Any method can be copied to the open method. To modify the measurement mode and channel
setup parameters of a protected method without altering the original protected method, simply
load the protected method and then use the copy function to save the method parameters to
the open method. The copied method parameters can be modified without using a
password in
the open method and the original version of the protected method is preserved.
Edit / Create
Use the edit / create function to modify the measurement mode and channel setup parameters
of an existing method or to create a new method.
1.
Press the ▲ or
▼ key to highlight Edit / Create in the Method setup menu and press the
f3 (Select) key.
2.
Press the
▲ or
▼ key to highlight an existing method to edit or a new method to create
(only protected methods can be selected) and press the
f3 (Edit) key.
3.
If an existing method is selected, use the numeric keypad on the meter to enter the
password for the existing method and then press the
f2 (Accept) key.
4.
To edit or create the user name, press the
▲ or
▼ key to highlight User Name and press
the
f3 (Edit) key. Select up to nine alphanumeric characters using the ▲, ▼, ◄, ► keys
and the
f2 (Enter) key and then press the
f1 (Done) key.
5.
To edit or create the password, press the
▲ or
▼ key to highlight Password and press the
f3 (Edit) key. Use the numeric keypad on the meter to enter a password (up to six digits)
and then press the
f2 (Accept) key. Make sure to record the password – the password will
be required to edit or delete the method.
6.
To edit or select a new measurement mode and channel-specific setup parameters, press
the
▲ or
▼ key to highlight Mode. Press the
◄ or
► key to highlight the desired
measurement mode and press the
f3 (Select) key. The meter will proceed to the channel
setup menu. Review and update the parameters that will be used for the method and then
press the
f1 (Back) key. The displayed measurement modes are module dependent and
the displayed channel setup parameters are measurement mode dependent.
Refer to the
individual module chapters for detailed information and instructions.
7.
Press the
measure (esc) key to proceed to the measurement mode. The edited method or
new method will be automatically loaded and activated for use in the measurement mode.
Delete
Use the delete function to reset an existing method to the default measurement mode and
channel setup parameters for that channel. The password for the existing method must be
entered before the action can be completed.

Temperature Menu
Channel-specific temperature settings can be viewed and changed in the Temperature menu
within the Channel 1, Channel 2, Channel 3 and Channel 4 setup menus. ATC (Automatic
Temperature Compensation) probes are defined as both separate temperature probes and
those built into electrodes.
Refer to

meters are capable of displaying the temperature units as degrees Celsius (°C) or
degrees Fahrenheit (°F).
1.
Press the ▲ or ▼ key to highlight Temperature Unit in the Temperature setup
menu of the
selected channel.
2.
Press the ◄ or ► key to highlight °C or °F as the displayed temperature units.
3.
Press the
measure (esc) key to return to the measurement mode.
Temperature Input
The temperature source for each channel can be set to any available ATC probe connected to
the meter. Only channels with an ATC probe actively connected will be shown and selectable.
The temperature source can also be set to manual (MAN) using this menu.
One ATC probe can be used for multiple channels. For example, a pH electrode on channel 1
can use a conductivity probe on channel 2 as the temperature source, so a second ATC probe
is not needed when the pH electrode and conductivity probe are measuring the same sample.
1.
Press the ▲ or ▼ key to highlight Temperature Input in the Temperature setup menu of
the selected channel.
2.
Press the ◄ or ► key to highlight any available ATC probe (i.e. Ch2-ATC) as the
temperature source or highlight MAN for manual temperature input. This setting will
determine which options are available in the Temperature Cal menu.
3.
Press the
measure (esc) key to return to the measurement mode or proceed to the
Temperature Cal menu.

Temperature Cal
A temperature calibration can be performed for individual ATC probes or simultaneously for all
ATC probes connected to the meter. A manual temperature value can also be entered using the
Temperature Cal menu if the MAN setting is selected in the Temperature Input menu.
The meter has a relative temperature accuracy of ±0.1°C. ATC probes have varying relative
temperature accuracies, usually ±0.5°C to ±2°C. Use the temperature calibration function only
when necessary.
It is recommended that two NIST-traceable thermometers be used to measure and verify the
calibration solution temperature. Since the temperature offset calculated during the calibration
is applied to all future temperature measurements, recalibrate the temperature if
a different ATC
probe is used.
ATC Probe Temperature Calibration
Prepare and connect all ATC probes to be calibrated to the appropriate module inputs on the
selected channels.
1.
Press the
▲ or
▼ key to highlight Temperature Cal in the Temperature setup menu of the
selected channel.
2.
Press the
◄ or
► key to highlight the individual ATC probe selected in the Temperature
Input menu (i.e. Ch2-ATC) or All ATC and press the
f3 (Select) key.
3.
Place the ATC probe(s) into a solution with a known, stable temperature. It is recommended
that two NIST-traceable thermometers be used to measure and verify the temperature.
4.
Press the
f3 (Edit) key, use the numeric keypad to enter the temperature of the solution and
press the
f2 (Accept) key to save the temperature value and update the offset.
5.
If applicable, press the
▲ or
▼ key to highlight the reference temperature of the next ATC
probe and repeat steps 3 and 4 for each ATC probe connected to the meter.
6.
Once all ATC probes are calibrated, press the
f1 (Back) key to exit the calibration and press
the
measure (esc) key to return to the measurement mode.
Manual Temperature Entry
A manual temperature value can be entered when MAN is selected as the temperature input.
1.
Press the
▲ or
▼ key to highlight Temperature Cal in the Temperature setup menu of the
selected channel.
2.
Press the
f3 (Select) key.
3.
Press the
f3 (Clear) key, input the temperature
value using the numeric keypad and then press the
f2 (Enter) key to save the value.
4.
Press the
measure (esc) key to return to the
measurement mode.
