Safety Notes
The MLT WESCO yarn meter has exclusively been designed for measuring the yarn infeed and the yarn tension in textile machines.
We would like to point out that we cannot be held liable for any damage or operating failures arising due to
an incorrect operation or improper device handling.
The metering roller must be able to rotate freely, without any obstruction.
The MLT WESCO contains electronic components which can be destroyed by electrostatic discharge when touched. Therefore, all measures to avoid such discharge, e.g. by means of touching
an earthed object (machine or earth contact of a plug, etc.), must be taken prior to opening the
device.
All contained components may only be replaced by original MEMMINGER-IRO spare parts.
NOTE!
Before using the MLT WESCO for the rst time, or if it hasn't been used for a while, the unit has to be
charged.

Function
The MLT WESCO yarn meter is a stand alone, electronic
hand-held measuring device for the measurement and
digital display of the machine speed, yarn consumption,
yarn tension and yarn speed in circular and at knitting
machines as well as in body, stocking, hosiery and sock
machines.
Application advantages of the MLT WESCO yarn
meter:
Measurement of the yarn consumption in meters or
yards per machine revolution.
Measurement of the yarn infeed in any knitting system,
with and without positive yarn infeed.
Enables quick and easy adjustments, to repeat the
same fabric quality on different machines with identical
gauge but differing cylinder diameters.
Measurement of the yarn tension.
Measurement of the yarn speed.
Option for determining the yarn consumption of indi-
vidual fabric qualities.
The values can be measured and displayed without
having to switch the machine off.
The device is stand alone and transportable.
All required accessories are included in the carry
case.

Maintenance
The following instructions must be observed:
The batteries must not be opened or thrown into
a re.
Replaced batteries must be appropriately disposed
of.
The rechargeable batteries must exclusively be
charged with the supplied original charger unit.
Depending on the local supply voltage, only the
supplied charger (110 to 230 V) may be used for
charging the batteries.
The optimum battery charging temperature range
lies between 10° and 35° C. Cooler or higher tem-
peratures would impair the batteries' quality.
The battery poles must not be short-circuited.
The batteries and the charger must be stored in a
cool and dry place.
With longer storage periods, the batteries may be
subject to self-discharge.
The batteries must be recharged when the LO and
BATT is alternatingly displayed.
They must be recharged by means of the supplied
charging unit until Full is shown on the display
and the running display has come to a
halt.
The batteries' duration cannot be guaranteed if the
charging process is interrupted prematurely.
ATTENTION!
Change of batteries only while MLT WESCO
is off.
Plug the DC connection cable into the MLT WES-
CO.
Plug the charger into a Schuko socket by means
of an adapter.
Battery duration:Approx. 50 hours of normal use.
Cleaning the MLT WESCO
The MLT WESCO may only be cleaned with the help
of a moist cloth.
ATTENTION!
No chemical cleaning agents must be
used.
NOTE!
Before using the MLT WESCO for the rst time, or if it hasn't been used for a while, the unit has to be
charged.
