14.3 POOR INSULATION AGAINST THE BODY OF THE CELL:
Problem: excessive zero-drift, notable instability of the zero, insulation below one
Mohm.
Causes:
water penetration, persistent high humidity in the cell, electrical discharges
between the electrical circuit and the body of the cell.
Solution:
if the cause is the penetration of water, it is recommended to bake the cell in
an oven at 85°C for at least 10 days, hoping that no conductive residue will remain; if
the causes are electrical discharges with carbon residues the repair is more expensive than
the replacement by a new cell.
14.4 DAMAGED ELECTRICAL CONNECTIONS:
Problem: a highly fluctuating output signal (especially if cable or connectors are
moved) or no signal at all.
Causes:
electrical connection cable or connector mechanically damaged by vibrations,
shocks, bumping against sharp edges or by long term dynamic movements.
Solutions: cable or connector is to be substituted. Cable should be applied in proper
connection channel as well as mechanically fixed to the machine in order to reduce
vibration effects.
14.5 BUILT-IN DAMAGED ELECTRONICS:
Problem:
no output signal.
Causes:
overvoltage, short circuit or misconnections.
Solutions: repair might be possible depending on damage type.
