POWER ON
Power on the instrument shows the boot symbol.
After a few seconds, the level or distance value is displayed.
The
▲
symbol flashes on the left of the screen, indicating that
an echo is received.At the same time, the symbol
▲
point to
the variable abbreviation (L, D, T) on the panel to indicate the
corresponding current display value.
When the meter is powered on, reset or exited from the
parameter setting status, the level or distance value is first
displayed, which is determined by the currently selected
measurement variable (selected in the parameter setting).
KEYS
Press the SEL
，
the level meter can switch to select the
display level value, distance value, temperature value.
Press the button should be released immediately.
In running state, INC/MOV key is invalid.
Press the SEL, MOV key together and instantly release
the key to enter or exit the parameter setting state.
RESET
Press SEL and MOV at the same time and hold for
more than 4s can reset the meter and enter into the parameter
setting state, press the SEL, MOV key at the same time and
instantly release to exit.
DISPLAY AND CURRENT OUTPUT
Level and distance unit is the meter(foot can be set in the
inner setting), the temperature is °C.
The distance value is directly obtained by the level meter,
level value is the installation height value to subtract the
measured distance value obtained. Therefore, the distance
value must be accurate, the installation height must be
accurately set.
Ambient temperature affects the accuracy of sound
velocity, temperature values should be displayed correctly.
Without HART function, the current output corresponds to
the measured variable (level or distance) selected in the
parameter. With HART function, the current corresponds to
the level only.
Installation height must be accurate and should be
greater than or equal to the distance measurement value.If it
