PC Control / Touch Control
4.13.3 Requesting sample data and common variables (REQUEST)
With the REQUEST command you can request sample data (sample
identification 1, sample identification 2 and sample size) or a common
variable during the method sequence. You can choose whether the run
is to be stopped or whether it should continue in the background.
• Sample identification: Select the sample identification(s) to be
requested in the sequence.
• Sample size: If this function is active then the value for the sample
size will be requested.
• Sample size unit: If this function is active then the unit for the
sample size will be requested.
• Common variable: Selects the common variables to be requested
in the sequence.
• Hold sequence: If this function is switched on then the sequence
will be halted for the request. If it is switched off then the method will
continue to run in the background until the following titration, meas-
urement or calibration has been completed.
4.13.4 Acoustic signal (BEEP)
The BEEP command is used to produce an acoustic signal during the
method sequence.
• Number of sounds: Number of tones for the signal in the method
sequence. For PC Control the tone selected in the Control panel
under Sounds and Audio Devices will be used. With Touch Control
the number of sounds cannot be altered.
4.13.5 Signature (SIGN)
The SIGN command can be used for signing a determination at the end
of a method sequence. It must always be inserted at the end directly
before the REPORT command, or at the end of the method sequence if
a PC/LIMS report is to be transmitted automatically. The method se-
quence is automatically stopped as soon as the SIGN command is
reached. At the same time a switch is made to the result display. The
method will only be continued when the method has been signed. The
parameters for signing determinations are described in Section 3.7.5
and 3.7.7.
4.13.6 End (END)
The method sequence will stop as soon as the command END is
reached. This is a good idea if you only want to test the first part of a
method. The END command has no parameters that can be edited.
