RS  760-6964 or 711-8149 or 289-7109 or 178-059 

I find all but what to buy ? And are different sizes. Please what to order ?

Regards
Mike

SeanB:
First one is small (9mm) and will allow you to work with mains AC up to 300VAC or 400VDC, so will be fine with the meter.  So probably the best compromise as you really do not want to use these meters at higher voltage.  Lowest capacitance as well and likely the fastest acting.

You also get them in a pack of 10, so will have 8 left over just in case. Pretty cheap as well.

Morning
I will order today.
Have a nice day

Hi,

I am thinking of adding some input protection to the UT61E. 

MOVs are fast but low current and will add capacitance.
GDTs are slower but high current and very low capacitance.

Can we use a combination of MOVs & GDPs for ever better response?

On the other hand I see that the tracks from the GDPs are very thin.
So is there any point to add the protection with such thin tracks?
Look for example the one that goes from SG1 to R28.
forget the above...

Thanks.
George.

Yes. Add enough MOVs to protect you until your GDTs react. The more the better (well, two MOVs is probably enough...)
