Fully Isolated Channel Design for Safe Measurements (models 2515/2516 only)
Models 2515 and 2516 offer two CAT III 600 V
input channels for floating measurements and
feature an electrically isolated circuit design between inputs and the digital acquisition circuit.
Isolating the ground references eliminate ground
loops and help reduce channel noise and crosstalk.
Input Signal and Float Voltage Safety Ratings
Model 2511 / 2512 2515 / 2516
Maximum signal input safety rating with included probe 300 Vrms CAT II 1000 Vrms CAT II, 600 Vrms CAT III
Maximum signal input safety rating without probe 300 Vrms CAT II 300 Vrms CAT II
Maximum reference floating safety rating 30 Vrms 1000 Vrms CAT II, 600 Vrms CAT III
All 2510 Series models come standard with high
bandwidth, safety certified passive probes (one per
channel) to help you get the most out of your
scope.
Safety Rated High Bandwidth
Oscilloscope Probes Floating and Differential Measurements
Many industrial applications such as power electronics require measurements of high voltages and currents
that are not referenced to ground. This poses an issue with traditional line-powered oscilloscopes, which
typically have signal common connected to the chassis of the oscilloscope. This means all measurements
must be made relative to earth ground, preventing users from making differential measurements where none
of the test points are referenced to ground.
As a workaround, some people choose to float an oscilloscope by removing the connection between the
instrument's chassis and power line ground. Floating a scope is not recommended as it can put the user
at a safety risk. Parasitic capacitance is also induced in the measurement which can cause ringing and
invalidate the measurement. The 2510 Series allows engineers and technicians to make accurate and safe
measurements when the signal reference is floating.
