E-Meter Malfunction

My E-Meter is malfunctioning. The (V) Voltage appears to be normal. The (A) Amperage value always reads 508. Reset the unit and the (A) still reads 508. After reset the (Ah) rest and is now counting like a clock clicking up (.1) every second. Is thther anything else I should look at or is the unit toasted?
