Doing More with LessDoing More with Less
A brief summary to date
• Biology started electrical safety testing in 1999
• Seaward Supernova and Pat1000 testers were supplied as standard testers
• WinPat software was chosen as the preferred management tool
How it worked…… • A tester was used to perform the electrical safety test on
an item. Test data were temporarily stored in the tester• An item record was then manually added into the
Winpats software running on a personal computer. Information keyed in at this stage covered item location, asset number, serial number, class of test, retest interval etc…..
• Actual data about the test was then uploaded onto the computer via a hardware link from the testers memory
• The two parts of data were then combined in the Winpats database (a Microsoft Access database) which was located on one of the School’s servers
So why change anything?
The School was faced with the reality of regularly retesting in excess of 5,000 items and few resources to perform the task. This led to a
review of our complete process.
Issues Identified• Test were slow to perform – lots of buttons and
keystrokes for each test• Too much information was being kept about the
test – all we needed to know was: did it pass or fail?
• Two data entry points for each test• Data stored in the testing unit was susceptible to
being deleted prior to being uploaded to the computer – this is a problem with multiple users of the Supernova tester
• Winpats software was perceived as not being user friendly
How can testing be improved?
• Perform pass or fail testing with a simple tester
• One data entry point for ALL required information – including retest management
• Easier data entry
• A more portable system that suits the layout of the building and lab areas
How to handle the data entry?
• Use a web based system for single point data entry into a database located on a central server – Users need access to an active web browser
• Develop browser windows that will suit both portable data entry via a Pocket PC (with wireless network access) and standard notebook or desktop computers
• Provide an easy method to list retest due items

An overview of data entry
First logon to this web address
Note……. You can test drive this software by going to the site above and using “test” for the username and “test” as the password. A sample
barcode number of 67476 will allow you to evaluate the software. The test login will not allow you to save any changes made.

Pocket PC (PDA)
Logon Screen
OR
Standard Computer BrowserLogon Screen
• An individual who has completed the University training course in electrical safety testing is issued a username and password
• When a person logs on to the system, their name is automatically registered as the one who will be performing the electrical safety test – this eliminates the need to retype entries
• The logon screen also makes the database information more secure
An overview of data entryWhy a user logon screen?
An overview of data entryThe Main Menu Screen
For new items (or previously untested items) select this option and click “Submit”
at the bottom of the screen
To find details of a previously tested item by using its barcode number select this
option, enter the barcode number in the box provided and click “Submit”
To locate items that are due for retesting select this option and click “Submit”
The Administration Screen allows those with admin rights to manage usernames, passwords and test locations - select this
option and click “Submit”
An overview of data entryAdding a new item….
After clicking “Submit” you will be asked to confirm the updating of the database
If any boxes remain incomplete you will see this error message
An overview of data entryHow do I find items needing
retest?Select “Find EST Barcode” from the
main menu screen
Then click “Submit”
An overview of data entryHow do I find items needing
retest?
Select “Other Search Options” from the main menu screen
Then click “Submit”
An overview of data entry Updating the test…..
After clicking “Submit” you will be asked to confirm the updating of the database
If any boxes remain incomplete you will see this error message
An overview of data entryEntering short term tests…..
Use EST barcode numbers as you normally would in this box…..
Select “Short Term” in the Retest box
Please note that “Short Term” tested items will not appear in any of the
retest due lists – they are ONLY one-off tests designed for items that are
not permanently located within Biology (or Biology related) areas.
From the “Add New Entry” item in the main opening menu:
Other ways to find items that need retesting
Rapid retesting identification by the smart use of identifying
labels
An overview continuedNew tested/retest labels…..
The current use to labels
Current test sticker show the date tested and person that performed the test (in this case number 4) (this label will be replaced - see
next slide)
University Asset number (only used on major equipment items)
(this remains the same as previous)
EST barcode label (this remains the same as previous)
An overview continued The new tested/retest label…..
Colors and test dates shown are for demo only and may change
Color indicate the year a retest is due – based on a 5 year cycle
The following dates are valid for tests being performed in 2004
For 6 month or 1 year retest due
items
Will not be used till next year
For 3 year retest due items
Will not be used till next year
For 5 year retest due items
Cycle repeats starting 2010

The above labels are used on ALL tests performed
White
Orange
Yellow
Green
Pink
White – again….
• Any of the above items that are likely to remain fixed in one location will only require a EST tested/retest label (ie no EST barcode) using a 5 year retest color
• Any of the above items that are used in higher risk areas should have EST barcodes and EST tested/retested labels attached of the corresponding color for the retest due date
An overview continuedTesting IEC cords, power boards and
extension leads…..
An overview continued What if something fails the test?
If an item fails electrical safety testing choose “FAILED” from the “ReTest” menu
-Then enter the reason the item failed in the “Comments” box – YOU MUST COMPLETE THIS ENTRY IN ORDER TO PROCEED
- After the “Submit” button is clicked an email will be sent to [email protected] with details of the item that failed
- In addition, THE FAULTY ITEM MUST BE CLEARLY MARKED FAULTY WITH THE DO NOT USE – ELECTRICALLY UNSAFE LABEL PROVIDED
Reminders……
• When testing equipment with a physical ON/OFF switch, ensure the switch is ON before starting the test
• Check that the “earthing clip” from the TNT tester (or other tester model) is attached to a suitable metal part of the item being tested
Confused about what is double insulated?
Sometimes an item with no earthing points is not marked as double insulated. Our technical staff can check it out and, if compliant, give it a sticker. If it has internally earthed components, they will add a test point,
usually a stainless steel bolt near the mains inlet.

What about items in the area that may not be used in the
near future?
Think about the use of these labels
• Andrew Daddow for his database and programming skills
• The many technical staff within Biology that have contributed to the design and testing of this solution
• Software products used include: – MySQL (open source – no cost)– PHP (open source – no cost)– SQLion (purchased software used for converting the old
database information to SQL – Approx $70 Aust)
