Question 2

may i know what country is it made in ?

Accepted Answer

The device is made in Canada. Test leads are Swiss-made.

Question 3

Hello, Does this item come with a calibration certificate? Could i request for that for my order?

Accepted Answer

I beleive it does but it has been almost a year since we have ordered so I can't be 100% sure.  Sorry.....

Question 4

This is an expensive but quality device.  Can it handle in-circuit caps (discharged), and is there a good manual for non-engineers?

Accepted Answer

Hello: I bought my unit about 4 yrs ago. there was not a good manual. I am guessing you can go on line and find a manual. I would not recommend this for a non engineer. It can be used for in circuit cap testing, however it might not be accurate depending on the type of circuit.
