2.1 Operational Test (Models 409-004
and 409-005) (See Figure 2-1)

In order to effectively diagnose a malfunction of the 409­004 and 409-005 Pediatric Examination Table, it may be

necessary to perform an operational test as follows:

WARNING

Refer to the Operator Manual for com-

plete instructions on operating the
table. Failure to do so could result in personal
injury.

NOTE

The Operational Test, for the most part, only
describes what should happen when the table is
operated. If the table does something other than
described, a problem has been discovered. Refer to
the Troubleshooting Guide to determine the cause of
the problem and its correction.

Also, this operational test procedure is based on units
that have a beam scale; some units do not have a
beam scale - For these units skip to step 14.

(6) Remove any items from table top. Set large

poise weight to zero, making sure it is seated in
notch and set small poise weight to zero, mak­ing sure small poise weight is pushed firmly
against shoulder of beam.

(7) Observe. The beam pointer should balance in

center of trig square, indicating scale is zeroed.

NOTE

Use the calibrated test weight which should be hang­ing on a storage hook on the right rear of the table.
The test weight will have a label indicating the cali­brated weight of the test weight.

(8) Place the calibrated test weight on center of

upholstered table top.

(9) Using the large poise weight and small poise

weight, set beam scale to a setting which is
equal to calibrated test weight.

(10) Observe. The beam pointer should center in

the trig square indicating beam scale is within
tolerance.

(1) Move table top locking handle to LOCK posi-

tion. Attempt to move table top (See
Figure 2-1).

(2) Observe. The table top should be firmly locked

into a stationary position.

(3) Move table top locking handle to UNLOCK posi-

tion.

(4) Observe. The table top should not be locked

into a stationary position anymore. Look
between table top and base. There should be
approximately a 1/4 in. (6.35 mm) gap between
locking rails and bottom of table top; at the very
least, there should not be any contact.

(5) Push down on center of table top a few times to

align and exercise all internal scale parts.

(11) If beam scale does not center, adjust the small

poise weight and/ or large poise weight as nec­essary to center beam pointer in trig square.

(12) Determine how much beam scale reading dif-

fers from weight of calibrated test weight. The
allowable tolerance is ±1 oz. (28.3 g).

(13) Hang the calibrated test weight on its storage

hook, located on right rear of table.

(14) Remove any items from table top and then

move table top locking handle to LOCK posi­tion.

(15) Extend linear scale fully. Using a carpenter

square, check to see if the linear scale is
square with back of table top when scale is fully
extended.

TANITA BWB-800 operating Instructions Man­ual).

(4) Press KG / LB button until display is set to LB.

NOTE

Use the calibrated test weight to perform the follow­ing procedure.

(6) Determine how much digital scale reading dif-

fers from weight of calibrated test weight. The
allowable tolerance is ±5.25 oz. (150 g).

(7) Remove calibrated test weight and then press

ON / ZERO to turn digital scale OFF.

(8) Extend linear scale fully. Using a carpenter

square, check to see if the linear scale is
square with back of table top when scale is fully
extended.

2.3 Troubleshooting Procedures
(Applies to 409-004 and 409-005)

Table 2-1 is a Troubleshooting Guide which is used to
determine the cause of the malfunction. This guide cov­ers problems with scale platform components, beam
scale components, and linear scale components which
the model 409-004 has. The model 409-005 does not
have a scale platform or beam scale; it only has a linear
scale. For this model, only use the portion of the guide
which is applicable.

(5) Place a calibrated 25 lb (11.3 kg) test weight on

center of table top.

Table 2-1. Troubleshooting Guide (Models 409-004 & 409-005)

Problem Symptom Probable Cause Check Correction

Table top will not lock into
stationary position prop­erly.

Weight scale does not
measure weight accurately.

When table top locking
handle is moved to the
LOCK position, the table
top is not locked into sta­tionary position (can still be
moved).

The beam pointer will not
center when the large and
small poise weights are set
to zero.

The measured weight of
the patient is inaccurate.

Table top locking mechanism
has bent, broken, or missing
components.

Platform has worn “V” bear­ings or a broken pivot.

The beam scale is not
zeroed.

Paper roll is interfering with
table top.

Locking rails are not releas­ing properly when table top
locking handle is moved to
the UNLOCK position.

Check for bent, broken,
or missing components.

Check for worn “V” bear­ings or a broken pivot.

Check to see if the beam
pointer centers when the
large and small poise
weights are set to zero.

Check to see if paper roll
is in contact with bottom
of table top.

Check for bent or missing
components in table top
locking mechanism. See
why locking rails are
“hanging up”.

Replace any bent, broken, or
missing components on the
table top locking mechanism.
Refer to para 4.5 to gain
access.

Replace platform assembly
and beam scale assembly (are
a factory matched unit). Refer
to para 4.2 and 4.5.

PARTS LIST

6.1 Introduction

The illustrated parts list provides information for identify­ing and ordering the parts necessary to maintain the
unit in peak operating condition. Refer to paragraph 1.5
for parts ordering information.

6.2 Description of Columns

The Item column of the parts list gives a component its
own unique number. The same number is given to the
component in the parts illustration. This allows a part
number of a component to be found if the technician
can visually spot the part on the illustration. The techni­cian simply finds the component in question on the illus­tration and notes the item number of that component.
Then, he finds that item number in the parts list. The
row corresponding to the item number gives the techni­cian the part number, a description of the component,
and quantity of parts per subassembly. Also, if a part
number is known, the location of that component can be
determined by looking for the item number of the com­ponent on the illustration.

The Part No. column lists the MIDMARK part number
for that component.

The Description column provides a physical description
of the component.

The Qty. column lists the number of units of a particular
component that is required for the subassembly. The
letters “AR” denote “as required” when quantities of a
particular component cannot be determined, such as:
adhesive.

Bullets { • } in the Part No. column and the Description
column show the indenture level of a component. If a
component does not have a bullet, it is a main compo­nent of that illustration. If a component has a bullet, it is
a subcomponent of the next component listed higher in
the parts list than itself that does not have a bullet. Like­wise, if a component has two bullets, it is a subcompo­nent of the next component listed higher in the parts list
than itself that has only one bullet.

6.3 Torque Specifications and Important
Assembly Notes

When specific assembly torque specifications, mea­surements, or procedures have been identified, by our
engineering department, as required to assure proper
function of the unit, those torque specifications mea­surements, and procedures will be noted on the parts
illustrations. Adherence to these requirements is essen­tial.
