1 INTRODUCTION
1.1 Introducing the 510 Bench Series
The pH 510 and Ion 510 bench meters are microprocessor-based which incorporates new ASIC (Application
Specific Integrated Circuit). It is desig ned with convenience in mind, and offers many advanc ed user-friendly
features. The meters are capable of storing and recalling up to 50 data sets in its n on-volatile memory. In
addition, as a space saver, an optional swivel electrode holder can be attached at the either side of bench
meter for resting the electrodes and probes during operation.
The pH 510 meter is capable of m easuring pH/ORP with T emperature; while the Ion 510 meter measures Ion
Concentration/pH/ORP with temperature. It is equipped with a large customized LCD (Liquid Crystal Display)
with simultaneous display of the measured values for easy reading. It is most ideal for routine pH/Ion
Concentration measurement in indoor applications.
1.2 Custom LCD
The 510 meter is characterized by a large c ustom dual LCD. The displa y has mode annunciators for p H, mV,
ppm and temperature readings. The secondar y (lower) display shows the temperature reading simul taneously
with the primary (upper) display that shows the measured values of pH, ppm or mV. Special annunciators such
as units of measure, error message, graphical icons and modes of operation are arranged around both primary
and secondary display to give you a comprehensive yet uncluttered display.

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 momentaril y 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 Te mperat ure , while the Ion
510 meter has Ion, pH, mV and Temperature measur ement modes. Select the correct mode of operation b y
pressing the MODE key, and each press takes you to ne xt measurement mode. When selecting a particular
parameter the respective mode annuncia tor displays at the right hand side of primary displa y; these include
[pH] for pH, [
o
C] 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 factory-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 measurement after the meter is reset. Likewise if you wish to
prepare a new set of measurements , you may reset all th e last calibrated pH values simult aneously 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 eit her USA or NIST pH buffer standar ds. Please refer to Section
5.3 P3.0 for details on how to change the USA buf fer standard to the NIST standard o n the meter itself. Refer
to Section 8.4.1 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 electrode wit h 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 calibration (up to 3 points) for high accuracy across the
measurement range. The 3-point calibration offers flexibility of calibrating using either USA or NIST buffer
standards with their 3 i nternationally accepted calibration points namely:
For ATC measurements, attach the temperature probe to the meter. The ATC mode annunciator shows on the
display. Insert the probe into the soluti on to be measur ed so tha t the sample temperat ure can be r ecorded and
pH readings automatically tempera ture co mpensate d. If ma nual tem perature co mpensa tion is pre ferred, 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.
USA standard buffer options: pH 4.01, pH 7.00 and pH 10.01
NIST standard buffer options: pH 4.01, pH 6.86 and pH 9.18.

Instruction Manual pH 510/ Ion 510
All new calibrations will override existing s tored calibration data at thes e calibration points. I t is recommended
that you perform at least a 2-point calibration using buffers that bracket (one above and one below) the
expected sample range, sta rting with pH 7 buffer first. You can perform a 1-point calibration, but make sure that
the buffer value is close to the sa mple value you are measuring. Select a p H 4, 7 or 10 buffer in sachets or
bottles from standard buffer solutions.
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 Compensati on
(If temperature probe or “All-in-One” probe is
connected)”
3. Rinse the pH electrode well with d eionized water or rins e solutio n.
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 buildup of electrostatic charge and will create calibration and
measurement instability!).
One Point Calibration
4. Select the first pH buffer, say pH 7.00 buffer and pour som e 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.
Figure 1: 1st-point calibration
NOTE: The meter automatically recognizes the buffers in the
buffer standard you have set in the SET UP mo de, i.e. eith er USA
(pH 4.01, 7.00 or 10.01) o r NIST (pH 4.01, 6.86 or 9.18) buffers.
