[*WPT>=#] - Wait until the probe temperature exceeds or equals a particular value (# as an integer).
[*WPT<=#] - Wait until the probe temperature decreases to or below a particular value (# as an integer).
The probe temperature is the reading of the standard 400 series or 500 series probe plugged into the
temperature controller. Typically the probe is used to monitor the temperature of the sample in the
cuvette.
[*WRT>=#] - Wait until the reference temperature exceeds or equals a particular value (# as an integer).
[*WRT<=#] - Wait until the reference temperature decreases to or below a particular value (# as an integer).
The reference temperature is the temperature of the metal body of the reference cuvette holder (dual
controller only).
[*WT #] - This program command will cause the script to Wait until the Temperature is stable before
continuing to the next script command in the list. Temperature stability is determined by an algorithm built
into the controller. The parameter (#) determines how often the program sends a status query to the
controller ([F1 IS ?], see Appendix 1 under Instrument Status). Each time this query is received, the controller
returns a status message which includes information as to whether the temperature is still changing or has
met the criteria for being stable (controlled).
The time between status queries is the product of the parameter (#) and the script INTERVAL as defined in
the first line of the script (see the example script in Appendix 3 where the second line sets INTERVAL to 0.6
seconds or 0.01 minutes).
[*WD #] - This program command will cause the script to Wait for an external Data Acquisition Program (DAP)
to set a RESUME flag. The parameter (#) determines how often the program checks to see if the RESUME flag
has been set (the time interval is the product of # and the script INTERVAL as defined in the first line of the
script – see Appendix 3). The flag is the first letter contained in a specific text file (C:\QNW_SC.DAP). When
the *WD command starts, the program opens or creates the file and replaces its contents with the word
ACQUIRE. It is assumed that the DAP, provided by the user or by the instrument manufacturer, is running and
periodically checking the file contents. When the DAP finds the flag set to ACQUIRE, it must do any data
acquisition required then replace the contents of the same file with the word RESUME (actually, any word
beginning with a capital R) and close the file. This latter action will then trigger the *WD command to end and
the program will continue with the next command in the script.
[*BCT +] or [*BCT-] - Turn on(+) or off(-) beeping by the computer whenever a sample holder (current)
temperature report is received from the controller.
[*BPT +] or [*BPT-] - Turn on(+) or off(-) beeping by the computer whenever a probe temperature report is
received from the controller.
[*BRT +] or [*BRT-] - Turn on(+) or off(-) beeping by the computer whenever a reference holder temperature
report is received from the controller.
