stat.
The result enters the statistics.
live
The result is shown in the trace win-
dow during the determination and
recalculated each time a new entry
is made in the measuring point list.
Please note that in titrations the live
value may not be quite as up-to-
date as the actual value.
Softkeys
[Copy line]
copies the contents of the selected line into a local
buffer memory.
[Cut line]
copies the contents of the selected line into a local
buffer memory and deletes the selected line.
[Paste line]
inserts a new line before the selected line and enters
the contents of the local buffer memory in it.
[Insert line]
inserts a new empty line before the selected line.
[Delete line]
deletes the selected line.
7.10.1 System variables
The following system variables can be used in formulas.
(xx=any 2 numbers or letters, #=any number)
Rxx Result
RT1 Result for validation
RT2 Theoretical result for validation
RE Result for calculating the system error in validation
Xxx Intermediate result
C## Common variable (of the actual titration or measurement)
EP# Endpoint volume in mL
