7.6 STOPPRECISIONINAUTOMODE
The function described in this paragraph only concerns those
operators who want to obtain the maximum dispensing stop
precision in AUTO mode. If a slight excess of the preset value
(a few hundredths of litres) does not cause any problem, the
present paragraph can be ignored.
The ETER, in AUTO mode, allows the user to obtain a high
precision stop, thus dispensing exactly the preset amount
without exceeding the PRESET value.
To guarantee this hgh stop precision, especially when the unit
operates at the maximum allowed f low-rates, the valve does
not close when the PRESET value is reached, but when the
dispensed amount is lower than the PRESET value by a few
Unit hundredths. To guarantee the dispensing stop precision,
this pre-stop value must not be fixed, but strictly dependent on
the flow-rate used. To allow the anager to obtain the highest
stop precision, the unit has been equipped with a Stop Precision
Factor (Precision Stop) called PS factor. The anager, during the
ETER customization, can select a PS Factor ranging between
ZERO and FIVE. By selecting PS = 0 a pre-closing equal to ZERO
is set; by selecting PS = 5 the MAXIMUM pre-closing is set.
The higher the flow rate, the higher the selected PS value must
be. Selecting a too high PS value, the dispensed amount may be
lower than the preset value by some hundredts of a litre.
When the ETER displays:
Blinking
Press AUTO to increase the PS Factor by one unit.
Blinking
Keep on pressing AUTO until the desired PS factor value is
displayed.
Blinking
Press AUTO and keep it pressed to access the next activity.
Press RESET to exit the customization menu.
7.7 CALIBRATING
The ETER is equipped with a liter-counter high precision oval
gears, factory pre-calibrated.
Why calibrate?
If the ETER is used:
with fluids having a viscosity close to the limits of the
allowed range (such as low viscosity antifreeze fluids or high
viscosity oils for gear boxes)
in extreme flow-rate conditions (close to the min. and max.
values of the allowed range) it may be necessary to carry out
an on-site calibration.
How to
calibrate
The ETER allows the user to carry out a fast and accurate
electronic calibration by modifying the Calibration factor (K
Factor).
At delivery, all ETERS are given the same calibration factor:
K Factor = 1,000
This calibration factor guarantees the best accuracy in the
following conditions:
Fluid: motor oil type 10W 30.
Temperature: 20°C.
Flow-rate: 10 liter/min.
The calibration can be done either as:
An on-site calibration, by dispensing into a calibrated
container;
A direct modification of the calibration factor.
When the ETER displays:
On-site
calibration by
dispensing into
a calibrated
container
Blinking
press the AUTO key; it is possible to start the calibration by
dispensing the fluid into a calibrated container.
During dispensing the ETER displays:
Batch total dispensed
Blinking
The dispensing operation may be freely interrupted and
resumed.
The Calibration dispensing is finished when the fluid level
reaches the graduated area in the calibrated container.
Blinking
Indicated value
To obtain a correct ETER calibration, it is necessary to use
an accurate sample container having a capacity not less than
5 liters.
Completely purge all air from the unit (see par. 5.7) before
performing the calibration.
Perform the calibration dispensing at a steady flow-rate, by
pulling the trigger fully down and keeping it in open position until
the container is full.
During the final dispensing phase, do not reduce the flow-rate
to reach the graduated area in the calibrated container.
The correct technique to be adopted at the final stages of the
filling operations into the calibrated container is "small topping-
ups"; this is achieved by rapidly pulling the
ETER trigger fully down and then releasing it very quickly.
Press AUTO to confirm the end of the calibration dispensing.

After dispensing, wait for a few minutes to allow any possible
air bubble to be bled from the sample container. Read the Real
value only at the end of this phase as the level may decrease in
the container.
Do not wait for more than 15 minutes as the METER will exit
the menu and it will be no longer possible to complete the
calibration procedure.
The ETER is ready to accept the modification of the indicated
value to be matched with the real value.
Press the “10” key to increase the indicated value.
Press the “0.1” key to decrease the indicated value.
Each time a key is pressed, the last digit on the right is modified
by one unit.

After a few seconds the ETER automatically exits the
customization mode and starts using the new Calibration Factor.
One dispensing operation is enough to carry out the on-site
calibration of the liter-counter.
If you wish to verify the result of this calibration, perform a
normal dispensing in the same sample calibrated container,
without re-entering the calibration function in Customization
menu.
Direct
modification of
the calibration
factor
The direct correction of the Calibration Factor is useful when:
the K Factor in use must be corrected by a known
percentage;
a K Factor already known must be added.
When the ETER displays:
Blinking
press the AUTO key, release it and press the AUTO key again.
The ETER displays:
Blinking
The ETER is ready to accept the direct modification of the K
Factor.

