It seems that it can test many types of components and is efficient and relatively inexpensive. I would like to share this information with all my friends here.
I purchased a new tester from a UK supplier for £19.72.
Cant' complain about the cost at all!
Looking forward to having a play.
From what I can tell only test zener diodes in A K . All other diodes in the numbers 1 to 3
The terminals connected together are for calibration only.
I will let you know how I get on with when it arrives.
Hi Jorgen,
I have now had some time to use the tester.
It's great at identifying components.
It's more as a guide than anything but I have no regrets of the purchase at all.
It even detects the zener diode up to 30V.
I think it makes a great edition to anyone in to electronics.
I use it for the quick ID of unsorted components.
