3-2. Factor calibration with pure water
For correct measurement, the meter needs to be checked and adjusted to the reference using the
density standard of water.
Prior to each day’s work, measure the water by pressing [MEAS] key to make sure the result of specific
gravity (SG) shows a value within ± 0.0005 of the nominal value of pure water at the test temperature. If
the measuring cell and tube lines were filled with ethanol (for short-term storage), wash out the ethanol
with as much pure water before measurement is started. If the result shows a SG (t/t) value outside of
the ± 0.0005 range, repeat the cell cleaning and re-measure the water standard. If the measurement
results for pure water continue to fall outside of this range, the meter should be factor calibrated as
follows:
Note:
The measuring cell must be cleaned with water before calibration. Care

Note:
Prior to each day’s work, measure pure water by pressing [MEAS] key to
make sure the result of specific gravity (SG) shows a value within
± 0.0005 of the nominal value of pure water at the test temperature. If the
measuring cell and tube lines were filled with ethanol (for short-term
storage), wash out the ethanol with as much pure water before
measurement is started. If the result shows a SG (t/t) value outside of the
± 0.0005 range, repeat the cell cleaning and re-
outside of this range, the meter should

3-4. Clean measuring cell after measurements
The measuring cell must be cleaned when a different type of sample is to be measured or when a series
of measurement is complete. Follow the following steps:
Instrument with optional peristaltic pump
1) Remove the sampling tube from the sample and wipe with tissue paper.
2) Put the sampling tube into the cleaning solution/solvent and draw the solution/solvent with [PUMP]
key. For more effective cleaning, we suggest that you pull out the tube from the solution/solvent
momentarily (while the pump is running) - several times to draw in some air. Continue pulling
solution/solvent until roughly 10 mL have been pulled through the cell. Some samples may require
more than 10 mL of cleaning solution/solvent to effectively remove the sample from the cell (see
note below).
3) Take the sampling tube out of the cleaning solution/solvent. When the solution/solvent is clear from
the sample tube, press [PUMP] key to stop the pump.
4) Remove the sampling tube from the cleaning solution/solvent and wipe with tissue paper.
Instrument without pump
1) Remove the sample syringe from the sample inlet and wipe the inlet with tissue paper.
2) Ensure the sampling tube (outlet) on the D155 (upper port) is placed in a suitable waste container
such as a beaker or bottle.
3) Fill a 10 mL syringe with cleaning solution/solvent and inject the solution into the cell. Periodically
remove the syringe and re-insert to allow air to be introduced into the cell for more effective cleaning.
Repeat this step if necessary. Some samples may require more than 10 mL of cleaning
solution/solvent to effectively remove the sample from the cell (see note below).
Note:
When viscous samples are measured, rinse the
thoroughly with the cleaning solvent/solution to remove the sample.
Correct measurement results cannot be expected if any residue of the
previous sample remains in the measuring cell.

3-5. Procedure after a day’s measurements
When the day’s work of measurement is completed, the measuring cell needs to be cleaned with the
cleaning solution/solvent and be filled with pure water in order to avoid contamination on the glass
measurement cell walls:
1) Clean the measuring cell according to the steps in Section 3-4.
2) When certain oily substances or deposits are adhered to the cell, follow the steps in Section 5-1-1.
3) Fill the measuring cell with pure water:
a. If using the optional peristaltic pump, put the sampling tube into pure water and press [PUMP]
key to draw water into the cell. When the cell is filled with pure water, press [PUMP] key to
stop the pump.
a. If using a syringe, inject two full 10mL syringes so that a total of 20 mL is flushed through the
cell.
When the unit is not used longer than one week, the cell should be filled with 99% or higher
concentration of Ethanol instead of pure water in order to avoid the growth of mold inside the cell.
23
Note:
When the cell is filled with Ethanol for storage, flush the inside cell with
at least 20mL pure water using either a syringe or the [PUMP] key if using
the optional peristaltic pump before starting next cal
measurement. If the residue of Ethanol remains in the cell or tube lines,
correct calibration or measurement cannot be performed.

The optional printer can be connected to the D155 unit so that the measurement and calibration results
together with the date and time of measurement can be printed out. Connect the supplied printer cable
to the RS-232C port (DB-9M) on the back of D155 unit as shown.
A personal computer (PC) can be connected instead of the printer so that data can be exported. A
data collection software package – SOFT-CAP Data Capture Software is available as an option with the
D155. Please consult the separate SOFT-CAP Operation Manual for more details on installation and
use.

5. Maintenance
5-1. Daily check
5-1-1. Cleaning the measuring cell
When the repeatability of measurements has degraded or measuring time is prolonged, the measuring
cell is considered to be contaminated. Also, when the cell is apparently contaminated with a sample of
such nature, the measuring cell must be cleaned with an appropriate solvent like household chlorine
bleach, acid or alkali. When particular samples containing fatty acids or protein (such as biodiesel) are
measured, the cell must be cleaned once a week as described below.
The following example describes how to rinse out fats and oils with Sodium hydroxide:
1) For units with the optional peristaltic pump installed
a. Insert the sampling tube into 0.1∼0.5mol/L Sodium hydroxide and press [PUMP] key to inject.
b. When the cell becomes filled with Sodium hydroxide, press [PUMP] key to stop filling.
c. Leave the sodium hydroxide in the cell for about 15 minutes.
d. Drain out Sodium hydroxide solution with [PUMP] key.
2) For units without the pump
a. Inject 0.1∼0.5mol/L Sodium hydroxide using a suitable 2-5 mL syringe.
b. Leave the sodium hydroxide in the cell for about 15 minutes.
c. Push out the sodium hydroxide from the cell using an empty syringe filled with air.
3) Clean the measuring cell with pure water according to the Step “3-4”.

7-2. Principle of measurement
7-2-1. Oscillating U-tube Cell
When a measurement cell filled with liquid or gas is oscillated spontaneously, resultant oscillating cycle
varies with the density of the sample in the measurement cell. The oscillating cycle T is expressed
follows.
where,
d = Density of sample in measurement cell
Vc = Volume of sample in measurement cell, or measurement cell internal volume
Mc = Mass of measurement cell
K = Constant
45
Supposing that the oscillating cycles Ta and Tw are obtained through measurement of reference
materials of known density (density da and dw), the facto value F is calculated as follows.
Accordingly, the density “d” of unknown sample can be calculated according to the following formula by
measuring its oscillating cycle T.
