PREPARATION
Conductivity Electrode Information
The CON510 bench meter is supplied with a Conductivity/TDS electrode (with a sturdy locking 6-pin
connector). This Conductivity/TDS electrode (Code No: ECCONSEN91W/ 35608-50) comes with
Stainless Steel rings, cell constant of K = 1.0, and a built-in temperature sensor for Automatic
Temperature Compensation (ATC). Its specially designed Ultem-body housing has good chemicalresistant properties. It provides fast temperature response and reduces air bubble entrapment,
which makes it easy to obtain accurate, stable readings.
The probe materials used which have good chemical durability include:
1. Polyetherimide (Ultem) – protective probe guard
2. Polybutylterphalate (Valox) – sensor housing
3. Stainless Steel (SS 304) – 2 steel bands
Proper use of probe is essential to ensure that the optimum measurement is taken in a short time.
The removable protective plastic probe guard is meant for simple periodic maintenance and it must
be kept in tact during measurement and calibration.
Always immerse the probe beyond upper steel band.
NOTE: DO NOT remove the protective probe guard during measurement and calibration as it may
affect your readings.
NOTE: We recommend that you do not submerge the probe above the protective probe guard. You
can submerge the cable for brief periods of time, but not continuously.
See Section 8 for “Probe Care and Maintenance” information.

CALIBRATION
4.1
Important Information on Meter Calibration
The CON 510 bench meter allows you to perform automatic calibration (only for Conductivity mode) or manual calibration
(applicable to both Conductivity/TDS mode). The meter can calibrate either single point or multi-point up to 5 calibration
points (manual mode) with a maximum of 1 point in each measurement range. Use single-point automatic calibration
when calibrating using Conductivity standard calibration solutions (as mentioned in Section 4.6) as it suffices.
When calibrating using uncommon or non-standard Conductivity/TDS calibration solutions which are freshly prepared,
use the manual calibration option as it allows you to manually set to the desired value to match the standards being
used. However if you are measuring sample values in more than one range, it is recommended to calibrate each of the
ranges which you are measuring to ensure best meter accuracy.
•
If you are measuring in ranges near to or greater than 20 mS (10 ppt if TDS factor is set to 0.5), 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-ionized 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.
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 2000 µS/cm conductivity range, a 1413 µS/cm solution is a good solution for calibration.
The following table lists all the corresponding conductivity and TDS ranges. You should calibrate each range using a
suitable standards solution that falls between the values in the “recommended calibration solution range” column.

Range
Indicator
When you recalibrate your meter, old calibration values are replaced on that specific measurement range. For example,
if you previously calibrated the meter at 1413 µS/cm in the 0 - 2000 µS/cm range and you recalibrate at 1500 µS/cm (in
the same range of 0 - 2000 µS/cm), the meter will replace old calibration data (1413 µS/cm) in that range if the meter is
in the multi-point calibration mode and the meter will retain all calibration data in other ranges. Or else, the calibration
data replaces with new data for all ranges (in single-point calibration mode).
To view calibrated solutions and its corresponding cell constants at respective range, see SETUP main-menus P1.0 and
P2.0.
To completely recalibrate your meter, or when you use a replacement probe, it is best to clear all the calibration data in
the meter’s memory. To erase all the old conductivity and TDS calibration data completely from memory, see SETUP
main-menu P7.0.
Temperature Coefficient: This meter is factory set to a temperature coefficient of 2.1 % per °C. For most applications
this will provide good results. See SETUP sub-menu P4.1 to set the temperature coefficient to different value. See also
Addendum 2, “Calculating Temperature Coefficients” to determine the appropriate temperature coefficient for your
solution.

Instruction Manual
CON 510
Normalization Temperature: The factory default value for normalization temperature is 25 °C. If you need to normalize
to a value other than 25 °C, see SETUP sub-menu P4.2.
4.2
Preparing the Meter for Calibration
Before starting calibration, make sure you are in the correct measurement mode. Otherwise press MODE key to toggle
between measurement modes. When you switch on the meter, it starts up in the last unit of measure when you last shut
off the meter.
DO NOT reuse calibration solutions after each calibration has been performed. 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. Always remember to rinse thoroughly with de-ionized water or a rinse solution after each calibration to
prevent any carry-over.
NOTE: When entering calibration mode, the meter will display the uncalibrated value.
To abort or exit from any calibration mode or SETUP options without confirming any set values, DO NOT press
the ENTER key. Press CAL/MEAS instead. This will retain the meter’s old calibration data in the specific measurement
range or previous SETUP options.
4.3
Calibration with Conductivity Standards 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. Default is 0.50; allowed window is 0.40 to 1.00.
Instead of calibrating for TDS directly, you can calibrate the CON 510 bench meter by:
1. calibrating to conductivity standards and then
2. entering the appropriate TDS conversion factor into the meter.
To determine the conductivity to TDS conversion factor for your solution:
Addendum 2 lists some commonly used conversion factors.
Addendum 3 describes how to calculate the TDS conversion factor for other solutions.
Enter the TDS conversion factor into your meter as described under SETUP sub-menu P3.4.
4.4
Calibration for TDS Standards Directly
The factory default setting for TDS conversion factor is 0.50. If your solution has a different TDS factor, you can improve
the calibration accuracy by setting the correct TDS factor (0.40 to 1.00) prior to calibration in SETUP sub-menu P3.4.
4.5
Selection of Automatic or Manual Calibration
This meter is capable of performing either automatic for Conductivity measurement mode or manual calibration method
for both Conductivity and TDS measurement modes. In the automatic calibration mode, the meter automatically detects
and verifies the appropriate known calibration standards solutions being calibrated before accepting these particular
calibration standards as one of its calibration values in a specific measurement range. This automatic calibration mode
frees you from cumbersome calibration procedure. While in the manual calibration, non-standards calibration values can
be used for calibration, in which you can manually input the appropriate values as your desired calibration standards in
each specific range.
Proceed to SETUP main-menu P5.0 to select the type of calibration method before performing calibration.