Press the “0.1 “ key to decrease the indicated value.
Each time a key is pressed, the last digit on the right is modified
by one unit.
By keeping the keys pressed, the value changes, slowly at first
and then rapidly.
Press the AUTO key to confirm that the correction of the
indicated value is over.
The ETER stores the new Calibration Factor (K Factor) and
displays:

After a few seconds the ETER automatically exits the
customization mode and starts using the new Calibration Factor.
8 MAINTENANCEOFTHEMETER
The only routine maintenance operations required by the
ETER are:
baery replacement;
filter cleaning.
These activities can be easily performed using standard tools.
Any other extraordinary maintenance operation must be
carried out by an authorized Service Centre.
8.1 BATTERYREPLACEMENT
The ETER continuously controls the battery charging state. As
soon as the charge decreases below a given level, the ETER
displays:
“bAtt" message
Blinking
warning the Operator about the need to replace the batteries.
As soon as the message “bAtt” is displayed, dispensing in
“AUTO” mode is immediately inhibited and it is no longer
possible to lock the trigger in open position. This prevents the
unit from dispensing continuously in AUTO mode even if the
PRESET value has been reached, due to an insufficient battery
charge.
Even when the message “bAtt” is displayed, it is still possible
to perform dispensing in MANUAL mode.
Although it is possible to carry out tens of dispensing operations
in ANUAL mode, even after the message “bAtt” is displayed,
the battery must be replaced as soon as possible to resume
the full operation of the METER and to prevent the LCD image
quality from deteriorating, thus causing metering errors. When
the message “bAtt” blinks, the TOTAL is constantly updated,
although no longer displayed.
To replace the baery:
1. Using a small screwdriver (PH cross head, bit no. 1) completely
slacken the four screws of the baery compartment cover
and remove it.
2. remove the flat baeries;
3. install the new baeries;
4. replace the cover and tighten the four screws.
WARNING: press the RESET key after battery replacement.
The ETER will restart automatically, carrying out a short SELF-
TEST:
complete lighting of the LCD;
complete power-off of the LCD;
display of the electronic board serial number;
normal operation mode resumed.
Battery replacement does not cause any data loss. The METER
customization, previously set, remains operational at the next
re-starting.
8.2 CLEANINGTHEFILTER
The ETER is equipped with a removable filter for inspection
and cleaning, installed inside the swivel.
Filter clogging can strongly reduce the maximum flow-rate
supplied by the ETER.
Regularly clean the filter and check it each time a reduction in
flow-rate is detected.
To reduce the frequency of filter cleaning operations, the ETER
dispensing system should be equipped with suitable line filters.
To clean or replace the filter:
1. Release the line pressure and dismount the ETER in
compliance with the instructions given in paragraph 5.2.
2. Unscrew the 1/2” nut and remove the filtering disk.
3. Properly clean the filter or use a new filter (see Spare parts
list in paragraph 10.3).
4. Place the filter again, paying aention to components’
positioning.
Do not use filters which have been damaged during improper
dismounting or cleaning operations.
Always reposition the filter with the utmost care.
Only a filter in good condition and correctly installed can
guarantee the good operation of the METER, thus preventing
any dust or foreign bodies from locking or damaging the
METER valve.
5. Reassemble the ETER according to the instructions given
in paragraph 5.6.
6. Fix the swivel again and tighten at 20 Nm.

4 GETTING TO KNOW THE METER
The ETER is a dispensing nozzle for oils and other fluids, to
be installed as a final shutoff device at the end of pressurized
flexible hoses.
Besides guaranteeing an exact measurement and display of the
fluid amount dispensed, when used as a normal nozzle.
The METER also allows the user to PRESELECT the quantity
to be supplied and automatically stops dispensing when the
preset amount has been reached.
The ETER integrates:
"(#%&!'$
A. An ergonomic handle.
B.
A swivel, with a rubber cover, which allows the user to rotate the handle
independently from the connected flexible hose.
C.
A flow control valve, activated by a trigger, which is equipped with a protection
against accidental starts.
D.
A meter with oval gears, controlled by an electronic board and equipped with a
battery-powered microprocessor.
E.
A large liquid-crystal display, integrated in the 5-key keypad, for the communication

and houses the filter.
The large filtering surface guarantees a reduced pressure loss.
The rubber cover of the swivel
During installation the swivel may be equipped with a rubber
cover to prevent the swivel itself or the metal end of the flexible
hose from damaging the vehicle body.
This cover is available in different colours, which can be used as
a "colour code" to identify the dispensed product easily.

