Display
When running an experiment, the display allows to see the actual parameters. It is divided into three fields:
•
The
upper left
field shows:
o
a flashing
symbol to indicate there is a possible dangerous condition on the output
sockets.
Avoid to contact the outlet sockets and cables!
o
the highlighted measured parameter. Use the
keys to choose another parameter in this
field.
•
The
upper right
field shows the other 3 parameters.
•
The
bottom line
shows date and time at the right and the actual combination of method and step at
the left when such a procedure is running, no indication when running a manual procedure.
•
The
bottom line
is also used for system or error messages when required.
More details to be read:
•
The unit of the parameter that is being kept
constant
is given with