CON 510
Automatic Calibration (Only for Conductivity)
In the automatic calibration mode, the CON 510 bench meter is capable of accepting either single-point or up to 4 points
for multi-point calibration with maximum of 1 point per specific measurement range using known calibration standards
values which include: 84 µS/cm (0 – 200.0 µS/cm), 1413 µS/cm (0 – 2000 µS/cm), 12.88 mS/cm (0 – 20.00 mS/cm) and
111.8 mS/cm (0 – 200.0 mS/cm).
NOTE: You need to set your desired option i.e. number of calibration points in the SETUP main-menu P5.0 before
performing calibration.

MEASUREMENT
The CON 510 bench meter measures up to 5 different measurement ranges with auto-ranging capability which
automatically detects and promptly switches to the appropriate range. The meter also allows measurements to be taken
with automatic or manual temperature compensation. The factory default is ATC on.
ATC basically compensates for any temperature variances of measured sample solution temperature automatically from
the normalization temperature set. Default normalization temperature is 25.0 °C (77.0 °F). However if you need to adjust
the default value from 15.0 to 30.0 °C, you may access SETUP sub-menu P3.4 first before measurement.

PROBE CARE AND MAINTENANCE
Keep the Conductivity/TDS 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 probe with deionized or tap water before storing. Never scratch the
bands with a hard substance. Do not strike the probe against any hard surface.
Do not make continuous contact with your solutions. Readings will rise over a period of time
while you soak your probe.
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 deionized water. Recalibrate the meter after cleaning the
probe.
The conductivity probe (Order Part No. EC-CONSEN91W/ 35608-50) which is included with
your meter features a removable probe guard to make cleaning easy.
To remove probe guard:
1. Grip yellow probe guard and twist clockwise. The locking notch will release.

13 NOTE: CONDUCTIVITY AND TDS SOLUTIONS HAVE ±1 % ACCURACY AT
25°C ADDENDUM 1: CALIBRATION TIPS
You only need one calibration for measurement throughout the entire range of the meter. If a range was not calibrated,
the meter automatically detects the closest range calibrated and uses that calibration information. However, only the
ranges that were calibrated have maximum accuracy.
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% F.S. accuracy.
If you are measuring in the mid-ranges and you washed the probe in deionized water and stored it dry,
calibrate the meter at least once a month.
Wet the probe for 10 minutes before calibrating or taking readings to saturate the probe surface and minimize drift. If you
make measurements at extreme temperatures, calibrate the meter at least once a week.
You should only use the conductivity/TDS probe specified for the meter. This probe has a built-in temperature sensor. If
you use a different probe without a temperature sensor, you must measure the solution temperature separately and
manually enter the solution temperature (see manual temperature compensation section).
14 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 conductivity-to-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 be in mS.
Check your factor by multiplying the conductivity reading by the factor in the above formula. The result should be in TDS
value.

15 ADDENDUM 3: CALCULATING TEMPERATURE COEFFICIENTS
To determine the temperature coefficient of your sample solution use this formula:
Where:
tc = Temperature coefficient
CT1 = Conductivity at Temp 1
T1 = Temp 1
25 = 25 °C
CT2 = Conductivity at Temp 2
T2 = Temp 2
NOTE: A controlled temperature water bath is ideal for this procedure.

3.
Immerse the probe into a sample solution and adjust the temperature coefficient to 0% (that is, no compensation) by
performing the following:
A. From measurement mode, press the SETUP key to enter into [SETUP] mode.
B. Use MI/▲ or MR/▼ key until the lower display shows “P5.0”.
C. Press ENTER key twice. The lower display reads tCO and the upper display shows the temperature coefficient
value.
D. Press the MR/▼ key until the upper display shows 0.0.
E. Press ENTER key to confirm the value.
F. Press CA/MEAS key to return to measurement mode.
Wait for 5 minutes. Note T1 and CT1 (conductivity at T1).
Condition the sample solution and probe to a temperature (T2) that is about 5 °C to 10 °C different from T1, and note
the conductivity reading CT2.
NOTE: Record your results for future reference. Ideally T1 and T2 should bracket your measurement temperature, and
should not different by more than 5 °C.
4.
5.
Calculate the temperature coefficient of your solution according to the formula shown above.
Enter the temperature coefficient you calculated into the meter by repeat step A to C. Use MI/▲ or MR/▼ key to set
the desired value. Press ENTER key to confirm selection and then press CAL/MEAS key to return to measurement
mode.
The calculated temperature coefficient will not be applied to all the meter readings.
