Instruction Manual PC 510

1 INTRODUCTION

Thank you for selecting the PC 510 pH and Conductivity bench meter. This step-by-step instruction manual gives you a detailed description on the use and operation of features on the meter. This PC 510 pH and Conductivity bench meter is designed to be user-friendly while providing unprecedented levels of accuracy, repeatability and reliability.

The PC 510 is an advanced microprocessor-based (ASIC - Application Specific Integrated Circuit) ideal for routine measurement that best meets discerning user’s individual needs. This multi-parameter meter reads pH, mV, Conductivity, Total Dissolved Solids (TDS) and temperature (°C or °F). It has splash-proof keypad, simultaneous pH/mV/Conductivity/TDS and temperature display on a large angled custom LCD. This instruction manual is illustrated with useful hints and diagrams that show which specific key-presses to access for each function.

2 METER INFORMATION

The PC 510 meter is packaged in a corrugated box that is made of environment-friendly materials and can be re-cycled.

2.1 Meter parts

The instrument is designed to give an aesthetic look as well as ergonomic functionality. A large custom dual LCD is provided at an angle for optimum viewing. A splash-proof keypad with audible tactile response gives you a good feel of the instrument. A slide-out instruction card offers a handy reference. Listed below are the major components of the meter.

2.2 Customised LCD

The PC 510 bench meter is characterised by large dual custom LCD (Liquid Crystal Display). The display has also mode annunciators for pH, temperature, mV, conductivity and TDS readings. The secondary (lower) display shows the temperature readings simultaneously with the primary (upper) display of measured mode. Special annunciators such as graphical symbols, error messages, measurement units and modes of operation are arranged around the primary and secondary displays to give a comprehensive display. The integration of graphics and error messages into the LCD provides you a higher level of user-friendliness and easy readability.

2.3 Slide-out card

A plastic slide-out card is provided at the bottom of the PC 510 bench meter. The function of this card is to provide a quick guide to the functions of the individual keys as well as to provide a useful troubleshooting reference.

2.4 Rear instrument panel

The PC 510 bench meter provides three connectors at the rear of the meters. These connectors are labeled CON/TEMP, pH and DC.

2.5 AC/DC adapter

The AC/DC adapter converts the power mains voltage 120/220 VAC to low DC voltage for the PC 510 bench meter operation. Two basic models of adapters are available depending upon power supply specification of each country.

Description Order Code Voltage

AC Adapter 120 V EC-120-ADA / 35615-07 110-120 V, 50-60 Hz AC Adapter 220 V EC-220-ADA / 35615-08 220-240 V, 50-60 Hz

2.6 Electrodes

Your meter includes two probes:

• pH electrode with BNC connector

• conductivity probe with built-in temperature sensor with a notched 6-pin connector

The temperature sensor built into the conductivity probe will also compensate for pH readings as long as both probes are in your solution at the same time.

If you want to use a “3-in-1” pH probe with a built-in temperature sensor, or if you want to use a separate temperature probe, you will need to disconnect the conductivity probe to allow for connection of the separate temperature sensor.

2.7 Electrode holder

The integral electrode holder serves as a handy holder for mounting the pH and conductivity/temperature probes during measurement or when idle.

The bench meter’s base plate has a side metal bar to which you can attach an integral swivel electrode holder. You can mount the electrode holder on either right or left side of the meter.

5 CALIBRATION

5.1 Important information on meter calibration

When you calibrate 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.

• Conductivity

: if you previously calibrated your meter at 1413 µS in the 0 to 1999 µS range and

you recalibrate at 1500 µS (which is also in the 0 to 1999µS range), the meter will replace the old calibration data (1413 µS) in that range. The meter will retain all calibration data in other ranges.

• TDS

: If you previously calibrated your conduc tivity meter at 300 ppm in the 0 to 999 ppm range

and you re-calibrate at 500 ppm (which is also in the 0 to 999 ppm), the meter will replace the old calibration data (300 ppm) in that range. The meter will retain all calibration data in other ranges.

To view current calibration points:

• pH

• Conductivity & TDS

: Program P1.0 in the SETUP section 8.2 page 38.

: Program P5.0 in the SETUP section, page 32.

To completely recalibrate your meter, or when you use a replacement probe, it is best to clear old calibration data by resetting the meter.

To reset the meter to its factory defaults:

• pH

• Conductivity & TDS

: Program P4.0 in the SETUP section, page 32.

