pH Buffers Note. Displayed only if at least one pH sensor is fitted and Measurement Type = pH.
Buffer 1 Set the type/value of buffer solution 1.
• Supported buffer solutions from table below/user-defined.
Used Buffer 1 Note. Displayed only if Buffer 1 Type = User Defined.
Set the user defined buffer characteristic curve using the five point linearizer table
(pH against °C).
Buffer 2 Set the type/value of buffer solution 2.
• Supported buffer solutions from table below/user-defined.
Used Buffer 2 Note. Displayed only if Buffer 2 Type = User Defined.
Set the user defined buffer characteristic curve using the five point linearizer table
(pH against °C).
Hold Outputs Set to automatically hold current outputs and alarms whilst a calibration is being performed.
• Disabled/Enabled.
