Figure 3.3: SafeGround
A button on each channel toolbar in the software allows to control the Safe Ground
state between differential and single ended
When Safe Ground is enabled for a channel, the input is switched to single ended
and the ground current of that input is real time monitored. When the ground
current becomes too high (<500 mA), the ground connection is immediately (<100
ns) opened, protecting the input against short circuits to ground. Also a warning
dialog is shown:
Figure 3.4: SafeGround warning
Once the short circuit is removed, Safe Ground can be enabled again.
Safe Ground protects your scope, your computer and your circuit under test against
accidental wrong ground connections. The Safe Ground protected ground feature
is optionally available for the Handyscope HS6 DIFF.
3.1.2 Differential attenuators
To increase the input range of the Handyscope HS6 DIFF, it comes with a differ-
ential 1:10 attenuator for each channel. This differential attenuator is specially de-
signed to be used with the Handyscope HS6 DIFF.
