Operation with a Teledyne LeCroy Oscilloscope   

The probe can be controlled through the Vertical Setup dialog for the channel to which the probe is 
connected. 

Turning the 

VOLTS/DIV

 knob will control the oscilloscope’s scale factor to give full dynamic range from 

20 mA/div to 50 A/div. 

The CP030 probe dialog (a tab behind the channel setup dialog) allows for the selection of the probe’s 
coupling (

DC, Grounded 

or 

AC

), 

AUTO ZERO, DEGAUSS PROBE

 and 

Probe BWL

 functions, limiting the 

system bandwidth to 20 MHz or maximum bandwidth (BWL Off). 

Bandwidth Limit   

The CP030 is capable of switching the bandwidth from 

Full 

(maximum bandwidth) to 

20 MHz 

by 

selecting the bandwidth adjustment in the channel menu. 

Auto Zero 

The CP031 incorporates an Auto Zero function to remove the DC offset from the current probe. Auto 
Zero must be invoked by the user. After several minutes of warm-up, or when the probe is exposed to a 
large shift in ambient temperature, some DC offset drift may occur. To initiate an Auto Zero cycle, touch 
the CP031 tab of the (Channel) Vertical Setup dialog, then touch 

AUTO ZERO

. 

Degauss Probe   

If the probe has been magnetized by external magnetic field or by excessive input, the core can be 
demagnetized by opening the CP030 dialog and touching 

DEGAUSS PROBE

. The demagnetizing process 

takes about 5 seconds and should always be performed before taking a measurement. 

Without clamping the probe around a conductor, slide the opening lever to close and lock the probe and 
press the 

DEGAUSS

 

PROBE 

button. 

An Auto Zero is automatically performed as part of the degauss cycle.
