Note: This is not a laboratory test instrument.  This is a purpose designed field test instrument that 
facilitates evaluation of  in-pavement loop characteristics including; inductance, DC Resistance, tuned 
frequency, ‘Q’ and insulation integrity.

EXTREME CARE REQUIRED WHEN using the insulation breakdown test function.  This is a 
controlled voltage ‘Megger’ test where typically 500V is applied to the output pins for a preset period 
(100milliseconds) while the microcomputer monitors the resistance to earth.
