3.6 How to use the Serum gauge.
Capillar tube containing the sample can be inserted correctl without pulling
out the capillar tube holder, if the serum gauge is used as follows.
1. Put the capillar tube treated
centrifugall on the serum gauge.
The border line between blood corpuscles
and serum must be left of the line “A”
as shown in the figure.
2. Hold the capillar tube with the thumb
touching the right side of the gauge.
3. Lift up the capillar tube as it is and
insert it into the capillar holder
until the thumb touchs the top of
the capillar holder
4. Then the slit of the capillar tube holder
must be within the range of the serum
part of the capillar tube.
.
5. The capillar tube can be inserted to
the inside of the instrument because the
holder has no stopper.
In case the capillar tube is broken,
the fragment of it can drop inside without
remaining inside of the capillar holder.

Section – Maintenance and inspection
.1 Adjustment with standard solution
The standard value that is set in the equipment will fluctuate corresponding to
deterioration of the light bulb, so to keep the accurac of the instrument,
confirm the value ever 1 month (assuming 2 hours of usage/da ) or
after the light bulb is replaced or the instrument is not used for a long interval.
*Standard solution to be used for the adjustment must be diluted precisel .
Otherwise, measured value could have error.
.1.1 The procedure of adjustment
1. Turn on the power switch and wait until the LCD displa shows “Read ”.
2. Adjust “ZERO” according to the procedure of 3.1, 3-6 .
3. Prepare standard solution with "Hi Level Check-BIL", manufactured b
International Reagents Corp., Japan or an substitute standard solution.
[Prepare original standard solution]
Remove cap and stopper of Hi Level Check-BIL. Reconstitute each vial with 3mℓ
distilled or deionized water of low bacterial count. Replace the stopper. Leave it as it
is for 5 minutes, then mix well b swirling. A high concentration standard is
obtained.
[To use with BR-5000N]
Empt the standard solution into a larger container. Add 6mℓof distilled or
deionized water and dissolve the standard solution again. Assa value × 1/3
concentration standard is obtained. This is the specified value to be used with
BR-5000N.
* The assa value of Hi Level Check-BIL is specified per each production Lot.
Confirm the value in note enclosed with Hi Level Check-BIL, e.g. assa value for
Lot No. 7324 is 54.0mg/㎗. Specified value is 54.0 ×1/3 = 18.0mg/㎗.
4. Set the standard vbalue of the standard solution according to the section 3.5.1.
5. Fill standard solution into a capillar tube (blue line)
and set it in the capillar holder, then press the “CAL” ke
not less than 2 second.
6. The adjustment will end if the displa shows “Measure End”.
If “Error BBK = x.xxx” is shown, confirm the standard
solution and the procedure of calibration, and calibrate it again.
* Measure the standard solution as the normal sample,
then confirm if the measured value falls within ±0.5 of
the calibrated value.

.2 Indication of alarms
When an alarm is given as the buzzer sounds 3 times and displa value turned on and
off, it is because of one or more of following reasons.
1. The high concentration of the specimen.
(Bilirubin that exceeds a measurement value of 30mg/㎗.)
2. High concentration of hemol sis or turbidit .
(Specimen with hemol sis or turbidit exceeding 250mg/㎗.)
* With case 1. and 2. above, accuratel dilute the specimen with an equal amount of
distilled water, then measure. Then, double the measurement value obtained.
3. The outside of the capillar tube being dirt , or bubbles exist inside.
4. The placement of the serum part being incorrect.
5. The light bulb being deteriorated, or light bulb cables being cut.
6. The placement of the light bulb being incorrect.
