Can you update your software to version 5.14.4. THis is the latest version available.
Once you have done this, confirm the new version by running the software and selecting Help|About. Check that the version is correct and all the calibration information is available.
Let me know how you get on.
Best regards,
Michael

Cheers for the advice. Have installed latest version but still refuses to measure anything when set at +- 2V or below, and at +- 5V or 10V the scale is too large to be accurate?
Can you try using the ADC100 adapter that came with the unit. Remember to read the help file regarding this.
When you are using this adaptor you will need to tell the computer so that it recognises that it is there. To do this you need to insert the following patch into the win.ini file:
[ADC100]
UseAdapter=Yes
You should insert the patch on a new line and exactly as written above. When you have done this, save the file and exit. The Picoscope software should now recognise the adaptor and report "Use Adapter" in Help | About. The ADC-100 should also now be functioning normally.
This should help the units reference voltages.
If the problem persists, please contact us again.
