Working With Custom Buffers
If a custom buffer was set in SETUP menu, it can be selected during calibration
by pressing the ARROW keys. The “C1” or “C2” tag will be on once selected.
Press
u
if you want to modify the custom buffer
value. The buffer value will start blinking. Use the
ARROW keys to change the buffer value.
After 5 seconds, the buffer value is updated. Press
u
if you want to change it again.
Note
: Custom buffer value can be adjusted in a ±1.00 pH window around the
set value during calibration. When a custom buffer is displayed, the “C1” or
“C2” tag is displayed.
First Calibration Point
When performing a new calibration, or adding to an existing one, the user
has a choice how the first new calibration point will be treated in reference
to the existing calibration point. This is selected in SETUP by the parameter
FIRST CALIBRATION POINT. The two SETUP selectable options are “POINT” or
“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).
