26.6 Frequency Response Calibration
Frequency Response is calibrated during assembly and the trim capacitors are sealed at the factory and seldom
require adjustment.
Important: If there is significant overshoot you will need to open the unit and remove the sealing glue to be able
to adjust the trim capacitors to get a square wave without overshoot.
With the power OFF use a Philips screwdriver to undo the two screws on the bottom of the Cleverscope case
assembly. Remove the lid, and power up with the lid still off. Leave it powered for 30 minutes to stabilise
operating temperature.
