1. INTRODUCTION
The ViewSonic Sensor is a battery operated ultrasonic liquid
level sensor that is capable of providing the user with instant
level indication at a glance. The ViewSonic Transmitter uses
ultrasonic (sound wave) technology to measure the distance
from the sensor face to the surface of the liquid in chemical
tank or sump, then back to sensor face; this is referred to as
(time of flight) As the liquid product inside the tank decreases
the distance that the senor measures increases accordingly.
The current level measurement can be viewed directly on the
LCD screen located on the sensor or via the remote display.
No wiring is required as the level data is wirelessly
transmitted to the remote display.
Gallons / Inches / %
After completion of programming the display calculates and
displays the amount of liquid remaining in your tank in
gallons, inches or as a percentage of the tank capacity. In
addition
Mounting
The ViewSonic sensor can be mounted directly on the top of
the tank, drum, tote and is suitable for use with any plastic
or metal tank up to 10'(3m) in height, including double
walled tanks.

Error Description To Rectify :
Check the transmitter is within range of the monitor.Try and relocate the
monitor to a position that is nearer a window,remember that the transmitter
communicates with the monitor by use of an FM signaland moving the
monitor plug from possible metalobstructions can improve the signal.
Check that there are no metal obstruction that may deflect the signal.
Ensure the monitor is not too close to,or obstructed by,other electrical
appliances.
Check positioning of the transmitter (ensure the transmitter is not too close to
the tank sides or internal obstructions).
Ensure that the transmitter is not too tightly attached to the tank.
Ensure that the tank is not overfilled i.e.thereisaminimumof 4 inches
free space between the transmitter and level.
Ensure the bottom of sensor is clean.
Check the tank height and ensure this information is correct on the monitor,
press the 6.andV keys together to view your tank configuration.If height is
incorrect,enter the setup mode by pressing SETUP for thre seconds,
press ENTER until you reach screen 5 and adjust the height using 6.andV keys.
Press ENTER to save.Press SETUP to exit Setup mode.Wait 3 hours for updated

will also light up and flash.The Audible sound can be turned off by pressing Enter
Alarm off :Turn alarm notification off .
Select AL ON/OFF using / .When the display shows your preferred setting press ENTER to save.
SETUP is now complete.Press SETUP to exit and progress to STEP 3.
On exiting Programming mode the monitor temporarily displays‘CALC’.
The Display must be in Pairing Mode (Lrn) mode which can
be entered in one of two ways:
A) Pressing SETUP after completing STEP 2 above
B) Disconnecting and reconnecting the power.The Pairing
mode (Lrn) the display shows ‘Lrn’ in the main screen area
(image 1).Pairing mode will last for approx 2 minutes during
which time you must‘match/pair’the sensor to the display.
The sensor LCD display should be facing in the same direction as the
LCD on the display as shown in image #4 base of the display.
Step 1 Position Sensor with Display-Hold for approx 5-10 Second
Step 2 If after 10 seconds syncing does not occur ( see Image 4)
Remove Sensor from Display for approx 5 seconds.-(Depending
on conditions this step may need to be repeated )
Step 3 Reposition Sensor with the Display (Image 3) Hold in place.
Once the units are connected the LCD bars on both the display and the
sensor with climb in sync while bars climb in sync, and audible beep is
emitted-This will indicate that the pairing is complete
Note: If at any stage during the Programming stage you exit SETUP mode , simply press and
hold the SETUP button for at least 3 seconds to begin again.

STEP 4 - INSTALLING theViewSonic Senor
After the pairing’ is complete the sensor will send level data continuously to the display for approximately
ten (10 minutes). Every time the display receives data from the sensor a audible clicking noise will sound
and the red LED light will flash on the ViewSonic Sensor
The pairing procedure can be confirmed by slowly lowering and raising the ViewSonic level sensor over a
flat surface and observing that the display reflects the changes. The ‘Quick-Click’ mode will stop after 10
minutes. The Viewsonic Sensor is now ready to mounted onto the tank/drum/ sump .
Note: Keep the Sensor Perpendicular to the surface being measured
Note: if after 10 minutes the sensor is not mounted , the display may show the error symbol or display
an incorrect reading.Itmaytake1-2 hours before the correct level data is shown on the display screen.
Tanks with pre-drilled hole
A 2" or 1 1/2" MNPT Bulkhead fitting is provide for threading
directly onto the tank.
Ensure the transmitter is vertical to the liquid on top of the tank.
Ensure the LCD Bar Graph is displaying current liquid level
