Measurement Accuracy and Speed

With U2000 Series USB power sensor , the range can be set either
automatically or manually. Use auto- ranging when you are not sure of the
power level you are about to measure.
The DC coupling of the U2004A USB power sensor input allows excellent
low frequency coverage. However, the presence of any DC voltages mixed
with the signal will have an adverse effect on the accuracy of the power
measurement, see
To prevent damage to your sensor, do not exceed the power levels specified in the
C A U T I O N
section
The U2004A USB Power Sensor is DC coupled. DC voltages in excess of the maximum
value (5 VDC) can damage the sensing diode.

Setting the Range

There are two manual settings, "LOWER" and "UPPER". The LOWER range
uses the more sensitive path and the UPPER range uses the attenuated
path in the U2000 Series USB power sensor (see
