Safety and Operating Guidelines:
Ensure proper training for personnel handling ATH transducers to prevent electrical hazards.
Switch off and isolate the test circuit before making any connections.
Use safety-rated cables with proper insulation for all connections to avoid human contact.
Ground the ATH output (LO terminal) correctly to prevent errors or hazards.
Verify that maximum input-to-output isolation ratings are not exceeded.
Protect circuits with over-current protection devices.
Do not apply mechanical stress to ATH terminals during installation.
Operate the ATH transducer only with the case closed.
Store and use the transducer in clean and dry environments, free from explosion risks.
