PV is distance value (HL99)
Instrument inspection
1.Power supply should be correctly connected by the
identification . The voltage of Level meter is DC24V. External
power supply should have a 30mA current supply capability to
meet the startup current requirements.
2. Place the the level meter perpendicular to the wall, the
measured distance must not within the blind distance and
there should no obstacles. Power up the level meter.
3. The level meter first shows the boot symbol and then shows
the level value.
4. Press the SEL key, the meter can switch display distance
value, temperature value and level value.
5. Slowly move the level meter, the level or distance value
displayed on the meter should be changed accordingly.
When moving within close range (1m), speed should not exceed 0.1m / s.
There is a detection window inside the level meter. The target beyond
the detection window needs to have a judgment time of about 5s. The
measurement window below 10m is usually ± 0.5m, and the window
above 10m is ± 1.2m. Due to the detection window, the distance sudden
change from far to near about 1/2 of the distance , errors may be occur.
The sudden change of distance usually does not exist in the actual
measurement.
6. Press SEL and MOV keys simultaneously to enter the
program mode, set the installation height, full scale, zero scale
and other parameters
