Step 3. Using a syringe, feed the sample into the housing.
Slowly pull out the syringe plunger taking approx. 5 seconds to suction 10 mL of the
sample. Then slowly push in the syringe plunger taking approx. 5 seconds to discharge
all of the sample solution in the syringe.
(The sample is fed into the housing with this suction and discharge process.)
Slowly move the syringe plunger so that air bubbles do not form in the measurement
sample in the housing.
When suctioning for the first time, air bubbles will enter the syringe. Hold the syringe
upwards and move the plunger to discharge the air bubbles.
Step 4. Repeat this suction and discharge process.
Repeat the suction and discharge process in Step 3 one to two times to feed a total of
20 to 30 mL
of sample
into the housing. The syringe does not need to be facing upward after the second time.
Step 5. Spin the stirrer to mix the solution.
The automatic stability decision function automatically decides the stability of the indicated value, and holds the
stabilized value.
The “automatic stability decision function” eliminates the read indicated value variation. When the
measurement is started, the stability of the indicated value is automatically decided and is then held or
canceled.
If the stirrer is rotated at high speed, the magnetic stir bar may pop off with force and damage the
oxygen sensor. Gradually increase the stirrer speed.
If the stirrer speed is too slow, the flow will be insufficient, and the measurement value may be low.
Adjust the speed to the maximum speed that does not cause the magnetic stir bar to pop off.
The recommended speed for the stirrer (Model: KK accessory) is 1,100 to 1,400 rpm.
(For similar viscosity as water)
To ensure an accurate measurement, adjust the stirrer speed during calibration and measurement.
Step 6. To save the measurement value in the main unit, press the key.
”Save Complete” is displayed, and the previous stability decision value is saved in the measurement history by
the memory function.
The “Memory Function” saves the held measurement value as the measurement history. If the key is
pressed while “Save” is displayed, the measured value will be saved in the main unit as the measurement
history. The saved details are retained even if the power is turned OFF, the batteries are removed, or the AC
adapter is disconnected.
Press on the Measurement Standby Screen to confirm the measurement history. The Measurement
History Screen will open. Refer to the “Measurement and recording” section in the PACK MASTER Operation
Manual for details on the functions and operations.
