Connecting a probe 3  Initial start-up

3.3 Connecting a probe
You can connect all probes recommended in chapter 2 
of this manual. In addition to the probe, you need a suit
-
able probe cable for the connection between the probe 
and the instrument. The probe connectors are located 
on the side of the instrument.
Probes with zeroing before coupling should 
not be coupled when the instrument is pow
-
ered on. The DMS Go+ tries to detect a zero 
point as long as the probe is coupled. 
Dual-type connectors
Most probe cables have a dual-type connector for both 
connection sockets on the instrument. To prevent a 
wrong connection, these connectors and the connection 
sockets on the probe and on the instrument are provid
-
ed with lugs.
– Connect the probe cable with the probe.
– Connect the probe cable with the probe connections 
on the side of the instrument.
Single-type connectors
If a probe is connected incorrectly, the con-
sequence would be a mismatching which 
may lead to considerable power losses or 
even to echo waveform distortions.
Both connector sockets are equally suitable (connected 
in parallel) for connecting single-element probes so that 
it does not matter which one of the two sockets is used.
When connecting a dual-element (TR) probe (having 
one transmitter or pulser element and one receiver ele
-
ment) or two probes (of which one is transmitting and 
the other one receiving), attention should be paid to the 
correct allocation of connecting cables (please see sym