: Program P9.0 in the SETUP section, page 38.

: Resetting the meter will set meter to factory defaults. Conductivity and pH must be reset

NOTE

separately.

For directions on how to calibrate your meter:

• See section 5.3 on page 7 for pH calibration

• See section 5.4 on pages 9 for conductivity calibration

• See section 5.5 on page 11 for TDS calibration

5.2 Preparing the meter for calibration

Before starting calibration, make sure you are in the correct measurement mode. When you switch on the meter, the meter starts up in the measurement mode you shut it off in. For example, if you shut the meter off in pH measurement mode, the meter will be in the pH measurement mode when you switch the meter on.

Do not re-use calibration solutions after calibration. Contaminants in the solution can affect the calibration, and eventually the accuracy of the measurements. See section 13 on “Accessories” on page 44 for information on our high quality calibration solutions.

Instruction Manual PC 510

5.3 pH calibration

NOTE: We recommend that you perform at least a 2-point calibration using standard buffers that bracket (one above and one below) the expected sample range.

5.3.1 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. Select from the following buffer options:

• USA: pH 1.68, 4.01, 7.00, 10.01 and 12.45

• NIST: pH 1.68, 4.01, 6.86, 9.18 and 12.45

The meter automatically recognises and calibrates to these standard buffer values, which makes pH calibration faster and easier.

NOTE:

Selection of USA or NIST buffer standards must be done prior to calibration. Refer to Section

8.4 on P3.3 on page 29.

5.3.2 Before starting

Be sure to remove the protective electrode storage bottle or rubber cap of the probe before calibration or measurement. If the electrode has been stored dry, hydrate the probe in tap water for 10 minutes before calibrating or taking readings to saturate the pH electrode surface and minimise drift.

Wash your probe in de-ionised water after use, and store in electrode storage solution. If storage solution is not available, use pH 4.01 or

7.00 buffer for short term storage. DO NOT store electrode in distilled

or de-ionised water.

5.3.3 To calibrate pH

1. If necessary, press the MODE key to select pH mode. The pH indicator appears in the upper right hand corner of the display.

2. Rinse the probe thoroughly with de-ionised water or rinse solution. Do not wipe the probe as this causes a build-up of electrostatic charge on the glass surface.

3. Dip the probe into the standard calibration buffer. The end of the probe must be completely immersed into the sample. Stir the probe gently to create a homogeneous sample.

NOTE

: The temperature element is in the conductivity cell. For

temperature compensated readings, dip the conductivity cell or ATC probe into the calibration buffer as well.

4. Press CAL/MEAS to enter pH c alibration mode. The CAL indicator will be shown. The primary display will show the measured reading while the smaller secondary display will indicate the pH standard buffer solution.

5. Wait for the measured pH value to stabilise. If the READY indicator has been activated through the Setup, the READY appears when the reading is stable.

5.4 Conductivity/TDS calibration

The PC 510 has 5 measuring ranges. You can calibrate 1 point each of the measuring ranges (up to 5 points). If you are measuring values in more than 1 range, make sure to calibrate each of the ranges you are measuring. All new calibration data will over-ride existing stored calibration data for each measuring range you calibrate.

• If you are measuring in ranges near to or greater than 20 mS (10 ppt), or near to or lower than 100 µS (50 ppm), calibrate the meter at least once a week to get specified ±1% Full Scale accuracy.

• If you are measuring in the mid-ranges and you washed the probe in de-ionised water and stored it dry, calibrate the meter at least once a month.

• If you take measurements at extreme temperatures, calibrate the meter at least once a week.

5.4.1 Preparing for conductivity/TDS calibration

For best results, select a standard value close to the sample value you are measuring. Alternatively, use a calibration solution value that is approximately 2/3 the Full-Scale value of the measurement range you plan to use. For example, in the 0 to 1999 µS conductivity range, a 1413 µS solution is a good solution for calibration.

See the table below for recommended calibration solution ranges.

Calibration Solution Ranges

Temperature Coefficient: These meters are factory set to a temperature coefficient of 2.1 % per °C.

For most applications this will provide good results. See Program P8.1 on page 37 to set the temperature coefficient to different value. See Addendum 2, “Calculating Temperature Coefficients” to determine the appropriate temperature coefficient for your solution.

Normalisation Temperature: The factory default value for normalisation temperature is 25 °C. If you need to normalise to a value other than 25 °C, see Program P8.2 on page 38.