The dripless valve can be rotated by 240°
4.2 MANUALANDAUTOOPERATION
The ETER is a PRESETTABLE dispensing nozzle which can be
used in two operating modes:
MANUAL Mode In ANUAL mode, dispensing starts as soon as the Operator
operates the trigger.
The only preliminary operation to be carried out by means of
the ETER keys is the possible reseing (RESET) of the value
previously indicated on the Batch total.
The operator must check the dispensing operation personally
and stop it by releasing the trigger when the desired amount is
reached.
The ETER has been designed to ensure maximum safety during
use an avoid oil spillage due to an improper use or operator's
carelessness.
In particolar the ETER does not allow the valve to be locked in
open position during MANUAL mode. This avoids a continuous
dispensing, should the operator be absent or has not preset an
automatic stop value (AUTO mode).
AUTO Mode To dispense using the PRESELECTION option, before starting
dispensing the operator must:
Select the desired amount by means of the ETER keys as
explained in paragraph 6.2.
Confirm the selected value thus entering the AUTO mode:
The ETER displays the AUTO message and is ready to
dispense automatically without requiring the presence of the
operator.
Start dispensing, by pulling the trigger and seing it to the
locked position.
The operator's presence is no longer needed and he can wait
until the ETER automatically stops once the selected amount
has been dispensed.
In any case the operator must attend to the METER while
dispensing in AUTO mode in order to avoid any oil spillage due
to external factors.
Carefully read the instructions given in paragraph 6.2 before
dispensing in AUTO mode.
The ETER allows the user to lock the trigger in open position
only when the display shows the message AUTO.
To lock the trigger in open position:
pull it completely;
then release it.
If the message AUTO blinks, automatic dispensing cannot
be started; if the trigger is completely pulled and afterwards
released, it does not remain locked in position, but it closes again
thus interrupting the dispensing operation.
The blinking message AUTO indicates that the selecting phase
of the desired value is still in progress, but the AUTO mode has
not yet been entered by confirming the displayed value.
The ETER automatically unlocks the trigger thus stopping the
dispensing when the predetermined value has been reached.
However, while dispensing in AUTO mode, it is possible to stop
dispensing manually before the desired value is reached by
unlocking the trigger.
To unlock the trigger and set it in closed position again:
pull it completely;
then release it.
When the dispensing has been manually stopped, as soon as
the AUTO message is displayed, it is possible to restart the
automatic operation as the trigger can still be locked in open
position.
The ETER automatically exits the AUTO mode after a given
period of time (TI E OUT) without dispensing.
5 INSTALLING THE METER
This paragraph describes the necessary operations to be
carried out when the METER is installed for the first time on a
new system or to replace an existing nozzle with the METER.
5.1 SYSTEMREQUIREMENTS
12
4
3
5
6
The ETER has been designed to be used as a component of
a centralized system for oil distribution and other industrial
fluids, which must bemanufactured and installed by specialized
personnel in compliance with the standards relevant to such a
pressurized system.
To explain the installation and maintenance operations relevant
to the ETER, refer to the following diagram which shows a
typical installation, as regards to the components located
directly upstream any “dispensing outlet” of the ETER.
1. Distribution system lines.
2. Shut-off valve.
3. Flexible hose for reel entry.
4. Reel.
5. Flexible hose.
6. Nozzle.
The presence of the shut-off valve in the system is necessary
to ensure a safe and correct installation and maintenance
of the ETER without requiring to make the whole system
unserviceable.
The structure and complexity of the system upstream the above-
mentioned shut-off valve (rigid or flexible feeding lines, pumps,
tanks, valves, etc.) as well as the possible presence of the flexible
hose reel can be freely chosen by the installer. In fact they do not
affect the maintenance operations of the ETER.
5.2 LINEPRESSURERELIEF
This operation is to be carried out when replacing a pre-existing
nozzle with the ETER nozzle or when dismounting the ETER
for maintenance purposes.
Failure to carry out the line pressure relief procedure may
cause damage to persons or things.
Close the shut-off valve. Otherwise stop the feeding pump
and make it unserviceable to avoid an accidental re-start
during maintenance operations.
Operate the valve of the nozzle to be replaced (or of the
ETER to be disassembled for maintenance purposes)
dispensing into a suitable container in order to release the
line pressure.
If a dripless valve is installed at the end of the nozzle, the
pressure inside the line will not drop to zero, but it may remain
around 0.2 - 0.5 bar, according to the dripless valve used.
Only for ETER dismounting: remove the rubber cover from
its coupling on the swivel and move it along the flexible hose
in order to gain an easy access to the swivel.
By means of two wrenches, unscrew the threaded end of the
flexible hose from the swivel.
Be careful to collect any oil leakage into a suitable container.
5.3 FLUSHINGTHELINES
Flushing the lines means to let a given amount of oil flow inside
them, so as to ensure a proper “ washing” of the whole system,
