is less than the distance measurement value, then the left two
symbols flashing at the same time,the level value and the
corresponding current value does not change, but the
distance value changes(If the PV is set as the distance value,
the current output changes).
If the level meter displays only the boot symbol for a long
time after power on, or if the SEL key is pressed, the
instrument level and distance measurement display 0.000
while the symbol do not flashing that the level meter fails to
work normally.

Parameters
Significance
Installation
height
The distance from the surface of the probe to the
bottom of the container;unit is m(ft can be choose
from the inner setting).
Full span
The 20mA output corresponding to the maximum
value of the PV.
Can also be programmed by the hart hand-held
programmer.
Zero span
The 4mA output corresponding to the minimum
value of the PV.
Can also be programmed by the hart hand-held
programmer.
PV select
Select the 4-20mA corresponding to the level or the
distance value.When the setting is HL99 the
current corresponding to the distance value. The
any other value the current corresponding to the
level value.(This parameter is not available with
