P5205 Instruction Manual 3
The P5205 has several features and accessories that make probing
and measurementa simpler task. Take a moment to familiarize
yourself with these items and their uses.
Differential Inputs. The inputs are rated to safely accept
a maximum of 1,000 VRMSCAT II between either
input and earth ground and a maximum difference of
1,300 V(DC + peak AC) bet ween the inputs.
NOTE. The input safety ratings are valid for both
attenuation range settings. However, for useful
measurements, the input should be kept to the
operating limitsof the selected attenuation range of
130 V up to 1,300 V (DC + peak AC).
Attenuation Range. In the raised positionthe range
button sets the attenuation to 500X. In the lowered
positionthe range button sets the attenuation to 50X.
Use the 500X position formeasurements up to a
maximum of 1,300V (DC + peak AC) differential.Use
the 50X positionfor better signal resolution on
connections below 130 V (DC + peak AC).
Overrange Indicator.The ove rrange indicator lights red
if the voltage of the input signal exceeds the linear
operating range of the probe. When this happens, the
signal on the probe output does not accurately represent
the signal on the probe input.
Audible Overrange. In the raised positionthe overrange
button sets the audible alarm to sound whenever the
overrange indicator lights.
Bandwidth Select. In the raised positionthe bandwidth
button setsthe full bandwidth (100 MHz minimum). In
the lowered positionthe bandwidth is restricted to
approximately5 MHz.
