Make sure the red VAR knob in the middle of the time base knob is all the way to the right. It should click into a detent. The UNCAL light to the left of the time base knob should then be unlit. You can't make time measurements when UNCAL is lit. How far off from 1KHz are you seeing? What are you using as the 1KHz reference? ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
