2.6 Steps Prior to Calibration
2.6.1 Switching ‘ON’ and ‘OFF’ the meter
Press ON key to switch meter on. All the LCD segments will display momentarily for a few seconds and the
LCD then switches to the last measurement mode. To switch meter off, press OFF key.
2.6.2 Selecting Measurement Mode
The measurement modes available for the pH 510 meter are pH, mV (for ORP) and T emperature, while the Ion
510 meter has Ion, pH, mV and Temperature measurement modes. Select the correct mode of o peration by
pressing the MODE key, and each press takes you to next measurement mode. When selecting a p articular
parameter the respective mode annunciator displa ys at the right hand side of primary display; these inclu de
[pH] for pH, [oC] for Temperature, [ppm] for Ion Concentration and [mV] for Millivolt.
2.6.3 Meter Reset
On first use, it is not necessary to reset meter before calibration as it has been factor y-calibrated. However if
you wish to reset the meter to factory default refer to Section 5.4.
NOTE: Re-calibration of meter is required before meas urement after the meter is reset. Likewise if you wish to
prepare a new set of measurements, you may reset all the last calibrated pH values simultaneo usly for added
convenience. Caution: All calibration values and memory data will be erased upon activation. Re-
calibration is required.
2.6.4 Selecting pH Buffer Standard
The meter is capable of calibrating based on either USA or NIST pH buffer standards. Pleas e refer to Section
5.3 P3.0 for details on how to change the USA buffer standard to the NIST standard on the meter itself. Refer
to Section 8.3 for more details on pH buffer standards available.
NOTE: Remove protective rubber cap or storage bottle (if any) from the electrode before proceeding with
measurement or calibration. Take care not to exert too much force as this may cause damage to the electrode.
Whenever the electrode is not in use, put it into storage bottle or protect the electro de with the rubber cap
provided. Refer to the Section 6 on Probe Maintenance for more details.
3 CALIBRATION
3.1 pH Calibration
The 510 series bench meter is capable of multi-point c alibration (up to 5 points) for high accuracy acro ss the
measurement range. The 5-point calibration offers flexibility of calibrating using either USA or NIST buffer
standards with their 5 internationally accepted calibration points namely:
USA standard buffer options: pH1.68, 4.01, 7.00, 10.01, 12.45
NIST standard buffer options: pH1.68, 4.01, 6.86, 9.18, 12.45
For ATC measurements, attach the temperature probe to the meter. The ATC mode annunciator sho ws on the
display. Insert the probe into the solution to be measur ed so that the s ample temper ature can b e recorded an d
pH readings automatically temperature compensated. If ma nual temperatu re compens ation is preferre d, do not
plug a temperature probe into the meter.
DO NOT REUSE SOLUTIONS AFTER CALIBRATION. Contaminants in the solution can affect the calibration,
and eventually the accuracy of the measurements.

Instruction Manual pH 510/ Ion 510
One point calibration (Offset calibration) should only be carried out with pH 7.00 or pH 6.86; otherwise
calibration will not be accepted. For Slope to Slope calibration (t wo points calibratio n), the first calibration point
will only be successfully registered in the meter after the second point calibration has been completed.
It is recommended that you perform at least a 2-point calibration using buffers that bracket (one above and one
below) the expected sample range, starting with pH 7 buffer first. Select a pH 1.68, 4, 7, 10 or 12.45 buffer in
sachets or bottles from standard buffer solutions.
All new calibrations will replace the existing stored calibration data.
1. Press ON/OFF key. All the LCD segments will be displayed
momentarily. The LCD switches to pH measurement mode. If
necessary press MODE key to select pH mode.
NOTE: The meter starts in the same measurement mode that it
was switched off.
2. The customized LCD display will indicate the following:
Display Remarks
MEAS Measurement mode is selected
pH Unit of measurement
o
C Measured temperature reading
ATC Automatic Temperature Compensation
(If temperature probe or “All-in-One” probe is
connected)”
3. Rinse the pH electrode well with deionized water or rinse solution.
If using the ATC function with a separate temperature probe,
thoroughly rinse the temperature probe as well. (Do not wipe the
electrode or the temperature probe as this may cause a b uildup of electrostatic charge and will create calibration and
measurement instability!).
One Point Calibration
4. Select the first pH buffer, pH 7.00 (or pH 6.86) and pour some into
a clean container.
5. Dip both probes into the standard calibration buffer. The end of
the probe must be completely immersed into the buffer. Stir the
probes gently to create a homogenous solution.
6. Press CAL/MEAS key to enter the pH calibration mode. The
annunciator [CAL] appears on top of the LCD to indicate the
meter is in pH calibration mode. The upper display will show the
measured reading while the lower display indicates appropriate
pH standard buffer solution being used.
NOTE: The meter automatically recognizes the buffers in the
buffer standard you have set in the SETUP mode, i.e. eith er USA
(pH1.68, 4.01, 7.00, 10.01 or 12.45) or NIST (pH1.68, 4.01, 6.86
9.18 or 12.45) buffers.