Do not reuse calibration solutions after calibration. Contaminants in the solution can affect the calibration, and eventually the accuracy of the measurements. Use fresh calibration solution each time you calibrate your meter.

All new calibration data will over-ride existing stored calibration data for each measuring range calibrated.

Instruction Manual PC 510

Calibrating for Conductivity:

1. If necessary, press the MODE key to select conductivity mode.

2. Rinse the probe thoroughly with de-ionised water or a rinse solution, then rinse with a small amount of calibration standard.

3. If necessary, ensure that the probe’s yellow probe guard is attached. Dip the probe into the calibration standard. Immerse the probe tip beyond the upper steel band. Stir the probe gently to create a homogeneous sample.

4. Wait for the measured conductivity value to stabilise. If the READY indicator has been activated (SETUP program P7.1 – see page

31), the READY annunciator lights when the reading is stable.

5. Press CAL/MEAS to enter conductivity or TDS calibration mode. The CAL indicator will appear in the upper right corner of the display.

6. Press the  or  key to change the value on the primary display to match the value of the calibration standard.

7. Press ENTER to confirm calibration value. The meter returns to the MEAS (measurement) mode.

8. Repeat steps 1 to 7 for other measuring ranges.

NOTES

: When entering calibration mode, the meter will display the

factory default value. If the meter was previously calibrated, the display may “jump” to the factory default / uncalibrated value when switching from measurement to calibration mode.

To exit from Conductivity calibration mode confirming calibration, DO NOT press the ENTER key in step 7. Press CAL/MEAS instead.

This will retain the meter’s old calibration data in the measuring range of the calibration.

5.6 Calibration with Conductivity Standard and TDS factor

The concentration of salts dissolved in solution increases the conductivity of that solution. This relationship varies from salt to salt and is roughly linear over a given range for a given salt.

The TDS conversion factor is the number used by the meter to convert from conductivity to TDS. Instead of calibrating for TDS directly (described above), you can calibrate the PC 510 bench meter

by:

1. Calibrating to conductivity standards (as described above) and then

2. Entering the appropriate TDS conversion factor into the meter.

To determine the conductivity to TDS conversion factor for your solution:

5.7 Temperature Calibration

The conductivity electrode (EC-CONSEN91W / 35608-50) supplied has a built-in temperature sensor. Alternatively, a separate temperature sensing element can be used (such as temperature probe EC-WPPHTEM-01W / 35618-05), or a “3-in-1” pH/Temperature combination electrode with ATC connection.

The conductivity probe is factory calibrated. Temperature calibration is recommended only if you suspect temperature errors may have occurred over a long period of time, or if you have a replacement probe.

Temperature calibration is accessible during pH, conductivity or TDS calibration.

Temperature Calibration

1. Make sure the conductivity electrode, or temperature probe, or “3-in-1” electrode is attached to the 6-pin connector.

2. Switch the meter on.

3. Press the CAL/MEAS key to enter calibration mode (either from pH or conductivity mode). The CAL indicator will appear above the primary display.

4. While in pH (or conductivity or TDS) calibration mode, press the MODE key to enter temperature calibration mode. The primary display shows the last set temperature value and the secondary display shows the temperature reading with zero offset.

5. Dip the ATC probe into a solution of known temperature (i.e. a temperature bath). Allow time for the temperature probe to stabilise.

4. Dip the probe into the sample. Since the conductivity cell contains the temperature sensor, make sure it is also immersed in your solution.

When dipping the probe into the sample, the sensor or the glass bulb of the electrode must be completely immersed into the sample. Stir the probe gently in the sample to create a homogeneous sample.

5. Allow time for the reading to stabilise. Note the reading on the display. If the READY indicator is selected on, it will appear when the reading is stable. See below for more information.

Taking measurements with READY indicator selected on

If the READY indicator has been activated, the READY annunciator lights when the reading is stable *.

Switch the READY indicator on or off in SETUP program P3.1. See page 28 for directions. * The READY indicator appears and the reading holds until the measured value exceeds the tolerance

(±0.02 pH; +0.8 mV < 400; ±1.2 mV > 400). Then READY annunciator turns off.

9 PROBE CARE AND MAINTENANCE

9.1 pH Electrode care

Since your pH electrode is susceptible to dirt and cont amination, clean as necessary depending on the extent and condition of use.

