over the BNC connector socket on the meter. Make sure the slots of the connector are in line with the posts of the socket. -
Page 8: Attaching The Probe Holder To The Meter
Attaching the Probe Holder to the Meter Place the probe holder with the flange facing the slot on the meter. See Figure Gently slide the flange of the holder into the slot on the meter. Make sure the holder is secured properly into the slot. You can attach the probe holder in different positions. -
Page 9: Connecting The Ac Adapter
Connecting the AC Adapter The AC adapter is not included with your meter; order separately on page 24. Insert the AC jack as shown in figure below. Switch off the meter before plugging the adapter into the power source. This safety precaution protects the software in your meter. Press the ON/OFF button to switch meter on. -
Page 10: Calibration
4. Conductivity/TDS Calibration Preparing for calibration Selecting a calibration standard For best results, select a conductivity or TDS standard near the sample value you are measuring. Alternatively, use a calibration solution value that is approximately 2/3 the full scale (F.S.) value of the measurement range you plan to use. For example, in the 0 to 1999 µS range, use a 1413 µS solution for calibration. -
Page 11: Calibrating For Conductivity
Conductivity calibration Select the conductivity standard for calibration. Select a standard with a value closest to the expected value of measurements in the sample. Pour 3 cm of the standard into two separate clean containers. Turn the meter on. All the LCD segments display for a few seconds. The LCD then switches into the conductivity measurement mode. -
Page 12: Calibrating For Tds
TDS calibration Option 1: TDS calibration using TDS standards Select the TDS standard for calibration. Our OAKTON calibration solutions have TDS values on the labels. For conversion factors other than those listed, see Addenda 1 and 2, pages 25-26. Pour 3 cm of the standard into two separate clean containers. - Page 13 Option 2: TDS calibration using conversion factors TDS values are related to conductivity. You can calibrate the meter using conductivity standards as described above and then program the meter with a given conversion factor. Perform the conductivity calibration procedure on page 11. Select the correct Conductivity-to-TDS conversion factor.

Page 14: Temperature Calibration
5. Temperature Calibration The built-in temperature sensor included in the probe is factory calibrated. Over time, the temperature sensor response may vary. If you suspect temperature errors, calibrate your sensor using the following one-point calibration procedure. If you purchase a replacement probe, you must complete a two-point temperature calibration. -
Page 15: Measurement
6. Measurement Range Selection The 35607-series meters will default to the auto-ranging mode. Auto-ranging deter- mines and selects the range that gives you the greatest resolution and accuracy. Alternatively, you can manually select one of four ranges using the range key. For example, if you prefer the meter to display a reading as 0.50 mS rather than 500 µS, while in measurement mode, select the 0 to 19.99 mS range using the range key. -

Measurement with Manual Temperature Compensation Leave the temperature sensor phono jack unplugged from the meter. Attach the probe with only the BNC connector. Switch on the meter. The MEAS annunciator and the AUTO (Auto-ranging) annunciator display on the top center of the LCD. -
Page 17: Hold
7. HOLD function This feature lets you freeze the value of the Conductivity or TDS and temperature readings for a delayed observation. HOLD can be used any time when in MEAS mode. HOLD To hold a measurement, press the HOLD key while in measurement mode. -
Page 18: Probe Care And Maintenance
8. Probe Care and Maintenance Keep the conductivity probe clean. Rinse the probe twice, and gently swirl it while you take readings. For best accuracy, soak a dry probe for at least 5 to 10 minutes or longer before calibration or taking readings. Wash the probe with deionized or tap water before storing it. -
Page 19: Probe Replacement
9. Probe Replacement Your meter and probe have been factory calibrated to each other for maximum accuracy. If you notice a reduction in accuracy after replacing your probe, perform a zero calibration and two-point temperature calibration. Zero calibration NOTE: the probe must be dry and in air for zero adjustment. Connect the BNC and phone jacks of the probe to the conductivity meter. -
Page 20: Two Point Temperature Calibration
Two point temperature calibration After zero calibration, the meter proceeds to program 6.0, for temperature calibration of the probe. The temperature in °C shows in the primary display and “r6.0” shows in the secondary display. See figure Press CAL/MEAS until the meter automatically switches off to skip this section of the calibration. -
