Page 3: Starting Up
1. Starting up Thank you for purchasing an OAKTON ® pH/CON 510 benchtop meter. This multiparameter meter reads pH, mV, Conductivity, Total Dissolved Solids (TDS), and temperature (°C or °F). It is microprocessor controlled, user-friendly and reliable. Keypad See Figure 1. -
Page 4: Display
Display See Figure 2. The OAKTON ® pH/CON 510 meter features a large dual display that shows the measured parameter in the primary display, plus temperature in °C or °F in the secondary display. It also features mode annunciators that describe the meter’s functions. -
Page 5: Electrode Holder Arm
Electrode Holder Arm Bottom of meter The electrode holder is included in the same box as the meter. Shipping position To attach the electrode holder to the meter: The electrode holder base attached to the bottom of the meter comes in the ship- ping position. -
Page 6: Electrode Holder Arm
To install the electrode arm, turn meter back to the upright position. See Figure 6. Line up the hole on the base of the electrode holder arm with the peg on the electrode holder base. Slide the hole securely onto the electrode holder base. See Figure 7. -
Page 7: Probe Connections
Probe connections See Figure 9 . Your meter includes two probes: CON/TEMP • pH electrode with BNC connector • conductivity/TDS/temperature probe with a notched Figure 9 6-pin connector The temperature sensing element built into the conductiv- ity/TDS probe will also compensate for pH readings as long as both probes are in your solution at the same time. -
Page 8: Calibration
2. Calibration Important Information on Meter Calibration When you recalibrate your meter, old calibration points are replaced on a “point by point” basis in pH, and on a “range by range” basis in conductivity or TDS. For example: • pH: if you previously calibrated your meter at pH 4.01, 7.00, and 10.01, and you recalibrate at pH 7.00, the meter retains the old calibration data at pH 4.01 and pH 10.01. -
Page 9: Ph Calibration
pH calibration We recommend that you perform at least a 2-point calibra- tion using standard buffers that bracket (one above and one below) the expected sample range. Preparing for pH calibration This meter is capable of up to 5-point pH calibration to ensure accuracy across the entire pH range of the meter. -
Page 10: Ph Calibration
To calibrate pH: If necessary, press the MODE key to select pH measurement mode. The pH indicator appears in the upper right hand corner of the display. MEAS See Figure 10 READY Rinse the pH electrode thoroughly with de-ionized water or a rinse solution. -
Page 11: Conductivity/Tds Calibration
Conductivity/TDS calibration This meter is capable of up to 5-point conductivity or TDS calibration at one point per range: Conductivity: TDS: 0.00-19.99 µS 0.00-9.99 ppm 0.0-199.9 µS 10.0-99.9 ppm 0-1999 µS 100-999 ppm 0.00-19.99 mS 1.00-9.99 ppt 0.0-199.9 mS 10.0-199.9 ppt If you are measuring values in more than one range, make sure to calibrate each of the ranges you are measuring. -
Page 12: Conductivity/Tds Calibration
To calibrate conductivity or TDS: If necessary, press the MODE key to select conductivity or MEAS TDS mode. READY See Figure 13 Rinse the probe thoroughly with de-ionized water or a rinse solution, then rinse with a small amount of calibration standard. -
Page 13: Temperature Calibration
Temperature calibration The temperature sensor (located in the conductivity/TDS cell) is factory calibrated. Calibrate your sensor only if you suspect sensor drift that may have occurred over a long period of time or if you have a replacement probe. Temperature calibration Make sure the conductivity/TDS cell (or alternative tem- perature element) is attached to the 6-pin connector. -
Page 14: Measurement
