4. CALIBRATION
4.1. Important Information on Meter Calibration
When you recalibrate your meter, old pH and conductivity calibration data are replaced on a
point by point basis. For example, if you previously calibrated your meter at pH 4.0, 7.0, and
10.0, and you recalibrate at pH 7.0, the meter retains the old calibration data at pH 4.0 and pH
10.0.
To completely recalibrate your meter, or when you use a replacement probe, it is best to set
the meter to its factory defaults and recalibrate the meter at all points.
To reset the meter to its factory defaults:
1. While in Measurement mode, press
CAL/MEAS and hold for 3 seconds.
2. The meter will prompt RST in the lower display
and CAL in the upper display. See Figure 6.
3. Press ENTER to reset your meter to its factory
defaults. If you do not want to erase existing
calibration data, press CAL/MEAS to escape
this mode.
For information on how to calibrate your meter:
See Section 4.3 on page 8 for Temperature calibration.
See Section 4.4 on pages 10 for pH calibration.
See Section 4.5 on pages 12 for conductivity calibration.

4.2. Preparing the Meter for Calibration
The pH/conductivity/temperature probe included with this meter is designed for use with this
meter only. Do not substitute other types of probes or electrodes. For a replacement probe,
see the “Accessories” section, page 21.
Be sure to remove the protective cap of the pH probe before calibration or
measurement. Always immerse the probe beyond the electrode band.
Immerse the probe in tap water for 10 minutes before calibrating or taking readings to hydrate
the pH electrode surface and minimise drift.
Rinse your probe in DI water after use. Storage in electrode storage solution is ideal.
Alternatively, pH 4.0 or 7.0 calibration standards can be used for short term storage. Do not
reuse buffer solutions after calibration. Contaminants in the solution can affect the calibration,
and eventually the accuracy of the measurements.
Always remove this protective cap
before calibration or measurement
Always immerse the

4.4. pH Calibration
This instrument is capable of up to 3-point pH calibration to ensure accuracy across the entire
pH range of the meter. You can perform 1, 2, or 3 point calibration with standard pH buffers of
4.01, 7.00 and 10.00.
We recommend that you perform at least 2-point calibration using standard buffers that covers
the expected sample range. You can also perform a 1-point calibration, but make sure that the
buffer value is close to the sample value you are measuring.
This meter features three pre-programmed pH buffers (pH 4.01, 7.00 and 10.00). The meter
automatically recognizes and calibrates to these standard buffer values, which makes pH
calibration faster and easier.
Calibrating for 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 DI water or a rinse solution. Do not wipe the probe; this
causes a build-up of electrostatic charge on the
glass surface.
3. Dip the probe into the calibration buffer. The
end of the probe must be completely immersed
into the sample. Stir the sample using the
probe gently to create a homogeneous sample.
4. Press CAL/MEAS to enter pH calibration mode.
The primary display will show the measured
reading while the smaller secondary display will
indicate the pH standard buffer solution.
See Figure 11.
NOTE: If using a pH buffer other than pH 7,
5. Wait for the measured pH value to stabilize.
The READY indicator will display when the
reading stabilizes.
See Figure 12.
press the
or key to scroll up or
down until the secondary display value

6. After the reading has stabilized and the READY
indicator is displayed, press ENTER to confirm
calibration. A confirming indicator (CON)
flashes and disappears. The meter is now
calibrated to the buffer indicated in the
secondary display.
See Figure 13.
The secondary display automatically scrolls to the
next buffer calibration option.
If you are performing multi-point calibration, go to

If you are performing one-point calibration, go to step
10.
7. Press the or key to select the next buffer value you want to calibrate (pH 4.00, 7.00
or 10.00).
See Figure 14.
8. Rinse the probe with DI water or a rinse
solution, and place it in the next pH buffer you
want to calibrate.
9. Follow steps 5 to 8 for all calibration processes
(up to 3 points).
10. When calibration is complete, press
CAL/MEAS to return to pH measurement

