Digital manometer

[tegsy1]

Hi all, I recently bought a digital manometer,the only problem is the readings
are all over the place,do they have to be calibrated from new.

No ,the calibration shoud be ok from new,you may have to reset every time you turn on,I know we do'nt like doing it,but read the instructions,if you have thrown away in the excitment of getting a digital tester,should be on manufactorers web site
Mine works Ok,just amazed how combi boilers I have tested this week operating on 584 m/b on high flame were as before around 10.6 m/b

digital is like anything electronic they can go wrong and give dodgy readings..u cant go wrong with the tried and tested liquid manometer i am an old git and hate all the clamour for digital this and thati should have been a machine breaker

Hi Newbie, I was fed up of the water going dirty in the manometer so I added
a touch of red food colouring,works brill and you can always get the level spot on. Its better than the liquid you can buy for the manometer.

yes got a regin one and the fluid is 8 quid for a spit worth

Try the food colouring trick,lasts ages and its about 80p a bottle.

Think I lost the instructions but will follow your advice.Thanks.

The glass "U" tube manometer is a good buy. The plastic ones usually can't be read after a couple of weeks.
I don't know about using food colouring in plastic manometers though!

I imagine they might discolour. Lets know if they do.

Hi Bernie,the food colouring doesnt discolour,Ive had it in my manometer for about 3 mths,still perfectly readable and accurate.
