Burn out: the instrument shows the burn out
condition as an underrange condition for 4-20
mA, 1-5 V and 2-10 V input types.
It shows the burn out condition as an underrange
or an overrange  condition (selectable by
soldering jumper) for 0-60 mV and 12-60 mV
input types. No indication are available for 0-20
mA, 0-5 V and 0-10 V input types.
