related to the phase status, but the correspondence to the indication for
L1 (line) and N (neutral) might be incorrect. In case an asymmetric
mains plug is used, lines L1 and N have to be changed inside the plug
of the power cable.
(6) L1/N selector switch
Provided that the HM605-2 is correctly connected to the mains power
outlet (point

is lit after power-on. The EMC signal immediately
will be available at output jack “Test Receiver”
(11)
. By pushing button
(6)
the signal source toggles to line N, which is indicated by a LED

lit.
(8) PE selector switch
After setting HM6050-1 to operation (power on) the protective ground
simulation circuit is bypassed by default. After pushing button “PE”
(8)
the direct grounding of the protective earth line (according to VDE 0877
Part 1/03.89) will be replaced by a protective ground simulation circuit
(according to VDE 0877 Part 1/03.989 (89 (50 µH II 50
to ground)).
(10) Transient Limiter selector switch
After turn-on the transient limiter circuit is enabled by default, to protect
the attached Test Receiver’s or Spectrum Analyzer’s input circuitry
from high transient voltages. After pushing button
(10)
the transient
limiter circuit will be bypassed. A blinking red LED
(12)
indicates this
operating status.
(11) Test Receiver (test signal output)
The output impedance Z of the HM6050-2’s test signal output is 50 .
The shielding connection of the BNC jack is connected to the housing
and thus to ground. A two plug broadband BNC cable is used to attach
the HM6050-2 to a Test Receiver or Spectrum Analyzer. The built-in
transient limiter is enabled by default. Pushing button
(10)
provides
deactivation; LED
(12)
indicates this status by blinking.
(13) RM - LED
In remote control mode
„RM“ LED
is lit.
Attention!
Because of their test principles Test Receivers and Spectrum
Analyzers (i.e. HM5012/14) are extremely sensitive at their input
circuitry. To protect the input circuits from damage by high vol-
tage transients, it is highly recommended to use the equipment
with the transient limiter enabled (red LED off)! Due to switching
the DUT on and off, transients might arise, that possibly can
damage the input circuit of the Spectrum Analyzer or Test Recei-
ver. Damages of the input circuitry resulting from transient
voltages are not covered by HAMEG’s warranty.
