Handling

  

CAUTION

•  Since the contact tips are very thin and sharp, handle them with 

care.

•  Avoid shock to the probe body. Do not bend or pull the cables 

excessively. Doing so may damage or disconnect the probe.

French

  

ATTENTION

•  Les pointes de contact étant très fines et pointues, manipulezles 

avec precaution.

•  Évitez les chocs sur le corps de la sonde. Ne pliez pas et ne tirez 

pas les câbles de manière excessive. Cela pourrait endommager 

ou déconnecter la sonde.

Adjustment Procedures

LF Compensation

LF needs to be adjusted when the probe is connected to the scope input 

the first time. LF compensation matches the probes cable capacitance to 

the oscilloscope input capacitance. This matching assures good amplitude 

accuracy from DC to upper bandwidth limit frequencies. A poorly compensated 

probe clearly influences the overall system performance (probe + scope) and 

introduces measurement errors resulting in inaccurate readings and distorted 

waveforms.

LF compensation is performed by connecting the probe to the COMP-output on 

the oscilloscope and adjust the LF compensation trimmer (see also the Figs. 

below.) optimum square wave response.
