Channel-to-earth
Caution Do not connect the TB-12399 to signals or use for measurements within Measurement Categories II, III, or IV.
Attention Ne connectez pas le TB-12399 à des signaux et ne l'utilisez pas pour effectuer des mesures dans les catégories de mesure II, III ou IV.
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.
Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct
connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
