3 Field of application
•Transmission of analog signals during EMC-tests
•Transmission of analog signals over long distances wit out voltage
loss (up to 100m or more, depending on timing requirements)
•Handle ground potential problems
T e U8/12-1M as integrated filters enabling EMS and EMI testing. T ere is
no need for external filtering.
4 Maintenance
Rec arge batteries after use wit t e enclosed c arger. To prevent a lazy
battery effect, disc arge t e devices every 5 times completely by using t e
automatic switc off (Leave t e system on, until it turns off automatically).
Afterwards, c arge t e devices as usual.
T e devices ave to be turned off before connecting to t e c arger. If t is
is disregarded, t e system mig t get damaged!
Fig. 4.1 s ows t e pinning of t e c arge connector. C argers ave to be
connected to pin 2 (+) and pin 4 (GND). An external supply (8-10V, 0.5A)
can be connected to pin 3 (+) and pin 4 (GND). se only power supplies
which are certified by mk-messtechnik.
T e included c argers are not meant to power t e transceivers during
operation. T e transceiver outside t e s ielded room can be run wit an
external power supply (optional). T e internal transceiver can be run wit
an external battery, if needed (optional). Do not use t e external power
supply or c arger to power t e transceiver inside t e s ielded room w ile
EMI-tests are running. T is mig t damage t e transceiver!
Due to self-disc arge issues wit NiMH batteries, rec arge batteries before
use, if t e system as not been used for a longer time.
