4.6 Details on EMC

When the device is exposed to electromagnetic emissions the lower limits of the ranges in table 4.2 are
increased by 5 dB. Within these changed ranges the error limits according to IEC 61672-1:2003 are main-
tained. The level linearity range changes to 40
emissions. There will be no performance loss in the device after electrostatic discharges (touch discharge
up tp 4 kV and air discharge up to 8 kV).

4.7 Effect of environmental conditions

In order to avoid the effect of sound reflections from the body of the operator interfering with the measure-
ment, Tango_Plus should be located as far as possible from the body. Thus, when actually performing the
measurement, the operator should place himself at a distance behind the tripod-mounted meter, or extend
the hand-held meter as far from the body as is comfortable.
NOTICE!
4.7.1 Mains frequency and high-frequency fields
Tango_Plus complies with IEC 61672-1:2003 with respect to interference immunity to mains frequency and
high-frequency fields. The interference immunity to mains frequency and high-frequency fields is highest
when the device is running on batteries/rechargeables without USB cable connected.
If Tango_Plus is connected to a PC and measuring high-frequency emissions are highest. Additionally, the
interference immunity to mains frequency and high-frequency fields is lowest in this configuration (alignment
see fig. 4.4). The next lowest emission level is reached in the same configuration, but in STOP-Mode.
In compliance with paragraph 6.6.9 of IEC 61672-1:2003 Tango_Plus is not appropriate to measure levels
lower than 74 dB for an electric field strength exceeding 10 V/m.
