When measuring devices that are held in the hand during operation (e.g. electric drills),
the effect of the human hand is simulated by connecting to the "Artificial Hand" hand
simulation jack.
The hand simulation consists of the connection in series of a 220-pF-capacitor with a
510-
Ω
-resistor. The connection is located in the front panel of the R&S
ENV216.
If the housing of the equipment under test is made entirely of metal, the "Artificial
Hand" jack is connected to the housing the equipment under test.
If the housing is made from non-conductive material, metal foils are wound round the
handles and a 60 mm wide foil is wound round the point on the housing that can also
be gripped by the hand. All foils are connected together and with the "Artificial Hand"
jack.
The figure in chapter 3, section entitled "Sample measurement" on the following page
illustrates an example of how the foils are applied.
HF disturbers on the supply line of the R&S
ENV216 may lead to interference voltages
at the measurement output "RF Output".

Sample measurement
The figure shows the measurement setup for measuring the RFI voltage of a handheld
drill. In this example, the handheld drill is connected to three metal foils.