a correct cleaning and the absence of dirt, contaminated
material or processed waste inside the lines before installing
the nozzle.
The flushing operation must be carried out on all lines upstream
the nozzle and, in case the system is equipped with more than
one nozzle, flush the lines which supply the nozzles farthest away
from the supply pump, then continue with the nozzles situated
near the pump.
The flushing procedure depends on the type and features of
the system and must be carried out by trained and qualified
personnel in compliance with the procedures set down by the
installer.
This operation is absolutely necessary with NEW
INSTALLATIONS or if the lines used are contaminated.
Consequently it may not be necessary to carry out this
procedure when replacing a nozzle already in use.
5.4 PRELIMINARYCHECKSONTHEMETER
ake sure that the threaded end fied on the flexible hose is
suitable for the swivel of the ETER equipped with: Female
thread 1/2” BSP or Female thread 1/2” NPT.
Filter
Check that the ETER nozzle to be installed is complete and
in good condition, making sure that the filter is clean and
correctly installed (see paragraph 8.2).
The METER filter, characterized by a large filtering surface,
has been designed to guarantee a correct filtering and a low
pressure loss.
To remove and re-install the filter, refer to paragraph 8.2.
The absence or improper installation of the filter may block the
METER valve o the liter-counter if dirt is present in the tubes.
This situation may occur especially during new installations. To
solve these problems, consult a qualified Service Centre.
 MOUNTINGTHEEXTENSIONONTHEMETER
D
E
B
C
A
Three different types of extensions can be installed on the
ETER nozzle:
SWIVELLING extension;
RIGID extension;
FLEXIBLE extension;
All of them are equipped with an automatic dripless valve.
All extensions on the nozzle side are equipped with a rigid
ending part (external Ø 12 mm, 3/8"G nut) suitable for a quick
connection to the ETER without using any sealant.
Remove the plug from outlet A (3/8”G).
ake sure that gasket B on the swivel is correctly seated.
Lubricate the gasket and its seat.
Tighten end D on ETER by means of two wrenches; while
the first one on outlet A locks the ETER, the second one
tightens nut C on end D. Before locking nut C orientate valve
E.
An improper tightening of the extension may cause it to
become loose thus endangering persons or things. Tighten the
ring nut with a torque wrench setting of 3.5 Kgm
5.6 MOUNTINGTHEMETER
Fit the rubber cover of the swivel into the flexible hose, in
the direction indicated in figure, making it slide over the male
thread of the hose.
Apply a thread sealant to the male thread of the hose.
Tighten the swivel completely by means of two wrenches.
Slide the rubber cover towards the valve until it fits into the
seat, located on the swivel.
5.7 AIRPURGINGFROMTHELINES
After the installation of the nozzle, a certain quantity of air will
be inevitably present both inside the flexible hose downline the
shut-off valve and in the other system lines. To purge the air
and guarantee a steady flow and a correct calculation of the
amount dispensed, two operators should proceed as follows:
With the shut-off valve still closed, insert the ETER
extension into the opening of a container of suitable capacity,
to avoid spraying or spillage which may occur during the initial
irregular flow.
While the first operator acts on the ETER trigger, the
second must open the shut-off valve; when the flow starts
being steady, the second operator shall set the valve to the
fully open position.
Continue line purging while keeping the ETER valve
completely open, till reaching a steady flow. At this point
release the trigger thus stopping dispensing.
5.8 CHECKINGTHEFLOWRATE
Once carried out the installation and purging operations, it is
advisable to check the dispensing flow-rate which must comply
with the range indicated in paragraph 10.1, to ensure a correct
operation of the valve.
The METER allows the user to check easily and directly the
dispensing flow-rate:
During the operation in ANUAL mode, press and keep
pressed the AUTO key.
The ETER will display the current flow-rate in units per minute.
Batch total dispensed
Current flow-rate
If the flow-rate exceeds the range limits, adjust the system
components (pumps or balancing valves) to comply with them.
6 USING THE METER
The ETER has been designed for professional use and
must be utilized by adult personnel properly trained for the
intended purpose.
The ETER must not be used outside the operating ranges
(see Technical Data in paragraph 10.1) or for fluids other than
lubricants and anti-freeze mixtures.
Do not tamper with or modify the ETER.
Regularly check the good condition of the ETER.
The ETER dispenses high-pressure fluids; do not point the
nozzle to any part of the body.
Use the personal protection equipment recommended by the
national standards relevant to the dispensed products.
Do not carry out any maintenance operation on the ETER
without previously relieving the pressure from the system
lines.
The ETER is designed for indoor use only.
Is used outdoors, make sure it will not be exposed to rain, snow
or direct sunrays.
In case of manual dripless valve, after a daily use it is important
to discharge the overpressure between the chamber (1) and
the manual valve (2) of the spout. Carry out this operation with
the pump switched off. Then unscrew the valve (2). During this
discharging operation, do NOT push the trigger (3).
