Table 3-2. Automatic Calibration Sequence Set Up Attributes

ATTRIBUTE
Name Allows the user to create a text string of up to 10 characters identifying the sequence.
Timer Enable Check the Enable box to activate an internal automatic timer to initiate sequences using the
calibrator's built in clock. The sequence can be set up to start at a predetermined date and
time. Press the Edit button to configure the Timer.
Timer Start
Timer Delta
Repeat Count
Number of times, between 0 and 100, to execute the same sequence. A value of 0 (zero)
causes the sequence to execute indefinitely.
Input CC
Enable and edit this attribute to specify which of the Digital Control Inputs will initiate the
sequence, allowing the entire sequence to be triggered from an external source, such as a
data logger, where the calibrator operates in a slave mode.
Output CC Enable and edit this attribute to allow the calibrator to control devices that accept logic-level
digital inputs, such as programmable logic controllers (PLCs), data loggers, or digital
relays/valve drivers. This instruction causes the sequence to set or reset the calibrator's
digital control outputs. It is very useful in situations where the control outputs are being used
to trigger other devices that need to be turned off and on in synch with the operation of the
calibrator as it progress through the sequence. The CC Outputs can be used as:
•
•
Specify which of the 12 Digital Control Outputs will be active when the sequence is
operating, or specify which ones to activate/deactivate while running individual steps within
a calibration sequence.
NOTE: once a sequence is finished executing, the Output CC will continue running in its
default configuration as set up through the "Default CCOut" button located at the bottom
right of the Setup>Sequence page; it is recommended that the Default CCOut configuration
be viewed/edited as needed.
Steps Steps are the actions that the Sequence is to execute. NOTE: the first step input in the Edit
Steps page will be the last step executed by the Sequence. (In other words, the Steps must
be input in reverse order so that the first step displays at the top). In addition, it is strongly
recommended that each Sequence end with an instruction to return the instrument to
Standby mode; therefore, the STANDBY step should be the first Step that is input.
Existing steps can be changed (Edit) or permanently removed (Delete). Press the Done
button to accept the Steps and return to the Sequence list. The Step Types include:
GENERATE
STANDBY
EXECSEQ
SET CC OUTPUT
LEVEL
72
Edit this field to set the date and time to start running the sequence.
Edit this field to set interval changes in days and/or hours and
minutes, where the sequence repeats after the set delay time.
12 separate ON/OFF switches assigned to separate calibration sequences, or;
A 12-bit wide bus allowing the user to define activation codes for up to 4095 separate
calibration sequences.
Puts the instrument into GENERATE mode. Similar in operation and
effect to the GENERATE > AUTO function used at the Input and
Control Panel.
Stops generating and ends the sequence. It is strongly
recommended to always insert this as a last step of the Sequence.
Used fto create nested sequences, this step calls a previously
configured sequence to be executed at this time. The "calling"
sequence will resume running when the "called" sequence (selected
in this EXECSEQ step) is completed. A maximum of 5 levels of
nested sequences is allowed.
Allows the sequence to activate the digital control outputs. Similar to
the OUTPUT CC attribute, but can be set and reset by individual
steps. It is very useful in situations where the control outputs are
being used to trigger other devices that need to be turned off and on
in sync with the operation of the calibrator as it progresses through
the sequence.
Like EXECSEQ, this step type executes a Level (Section 3.3.8).
