Hi Simon, depending on the software version you are using the probe menu should already contain 2 x 2000 amp probe settings, 2000a/200 mode and 2000a/2000a mode. To download the latest version of PicoScope go to https://www.picoauto.com/software-picosc ... otive.html
With the new software installed these clamps will be preloaded into your channel options automotive probe menu ready for selection.
You could also use the custom probes feature under the TOOLS menu to install the clamp but to save time I have attached both probes here.
Save these attached files to your desktop, open PicoScope, select TOOLS-CUSTOM PROBES-then click on IMPORT. Locate the files attached here on your desktop, then click OPEN. This will load the new custom probes into your custom probe Library. Thereafter you can click on you channel options button and select the probe setting from the Library. I hope this helps?
