1) Open the battery door, remove the battery box;
2) Insert 6 x AAA 1.5V alkaline batteries into the battery box, observing the correct polarity. Then put back the battery
box according to the marking direction.
The following picture illustrates transmitter installation:
Please pay attention to the following issues in installation:
1) The distance between transmitter bottom and highest water surface must be 0.5m (1.64ft) or more.
2) The maximum depth the unit can measure is 15m (49.2ft).
3) Observe the balance bubble on the sensor to ensure it is installed at a level horizontal position.

1) The sensor is not installed at a level horizontal position.
2) The sensor is too close to the Tank wall.
3) There are solid objects in the tank.
4) The transmitter bottom is dipped in the water (or other liquids in tank)
Note: Even though it works fine in occasional water splash or dew, this product is not completely water proof in heavy
rain. It is highly recommended that a cover be installed above the unit.
First, insert the batteries into the wireless solar transmitter (6 x AAA) and then insert batteries immediately into the LCD
display base unit (2 x AA). Once the batteries are in place, all segments of the LCD will light up briefly.

increase or decrease air gap. Long press or key to increase or decrease air gap at greater step.
Press the key to exit depth setting
NOTE: Air Gap (see H1 in sketch of 2.2) is defined as the distance from the bottom of the tank transmitter to the
maximum fluid level of tank. The range is: 0.5M(min) - 15.0M(max) or 1.64" (min)-49.2" (max).
If there’s no key operation in depth setting mode for longer than 15s the unit will switch to normal display mode
automatically. (There will be measurement errors if the tank depth and air gap are not set correctly).
In normal display mode press key for 3 seconds to enter SET mode (Figure 10).
HOUR: Hour value will flash. Press or key to increase or decrease hour value. When hour value
is set press key to set minute value (Figure 11).

Inspect power linePower supply is not well connected.Level meter does not work.
1. Inspect power line
2. Inspect the wiring and connect it
again.
3. Maintain it in the factory.
1. Power supply is not well connected.
2. Wiring between LCD and main
board falls off or comes loose.
3. The LCD is damaged.
Level meter does not display data.
1. Replace the level meter with a level
meter with greater measuring range.
2. The meter will restore the normal
measurement automatically after the
measured medium gets back to calm.
3. Check surrounding environment
and realize good electromagnetic
shielding. Do not share one power
supply with frequency converter and
motor, and make it grounded reliably.
4. Reinstall probe and make it
perpendicular to liquid surface.
5. Select an appropriate position for
installation and prevent an interfering
object.
6. Raise the installation position of
probe.
7. Check whether the medium is
powder. If so, consult the
manufacturer.
1. The measured area is beyond the
measuring range of level meter.
2. The measured medium has strong
disturbance, vibration or heavy dust.
3. There are strong interference
sources around such as frequency
converter and motor.
4. The probe is not aligned to the
measured surface.
5. There are redundant objects in the
measured space, such as support
rodsand feed openings.
6. The liquid level is in a blind area.
7. The measured medium is soft
powder or there is foam on liquid
surface.
Level meter works but there is no
change of trumpet icon on ( ) the
LC,which means that the system
is in a loststate.
