which type of screwdriver do I need?

Purchased the picoscope 2205A with two probes included. But when I want to calibrate a probe,
P6060, I am facing problems when I use an ordinary screwdriver and I do not want to ruin the probe.
Tried to find out which kind of tool I need but without success.
Can somebody tell me what kind of screwdriver I need?
Thanks.

Hi AnalogueMan,

There should have been a small tool included with the probes to allow you to do this.

If you have not received this, please e-mail support@picotech.com with your contact details or use a screwdriver with a small flat blade.

Regards,

Mea Culpa! I completely overlooked that little plastic bag with that small tool.
Must be my age, sorry
Thanks for your reply.

I suppose it can be overlooked - glad you found it!
