Maintenance - TSI Alnor Balometer 6461 Manual Del Usuario

Remove the detachable handle and store it in the
accessory case. The carrying case cannot be closed
with this handle attached to the base.
The base assembly can now be placed in the
carrying case, with the range selector and
Velometer facing to the side (either side) of the
Nylon Hoods
The hoods can be hand washed in cool water with
a mild detergent if needed. When handling do not
let the cloth come in contact with sharp corners or
other objects which may tear the material.
Static Electricity
It is common to encounter static electrical charges,
especially in conditions of low humidity. Included
with the Balometer when shipped from the factory
is a container of anti-static solution which should
be used if the Velometer will not hold a zero
setting, or gives erratic readings. Using a soft lint-
free cloth slightly moistened with anti-static
solution, rub gently over the front of the
Velometer case and window.
Velometer Zero Adjustment
Check to see that the pointer of the Velometer is at
zero each time the meter is put into service. The
zero adjustment screw enables you to make an
adjustment. With the range selector set to OFF,
use a screwdriver to bring the pointer to zero. It
should read zero (within one division) regardless
of how the Balometer is held.

case. The case will not close if the Velometer
faces forward or to the rear.
The 2 x 2 frame (with hood attached, if convenient
for further use) is the last item to be packed. The
frame will be tilted, with the back of the frame
resting on the top of the accessory case.

MAINTENANCE

Manifold
The manifold should be checked before using to
be certain that the sensing holes have not become
clogged with dirt or dust particles. Inspect for
leaks which may be caused by cracks, or by poor
connection to the range selector through the short
pieces of tubing. The manifold can be cleaned
using mild detergent and warm water, without
immersing the manifold in water. It is
recommended that cleaning be done with the
manifold in place, and with extreme care.
When the instrument is stored or otherwise not
being used to take readings, be certain to protect
the meter movement by switching the range
selector to the OFF position.
The air flow sensing manifold can be damaged if
subjected to excessive stress. It is not repairable.
Any air flow other than through the calibrated
sensing holes (even hairline cracks) will affect
instrument accuracy. Special manifold mounting
springs are designed to cushion the assembly and
allow for some deformation of the base without
affecting accuracy. These springs should not be
removed or altered in any way.
Calibration
Your Balometer may be returned to the factory for
calibration.
When shipping the Balometer for factory
calibration, pack it carefully, and follow the
Instructions for Return in this manual.
