Voltages
Connect only voltages that are within these limits.
Channel-to-GND....................................±30 V ma x,
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 elec tronics.
Caution Do not use this module for connection to signals or for measurements within
Measurement Categories II, III, or IV.
