Safety Voltages
Connect only voltages that are within these limits.
V terminal to C terminal ........................................30 V max, Measurement Category I
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.
Caution
Do
not
connect the system to signals or use for measurements within Measurement
Categories II, III, or IV.
RF Safety Warning
This product complies with FCC radiation exposure limits set for uncontrolled equipment and meets the
