To set one of the Temperature options:
• Press
while in
pH Measure
mode.
• Press
.
• Use
or
to select the Temperature option.
• Press
and use
or
to highlight the
desired Temperature option you wish to modify.
• Press
and use
or
to highlight the
desired option (for Temperature Source & Unit options) or use
or
to adjust the temperature value between
the displayed limits (for Manual Temperature option).
• Press
to confirm your selection (for Temperature Source
& Unit options) or press
to save the current value (for Manual Temperature option). Otherwise, press
to cancel operation.
Calibration
This option allows the user to setup desired parameters related to the calibration.
Buffer Entry Type
Three settings are available for the pH buffers used for electrode calibration:
Automatic
- the instrument automatically selects the closest buffer to the measured pH value from the
predefined buffers chosen in the option
Edit Buffer Group
.
Semiautomatic
- the instrument automatically selects the closest buffers to the measured pH value from all
available buffers and you can choose the one used, from standard and custom buffers.
Manual Selection
- the desired pH buffer is manually selected from all available buffers (standard and
custom).
To set the Buffer Entry Type:
• Press
while in
pH Measure
mode.
• Press
.
• Use
or
to select the Calibration option.
• Press
and use
or
to highlight the
Buffer Entry Type option.
• Press
and use
or
to highlight the
desired option.
• Press
to confirm your selection or press
to
cancel operation.
1st Cal. Point
Two options are available for the 1st Cal. Point parameter: Point and
Offset.
Point:
A new buffer can be added to an existing calibration. The
electrode slope will be reevaluated with the addition of this buffer
(normal operation).
Offset:
The new buffer calibration point can create a constant
offset to all existing pH calibration data (existing calibration
must have a minimum of two pH buffers).
To set the 1st Cal. Point:
• Press
while in
pH Measure
mode.
• Press
.
• Use
or
to select the Calibration option.
• Press
and use
or
to highlight the 1st Cal. Point option.
• Press
/
as desired.
• Press
to return to previous menu.
Edit Custom Buffers
If special custom pH buffers are required during calibration, the
Edit Custom Buffers option is available. Up to five pH custom
buffers can be added. If a custom buffer is used, the user must
verify it’s value at the temperature of calibration.
To edit/set the Custom Buffers:
• Press
while in
pH Measure
mode.
• Press
.
• Use
or
to select the Calibration option.
• Press
and use
or
to highlight the Edit
Custom Buffers option.
• For a previous set value, press
to set the custom buffer value to “
----
” if desired and confirm the
setting by pressing
, otherwise press
to edit the selected custom buffer.
• While in edit custom buffer menu press
to set the custom buffer value to 7.000 pH and then use
or
to set the desired custom buffer value.
