16V Doorbell transformer outputing 22V

I got a new Doorbell (16V) and transformer (16V) together 'via contractor pack' to replace the old/dead transformer. Everything is installed and working well but when I tested the output of the transformer using a multimeter it showing 21.99V. Is this ok / acceptable? or is this a faulty transformer that is outputting too much voltage?

Thank you.

Given the price of those contractors packs not unexpected. Nothing to worry about.

It is amazing. The transformer is 14.95 separately.
Or the whole kit including the transformer, the chime and two buttons for 19.95.

Even better ... $12.98 for the kit, actually. Separately it would be $15 for transformer, $10 for the button, and $15+ for the chime. This was a first time transformer job for me and it all went smoothly (except the 22V reading). Hopefully it lasts awhile.

Thanks again for the help.

These small transformers tend to have voltage vary depending on the load. With an electromagnetic (solenoid) chime the voltage will drop to near 16 volts when the button is pushed.

However the no-load voltage could damage a lighted pushbutton or an electronic chime.

I remember when Rittenhouse door chime contractor packs with two buttons were $8.