: For specialty electrode care, consult your electrode instruction manual .

NOTE

pH electrode storage

For best results, keep the pH bulb hydrated. Use the protective electrode storage bottle or rubber cap filled with electrode storage solution to store your electrode. Alternatively, you can store in a pH 4 buffer with 1/100 part of saturated KCl. Other pH buffers are OK for short term storage, but NEVER use distilled water for storage.

After measuring

1. Rinse the pH electrode and reference junction in de-ionised water.

2. Store the electrode as recommended above in “pH electrode storage solution”, or as recommended by the manufacturer.

3. Prior to next use, rinse the liquid junction with de-ionised water and tap dry – never wipe electrode.

NOTE

: If this does not restore electrode to normal response, see “Reactivating the pH electrode”

section below.

pH electrode cleaning

• Salt deposits: Dissolved the deposits by immersing the electrode in tap water for ten to fifteen minutes. Then thoroughly rinse with distilled water.

• Oil/Grease film: Wash electrode pH bulb gently in some detergent and water. Rinse electrode tip with distilled water or use a general purpose electrode cleaner (see ordering informatio n).

• Clogged reference junction: Heat a diluted KCl solution to 60 to 80 °C. Place the sensing part of the electrode into the heated solution for about 10 minutes. Allow the electrode to cool in some unheated KCl solution.

• Protein deposits: Prepare a 1% pepsin solution in 0.1 M of HCl. Set the electrode in the solution for five to ten minutes. Rinse the electrode with distilled water.

Reactivating the pH electrode

If stored and cleaned properly, your pH electrode should be ready for immediate use. However, a dehydrated bulb may cause sluggish response. To rehydrate the bulb, immerse the electrode in a pH 4 buffer solution for 10 to 30 minutes. If this fails, the electrode requires activation. Never touch or rub glass bulb. Contact builds up an electro-static charge.

39

Instruction Manual PC 510

pH electrode activation (for glass body electrodes only) WARNING

: Only qualified persons with proficient with the safe handling of dangerous chemicals

should perform the procedure below. Provide proper containers, fume hoods, ventilation and waste disposal. Safety goggles and protective clothing must be worn while performing this procedure. If possible, replace with another electrode instead of performing this re-activation procedure.

1. Dip or stir the pH electrode in alcohol for 5 minutes.

2. Leave the electrode in tap water for 15 minutes.

3. Dip and stir the electrode in concentrate acid (such as HCl or H2SO4) for 5 minutes.

4. Repeat Step 2.

5. Dip and stir in strong base (NaOH) for 5 minutes.

6. Leave for 15 minutes in tap water.

7. Now test with standard calibration buffer solutions to see if the electrode yields acceptable results. You may repeat step 3 through 6 up to three times for better response. If the response does not improve, then your electrode is no longer functioning. Replace with a new electrode – call your distributor for information.

9.2 Conductivity electrode

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. Rinse the probe with de-ionised or tap water before storing. Never scratch the bands with a hard substance. Do not strike the probe against any hard surface.

Do not immerse the probe in oily solutions. Clean the electrode thoroughly by stirring it in a mild detergent bath or isopropyl alcohol. Wipe the probe with a soft tissue paper. Rinse thoroughly in tap water and then in de-ionised water. Re-calibrate the meter after cleaning the probe.

The conductivity probe included with your meter features a removable probe guard for easy cleaning.

To remove probe guard:

1. Grip yellow probe guard and twist clockwise. The locking notch will release.

2. Slide probe guard off end of probe.

15 ADDENDUM 2: CALCULATING TDS CONVERSION FACTORS

You can calibrate your meter using TDS calibration standard solutions. The calibration standard only needs to give the TDS value at a standard temperature such as 25 °C. To determine the conductivityto-TDS conversion factor use the following formula:

Factor = Actual TDS ÷ Actual Conductivity @ 25 °C

Definitions

:

• Actual TDS: Value from the solution bottle label or as a standard you make using high purity water and precisely weighed salts.

• Actual Conductivity: Value measured using a properly calibrated Conductivity/Temperature meter.

Both the Actual TDS and the Actual Conductivity values must be in the same magnitude of units. For example, if the TDS value is in ppm the conductivity value must be in µS; if the TDS value is in ppt the conductivity value must me in mS.

Check your factor by multiplying the conductivity reading by the factor in the above formula. The result should be in TDS value.
