Press SEND ⑤ to send the formatted command ⑥.

LOGGING

Overview
Logging uses recording channels to capture live data; channels can be set to record values from any channel on an active instrument at specified time intervals. A maximum of  8 parameters can be logged from any active channel. Varying measurement intervals can be set alongside units and plot line colour. The results are plotted on one of the  two available graphs and can also be viewed in a table and exported as a .CSV (comma separated values), a .TSV file (tab separated values) or as a plain text file. The graph  provides advanced zooming and panning functions, allowing for efficient data analysis.

Logging Setup
Firstly, select logging mode ①. Before starting, select the primary and secondary units to record on the Y axis using the drop-down boxes on either side: Graph 1= ②, ③  Graph 2= ④, ⑤ The X axis will always show time (absolute or relative).
The bar ⑥ can be used to change the proportion of each graph shown.
Logging Controls
Once the recording channels have been setup, data logging is controlled using the logging controls:
Run – ⑦ Start logging selected data
Stop – ⑧ Stop logging selected data
Save – ⑨ Save the logged data as a file (CSV, TXT or TSV)
Clear – ⑩ Clear all logged data.

NOTE
‘Save’ will only save the logged data. To save instrument setups, see File.
TSV – Tab Separated Values, CSV – Comma Separated Values, TXT – Plain text file.
CAUTION
The ‘Clear’ action is irreversible. Save any important data before clearing.

Recording Channel Setup

NOTE
Ensure Y axis units have been set before setting recording channels, see Logging setup for more details.
Line Plot – Select the preferred graph ① to show the logged data on using the drop-down box. This can also be set to hide; the data will not be shown on the graph but will still be logged. The colour of the logging line can be selected from the colour picker ②.
Instrument – Choose which instrument ③ to log the data from using the drop- down box. Only instruments that have been allocated a control panel will be available in the drop down.
Channel – Select the channel ④ to log data from the chosen instrument.
Measurement – Select the measurement units ⑤ to be logged. Ensure the units match the units set on the graph.
Interval – Set the logging interval ⑥ in seconds, the minimum is 250ms. To ensure the best results, check the minimum sampling rate specifications in the instrument’s Instruction Manual.

View

When the data is recorded and displayed on a graph, it can be viewed in several different ways:
Show Values – Click and drag the mouse across the graph ① to show the details ② of that specific point in the logged data. This can be dragged along the entire data line to  show any point within the log. The following actions are available for graph navigation. To begin, click on the graph area:

SEQUENCING

Overview
Sequence numbers are limited only by the number of channels that are available; each sequence is allocated to a specified channel on an instrument. Two different parameters  can be added to each sequence, along with two events. A range of built-in step options are available, including: sine wave, triangle wave, ramp, and step.
Sequencing Setup

Firstly, select Sequencing mode ①, then select Add ② to start creating a sequence.
Each sequence is allocated to a specified channel. Before the sequence can be created, an instrument ③ and channel ④ need to be specified. Use the drop-down boxes to  select these.
The sequencing tools will now be available to use.

NOTE
The sequence update period is limited to 250ms. Dots represent the update points, with linear lines joining points. i.e. A sine wave set for 1s period will have 5 points and be  represented as a triangle.
Adding Steps to a Sequence
Each individual channel sequence can contain a primary and secondary parameter, and an event for each parameter. These are selected using the radio buttons and colour  coded for identification.
To add a step to the sequence, select the parameter or event, then select a shape from the four options in the step selection ⑤. Each shape has a unique pop-up window ⑥  that gives the editable parameters for that shape:
Each step has the option to Insert, Add or Cancel:
INSERT – Place the step BEFORE the selected step.
ADD- Place the step AFTER the last step.
CANCEL – Return to the sequence without making any changes.
There is also an option to name the step.
When creating a step for an event, additional options are available to add a condition and an action.

Editing a sequence

Steps that have been added to the sequence can be selected using the drop-down box ①. The steps are highlighted in the sequence with a faint box the same colour as the unit/event.

① – Step selection drop down
② – Deletes the current step
③ – Edits the sequence step selected in ①
④ – Saves a sequence file
⑤ – Opens a sequence file
⑥ – When ticked, causes the sequence
to start when logging starts
⑦ – When ticked, logging will stop
when the sequence stops| ⑧ – Starts logging data, if ⑥ is ticked
the sequence will also start
⑨ – Stops logging data, if ⑥ is ticked
the sequence will also stop
⑩ – Saves log data to file
⑪ – Clears all log data
⑫ – Start/continue the sequence
⑬ – Pause the sequence
⑭ – Stop the sequence
---|---

Steps can be deleted once they are selected, using the trash can button ②.
Steps can be edited once they are selected, using the edit button ③.

Saving/Loading a Sequence
Sequences can be saved using the Save button ④ and loaded using the Load button ⑤.

NOTE
‘Save’ will only save the sequence settings. To save instrument setups, see File
‘Load’ will load steps for all units, not just the selected unit.
Running a Sequence While Logging
Once the sequence setup is complete, it can be run by selecting Run Sequence ⑥, followed by the Run button ⑧ on the logging controls.
The logging graph will then show the logging results for the running sequence, provided the recording channels have been set to view the channel allocated to the sequence.  See Recording channel setup for more details.
⑧ – Start logging and run the sequence if ⑥ is ticked. ⑬ – Pause the sequence ⑭ – Stop the sequence

Running a Sequence Independently of Logging
Once the sequence setup is complete, it can be run by selecting ⑫. ⑥ must be un-ticked to be able to run a sequence independently of logging. ⑫ – Start/continue the  sequence ⑬ – Pause the sequence ⑭ – Stop the sequence

ERROR LOG AND COMMUNICATIONS

Error Log
The Error Log panel is selected using the icon ① and will present any errors that have been logged.
Each error message ④ has an index number ② and time allocated ③ as a reference point.
