Safety Voltages
Connect only voltages that are within the following limits.
Isolation
Channel-to-channel None
Channel-to-earth ground
Continuous 60 VDC, Measurement
Category I
Withstand 1,000 Vrms, verified by a 5 s
dielectric withstand test
Measurement Category I is for measurements performed on
circuits not directly connected to the electrical distribution system
referred to as MAINS voltage. MAINS is a hazardous live
electrical supply system that powers equipment. This category is
for measurements of voltages from specially protected secondary
circuits. Such voltage measurements include signal levels, special
equipment, limited-energy parts of equipment, circuits powered
by regulated low-voltage sources, and electronics.
