best voltage tester

[trypod]

For RCD tests locate a socket either in your home/workshop/office that has been checked and tested with a known correct value and ensuring that the circuit is protected by an RCD at the consumer unit or a plug in unit . Use this as your MASTER SOCKET and test your instrument with this socket and record value. x1/2,x1, x5

cheers trypod ,
i have recieved the test sheet do i need a checkbox for the continuity and insulation tests as the sheet states the fluke voltage tester ive ordered is the t5-1000with h5 holder and1ac kit from isswww.co,uk for £108.10 it should be here next few days thanks for your replies and help cheers mate

 

[trypod]

You need a checkbox or a set of known value resistors values 0.5 ohm, 1ohm 2ohm 10 ohm for continuity checks and 0.5M ohm 2M ohm 10M ohm 20M ohm 50M ohm for insulation checks

cheers mate looks like i will be buying one of these then now i know why most electricians charge £25+per hour to pay for all costs involved eh mate

 

[Roggi]

Eh tell me if I'm wrong but do you still not need to calibrate your multlifunction tester or seperate's and have a valid certificate each year?

 

[brucelee]

hi mate
as far as i am aware if you check the calibration on a known socket for rcd and zs then use a checkbox for insulation and continuity then you only need to get it calibrated every three years but trypod or someone as clued up as him will be able to tell ya

 

[trypod]

Roggi

It depends on who you are with

Calibration frequency should depend on how often it is used.
so you should use a check box once a month too ensure the readings are in limits and see if there is any change to the readings.

Once you have history you can prove your meter is in calibration

You can also have a log of use for the meter

hi trypod
ive just got the link to ebay for the calcard is that all i need for the continuity and insulation checks as i will by that and get a checkbox at a later date

 

[trypod]

Calcard or checkbox you only need one

 

[brucelee]

thanks mate looks like i will send for that then as its cheaper than a checkbox

 

[Roggi]

Hi Trypod , although you say depends who you are with I still thought you needed a valid calibration cert for joining a part p scheme . I have a megger 1553 and I'm thinking of getting it re calibrated due to cert running out . looking to sign up with elecsa.

 

[trypod]

Calibration certificates do not run out

When you buy a new meter from Megger it may have been calibrated three months before you got it there is a box on their certificated for activation date.

Most suppliers recommend 12 months however it may only have been used five times in that time that is why you need to keep records of checks and use.

Problem is Kev I've never used it, and it's now over a year old.

I thought you had to have annual calibrations done with any scheme, the check boxes etc are just a good way to verify the consistancy of your readings throughout the year.

I recently joined Napit and the inspector said that as long as we had a method in place for proving the readings were consistant ie check box / dedicated socket on a monthly basis then there was no need to have the meter recalibrated. He added that when the readings start to differ thats when calibration is needed.

hi trypod,
in your post to everyone about the calibration cert my cert was dated jan2009 and i only got the megger in august. i have not filled in the date on the cert for activation date as since the course i have not used it instructor on the course told us when we start self employed or working and started to use it then fill in the activation date is this correct.this is why i was asking about the testing calibration on a known socket and checkbox to prove calibration should i fill in the date from the course or when i get going sorry mate if i asking stupid questions just want to get everything right i have a socket near c.c.u. so i will use this for testing purposes is that ok cheers mate

 

[trypod]

That's fine
Date of activation I would put the date you start using it for work

 

[brucelee]

cheers mate,
i was thinking as its a year ago since it was calibrated as new that i would have to get it re-calibrated so as soon as i start to use it for work i will date it thanks kev do the calcards come with idiot proof instructions haha cheers

 

[trypod]

they should do

 

[dufjax]

dufjax are the cal cards any good and are they easy to use mate

I've no idea I keep meaning to buy one.

I think I also read somewhere that Elecsa will accept you using the Cal Card (and recording the values, once a month) instead of getting your tester calibrated.
