Attenuation ratio switch
Sets the attenuation of the probe to 100:1 or 1000:1. The setting 1000:1 provides
a maximum voltage range of up to 1.4 kV (peak). The setting 100:1 works with
measurement voltages up to 140 V (peak) and is characterized by less noise.
The selected attenuation does not influence the allowed working voltage, mea-
surement category, and the usable common mode range. Thus, setting the
attenuation does neither cause a hazardous situation nor a measurement error
due to inadmissible common mode voltages.
Power input
The supplied voltage must be less than 12
V and greater than 4.4
V, otherwise
the probe could be damaged or cannot be operated properly. Use the USB power
cord to connect the probe to an unused USB port of the oscilloscope or another
USB device, e.g. USB hub. Alternatively, batteries can be used to power the
probe.
Power switch
Switches the probe on or off.
If you use batteries, make sure to switch the probe off after use to extend the life-
time of the batteries.
Offset adjustment
The rotary knob removes unwanted offset voltages of the probe or the measure-
ment object from the measurement signal.

Overrange indicator
The overrange indicator lights red if the voltage of the differential input signal
exceeds the dynamic range limit of the probe. In this case, the signal on the
probe output may not accurately represent the signal on the probe input. The
overrange indicator does not detect overranges of common-mode voltages at the
probe inputs.
