1. INTRODUCTION
MT222 is a sensor for sensing AC High Voltage. It provides electric
engineering personnel, power engineering personnel, firefighting
personnel and instrument equipment workers with prominent warning
when approaching high voltage and for taking necessary safety action,
preventing illusion and misjudgment which could lead to electric shock to
person.
When a person wearing MT222 is approaching high voltage source or
equipment, the sensor will detect automatically and buzzer will generate a
"BeBe" sound for warning and LED will flash to remind operators that the
user is approaching a high voltage sauce and special attention shall be
given to the safety of operations.
