The instrument will switch off automatically after 10 minutes of inactivity
(i.e. no key presses). To disable the auto-off function press and hold the Up
arrow key whilst switching the unit on. “Auto-off disable” will be displayed
across the screen. When the unit is turned off the auto-off function will be
re-enabled.
To change the instrument temperature units between °C and °F, press and
hold the MODE key for 3 seconds.
When the instrument is turned on a single press of the CAL and backlight key
will turn the backlight on. Another press will switch the backlight off. When
the backlight is on it will automatically turn off after 10 seconds. If the low
battery icon is showing the backlight function will not work.
If mV is selected instead of pH the instrument will read the voltage generated
by a pH, redox or ion type electrode within the range of ±1000mV.
11

SECTION 3 - Temperature Adjustment
Model 570 is supplied with a temperature probe enabling automatic temperature
compensation to be used. If the probe is disconnected then manual temperature
compensation can be used instead.
3.1 MANUAL TEMPERATURE ADJUSTMENT
If the temperature probe is disconnected ‘MANUAL’ will be displayed above
the temperature value. To manually adjust the temperature press or hold the
Up or Down arrow keys to adjust the temperature in whole degrees.
Note that manual temperature adjustment can only be performed if the
temperature probe is not connected.
3.2 AUTOMATIC TEMPERATURE CORRECTION (ATC)
When the temperature probe is connected the 570 meter will automatically
detect the connection and the temperature will be displayed continuously on
the screen. The pH reading will be automatically compensated depending on
the temperature of the sample being measured. The ATC range is 0 to 100°C
(32 to 212°F). If the temperature probe is removed the temperature will be
displayed for 10 seconds.
‘Hi Temp Err’ is displayed if the readings are above 100°C.
‘Lo Temp Err’ is displayed if the readings are below 0°C.
12

SECTION 4 - Calibration and Measurement
Before performing a measurement the instrument must be calibrated. It is
recommended that the instrument is calibrated daily to achieve consistent and
accurate results. Model 570 has a 2 point calibration process. The rst calibration
point MUST be buffer pH 7.00. The second calibration point depends on the
acidity of the solution which is to be measured. For samples with a pH around
5 the second calibration point should be 4.01 pH buffer. For samples with a pH
around 8 the second calibration point should be 10.01pH buffer. Always rinse
the pH and temperature probes in de-ionised water before placing in each buffer
solution. If the ATC probe is connected the instrument automatically compensates
for the resulting change in electrode response due to temperature during the
calibration process.
Press the ON/OFF key to switch the instrument on. If the temperature probe
is not connected ‘MANUAL’ will be displayed above the temperature value. If
manual temperature adjustment is being used, the temperature of the solution
must be measured using a thermometer so that the temperature can be manually
adjusted.
Place the pH electrode and temperature probe into 7.00 pH buffer solution and
allow the reading to stabilise. Stir then press and hold down the CAL key for 3
seconds. Auto-Cal will ash up on the display and then the current reading will be
displayed. Once the reading has stabilised press the CAL key, rinse the electrode
and temperature probe in deionised/distilled water and place them into 4.01 pH
or 10.01 pH solution and allow the reading to stabilise, again stir the solution to
remove any air bubbles. To nish press the CAL key, ‘Calibrated Ok’ will ash up
and the display will show the solution value of the buffer.
To abort the calibration point at any point press the ON/OFF key and the meter will
revert back to any previous calibration values.
During the calibration process the instrument will automatically detect the buffer
solution. However if you know the exact pH value for the buffer at a given
temperature (temperature coefcient) you can change the offset BS (buffer
solution 7.00pH) and slope BS (buffer solution 4.01 or 10.01) by using the Up
or Down arrow keys. Refer to your calibration solutions/capsules temperature
coefcients before any alterations are carried out.
13

‘FAIL’ will be shown if 7.00 pH buffer isn’t used as the rst calibration point.
If the electrode and buffer solution’s combined error is greater than 0.5 pH
or 30mV then ‘Error I/P’ will be displayed and the calibration aborted. If the
electrode and buffer solution’s combined error is greater than 30mV then ‘FAIL’
will be displayed and the calibration aborted. If the electrode and buffer solution’s
combined slope error (4.01 or 10.01) is greater than 0.5pH or 15% ‘Slope error’
will be displayed. If the slope error is greater than 15% the ‘FAIL’ will be displayed.
If an error is displayed during a correctly performed pH calibration this can be
investigated using the mV reading from the pH electrode to determine if the
electrode needs to be replaced. With the instrument in mV mode place the
clean/conditioned electrode and temperature probe into buffer pH 7.00 at a
temperature of 25°C and leave for 30 seconds to stabilise. Record the mV reading
(Asymmetry Potential). Rinse the electrode and temperature probe in distilled or
deionised water, blot and repeat the process in buffer pH 4.01. Record the mV
reading and calculate the difference between the two to obtain the span.
Example:
Reading at 7.00 pH: 4 mV
Reading at 4.01 pH: 178 mV
Span = 178 – 4 = 174mV
In order to calculate the slope percentage (Condition), divide the calculated span
by the theoretical span and times it by 100. The theoretical span between 7.00
pH and 4.01 pH is 176.9 mV.
Slope % = 174/176.9 x 100 = 98%
If your results are below 85% or your mV reading exceeds ±30mV at 7pH, then
you will need to replace the electrode.
Once the instrument is calibrated the sample can be measured. Place the pH
electrode and temperature probe into the sample and allow to stabilise.
If ‘Over Range pH Err’ is displayed the readings are higher than 16pH or 1000mV.
If ‘Under Range pH Err’ is displayed the readings are below -2pH or -1000mV.
If ‘No Probe Err’ is displayed the pH electrode is not connected.

SECTION 5 - Care and Maintenance
Over time the electrode sensor will degrade, but regular calibrating, cleaning and
the correct storage will prolong its life. The epoxy bodied combination electrode
supplied with this instrument is suitable for the majority of tests carried out in
aqueous solutions. For other applications, such as low ionic strength, Tris buffers,
high temperatures and strongly acidic solutions a more suitable pH/reference
electrode pair may be required. Details or advice are supplied on request
([e-mail]).
If the electrode readings are slow or erratic, place the electrode into cleaning
solution or 7.00 pH solution for at least half an hour to one hour before testing
again. The temperature probe and pH electrodes are not waterproof and cannot
be fully immersed in water. It is recommended that the instrument is calibrated
daily to achieve consistent and accurate results.
The following general guidelines indicate the care and maintenance required:
Always rinse the pH electrode with cleaning solution or deionised water before
next use.
Electrodes should be stored:
● away from direct sunlight
● in a vertical position
● within their specied temperature range
Always ensure the electrode is used within its specied temperature range. Ageing
of electrodes used above their specied temperature is rapid and irreversible.
DO NOT touch the sensitive glass pH membrane or reference junction. Excess
droplets of solution may be removed by gently blotting with lter paper or tissue.
DO NOT rub the electrode as this may induce an electrostatic charge.
During use ensure the electrode is rinsed between each measurement to eliminate
the contamination of solutions.
15

5.1 BATTERY REPLACEMENT
Replace the battery when the battery icon is low.
This meter will continue to measure accurately but after further usage the meter
will display ‘FLAt bAT’ and shutdown.
Unscrew the screws on the back of the meter and replace with three AAA
batteries ensuring that the polarities are correct.
