NOTES

We exceeded the safety specifications wherever possible. However,

we can't be held liable for misuse or bad manipulation.

We simplified the Phase Comparators by not having any parts

to assemble on site. There is no user serviceable parts or user

assembled part in our Phase Comparators.
Only the tip (contact electrode) must be screwed on the front end of

each pole. They generally do not need to be removed by the user.
For other kind of tips and contact electrodes, contact the factory or

your nearest distributor.
Getting regular training on your High Voltage equipment and on the

electrical network / grid you are working on is good practice and will

help in keeping you safe.
Always make a sketch before proceeding with testing High Voltage

and ensure you are fully in control of the testing and understand fully

what is going on. Failure to do so can result in fatal accidents.
