Favourite test standards

It is important to setup favourite test standards from the standards library to avoid navigating thorough the entire 
list each time you want to change to a different test. To do this navigate to the ‘Tools’ top level window and select 
‘Manage test standards’. Then move down to ‘Select favourite tests’ and choose only those tests which you require, 
making sure you have the most recent version of each test, unless you specifically want to use an old test standard. 
Tests are greyed out when selected. Simply return to the previous screens to save your selection. The screens below 
illustrate this process.

Performing a breakdown

Select the ‘Home’ tab window using the arrow keys and ‘OK’ button. This 
window offers a summary of information required for a measurement. The 
following image shows a typical setup with the selected standard test, the 
test identification or asset ID comprised of an asset number and two digit 
serial number, the type of oil, required electrode gap, electrode shape and 
finally the stirrer.

When the user selects a particular standard only valid options are 
presented with respect to gap setting, electrodes and stirrer options.

Navigation is simple; up and down arrow buttons move up and down the left side of the window whilst options for 
each line can be scrolled through using the ‘OK’ key, or information 
entered in the case of Test ID.

Test in progress

During a test the screen flashes red warning HV symbols to remind the 
user that a high voltage test is in progress. As a safety measure, any key 
press will immediately halt the test. 

The electrode potential difference is displayed as it ramps up in 
over-sized digits to emphasise the presence of high voltage.  

Between tests there is a dwell time and possibly a stirring action. A count 
down timer indicates period of dwell or stirring remaining.
