OK, then, tell us how you would:

a) test insulation to regulations
b) test earth loop impedance to regulations

without one.


I test them every day,

The question was "how", not "how often".

I look at my house carefully and verify that it has now burnt to the ground.
I know how to do this because I have a friend who works for an insurance
company who told me wht a gutted. burnt out house looks like.
I verify my household electrics are working by using the succesfully
every day or every so often. I have a friend who works in Currys

I suppose you can give your car an MOT test just by looking at it too?

You could earth loop with a multimeter. You'd need a high ampage load (an
electric heater would be ideal), the multimeter on voltage setting
(should
probably be 4 sig figs) and a calculator. Unfortunately, you would also
nee
a clue, which might be more difficult to obtain. ;-)

We had an installation engineer who was the most conscientious in the
department. He never left a job without producing the relevent paperwork.
On
one occasion I found him working out the PSC of the system by pulsing on
and
off the electric heater and applying ohms law after determining the
wattage
of the heater, and using a (calibrated) avo to determine the voltage with
and without the heater working.

I would trust his figures more than from anyone else in the department,
and
from a more modern digital instrument. At least he could back up his
answers
from basic theory, without much reliance on mass produced test
certificates
for over complicated test gear which can't be reliably calibrated by the
operator.

I was having a problem with my gas boiler and wondered if the
thermocouple was working correctly, you can buy meters to this
for the princly sum on $900
http://www.testequipmentdepot.com/fl...rators/714.htm
You can spend another $1000 on "optional extras" if you like :O)

I tested mine with a £5 multlimeter, and it gave the expected 30 millivolt
reading. It turned out that the gas valve was faulty (verified by a
qualified
gas engineer, mind you I had figure that out for myself already!!).
Not that he actually tested it, he just cut the existing thermocouple
(which I had just bought!!) and put a new one in!!
Still as they only cost him about £4, thats the most cost effective way to
do it I guess? (especially if it is faulty, as is usually the case) because
he
is going to have to replace it anyway. He told me 99 times out of 100
it is the thermocouple rather than the gas valve.

The MOT test only (probably) verifies that it is road worthy at the time of
the test.

Slip em a few squid and they will pass it anyway :O)

Way beyond the capabilities of 'Bazzer', who thinks you can use a
mutimeter to test insulation resistance...

Yes you can actually. You just cannot issue the certificate ;-)

not possible with the new machines. now its up to VOSA to say wether the car
has passed or not. not the testing station

So how much does can a casual visual inspection tell you about the
thickness of the brake linings, the amount of play in the wheel
bearings, the accuracy of the steering alignment, the tyre pressures,
and the content of the exhaust emissions?

What about backstreet testing stations that aren't issuing the new style MOT
certificates yet?

A lot of those things aren't covered by a full service these days.

All monitored my the car management system in my car, I can get
a read-out (MOT) at any time.

Isn't this "car management system" part of the car that it is testing?
Given that it must be subject to the same mechanical and thermal stresses
as the car itself, what verification have you of its state of calibration?

As I am both the driver and 'manager' of the car I am fairly sure I am
calibrated correctly.

Some may disagree :O)
