8.1. Oscilloscope
Only if another instructions are provided, are all technical specifications applicable to the probe with the 10X attenuation
switch setting and the PeakTech
®
1220 digital oscilloscope. In order to be up to these specifications, the oscilloscope
should meet the following requirement.
 The instrument should operate continuously for more than 30 minutes under the specified operating temperature.
 If the operating temperature range of variation is up to or larger than 5 Celsius degrees, the system function menu must
be opened to make the system perform a “self- calibration” procedure.
Except those specifications marked with the word Typical, all specifications can be up to.
