Field Verification Device
Amplifier Test
• Detector Current
• The current [A] and excitation frequency [Hz] are measured
• Analog Input
• Amplification and linearity is measured [div/V]
• Analog Output
• Offset and linearity is measured [mA]
• Inputs/Outputs
• The In- and Ouput function are tested as well as output frequency [Hz]
• Empty Pipe
Detector Test
• Coil Resistance
• Measures the resistance of the coils [Ohm]
• Electrode Impedance
• Measures the impedance of the 3 electrodes (measuring and empty pipe) in [Ohm]
• Isolation
• Measures the resistance of the coils against ground [Ohm]