4.5. Conductivity Calibration
The Important Information on Conductivity Calibration
Your meter has four measuring ranges. You can calibrate one point in each of the measuring
ranges (up to four points). If you are measuring values in more than one range, make sure to
calibrate each of the ranges you are measuring.
The following table lists the corresponding conductivity range. You should calibrate each
range using a solution that falls between the values in the “recommended calibration solution
range” column.
Conductivity Range Recommended Calibration
Solution Range
0.00 to 19.99 µS 6.00 to 17.00 µS
0.0 to 199.9 µS 60.0 to 170.0 µS
0 to 1999 µS 600 to 1700 µS
0.00 to 19.99 mS 6.00 to 17.00 mS
NOTE:
Minimum calibration value should be 20% of full scale for the specific range. E.g.: The
LOWEST calibration value for the range of 0.00 to 19.99 µS is 4.00 µS.
When you recalibrate your meter, old calibrations are replaced on a range basis. For example,
if you previously calibrated your conductivity meter at 1413 µS in the 0 to 1999 µS range and
you recalibrate at 1500 µS (also in the 0 to 1999 µS range), the meter will replace the old
calibration data (1413 µS) in that range. The meter will retain all calibration data in other
ranges.
To completely recalibrate your meter, or when you use a replacement probe, it is best to clear
all calibration data in memory. To erase all the old conductivity data, see Section 4.1:
Important Information on Meter Calibration.
NOTE:
These meters are factory set to a temperature coefficient of 2.00% per °C. For most
applications this will provide good results. The factory default value for normalization
temperature is 25°C.

4.6. Calibrating for Conductivity:
1. Pour out two separate portions of your calibration
standard and one of DI water into separate clean
containers.
2. If necessary, press MODE key to select
Conductivity Mode. The µS and mS indicator will
appear on the right side of the display.
3. Rinse your probe with DI water, then rinse the
probe in one portion of the calibration standard.
Immerse the probe into the second portion of the
calibration standard. The meter auto ranging
function selects the appropriate conductivity range
(four ranges are possible). Be sure the probe is
free from air bubbles and sufficient calibration
standard is used to cover the conductivity sensor.
Wait for the reading to stabilize. The READY
indicator lights when the reading is stable.
See Figure 18
4. Press the CAL/MEAS key. The CAL indicator
appears above the primary display. The primary
display shows the measured reading and the
secondary display shows the temperature.

5. MEASUREMENT
The READY indicator appears on the display when
the readings stabilise. It will turn off if the readings
start to fluctuate.
NOTE: Be sure to remove the protective cap of the
pH electrode before measurement.
To take readings:
1. Rinse the probe with DI water before use to
remove any impurities adhering to the probe
body. If the pH electrode has dehydrated,
soak it for 30 minutes in tap water.
2. Switch on the meter. The MEAS annunciator
appears on the top center of the LCD. The
ATC indicator appears in the lower right hand
corner to indicate Automatic Temperature
Compensation. See Figure 22.
3. Dip the probe into the sample.
NOTE: When measuring a sample, make sure that
the probe is immersed beyond the electrode band.
See figure in Section 4.2. Stir the sample using the
probe gently to create a homogenous sample. Allow
time for the readings to stabilize. Note the readings
on the display. When the readings are stable, the
READY annunciator appears.
4. To toggle between pH and conductivity
readings, press the MODE key. See Figures
23 and 24.
NOTE: Conductivity readings are auto
ranging and will automatically move to
the correct range (four ranges
possible).

7. PROBE CARE AND MAINTENANCE
Under typical operating conditions, the probe w ill need to be replaced every 6 to 12
months. In extreme applications, the probe may wear out sooner. Proper care and
maintenance will help you receive the maximum probe life and ensure more accurate
readings.
Keep the probe clean. Before use, rinse the probe twice. Be sure to remove the protective
cap of the pH probe before use and always immerse the probe beyond the electrode band.
For the best accuracy, soak your probe in electrode storage solution, pH 4.0 buffer, or tap
water for at least 5 to 10 minutes before calibration.
Gently stir the probe in the solution while you take readings. Tap the probe gently against the
bottom and sides of your container to remove any air bubbles, which may interfere with
accuracy.
Clean the probe thoroughly by immersing it in an agitated mild detergent bath. To clean the
conductivity cell, remove the plastic sleeve and use a cotton swab soaked in isopropyl alcohol
to clean the steel pins. Wipe the steel pins if needed with soft tissue paper. Replace the
sleeve which is necessary for calibration and measurement. DO NOT wipe the pH bulb as it
may cause static build-up. After cleaning the probe, rinse the probe well with clean water.
Recalibrate the meter after cleaning the probe.
Do not strike the probe against any hard surface. Do not immerse the probe in oily solutions.
Store the probe in its cap filled with electrode storage solution. To order a replacement probe
and other accessories, see “Accessories” section on page 21 .
