3.4 Measurement
You can perform measurement by either of the methods below.

Storing data in memory manually with reference to the measurement value
(single measurement)

Having data stored in memory automatically and continuously
U-51/U-52/U-54: Interval measurement (minimum memory interval of 10 seconds)
U-53: Interval measurement (minimum memory interval of 30 seconds)
Select the measurement method that meets your requirements.
Note

Lower sensor probe slowly when submerging them in samples.

Sensors may break if sensor probe are dropped from a height of 1 meter or more.

Do not submerge sensor probe in water depths of over 30 meters. Sensor probe are only
resistant to water pressure of up to 30 meters.

After turning the power ON, check that the DO readout value has stabilized before starting
measurement (takes around 30 minutes).

If water temperature is different from air temperature by 10

C or more, wait for about 20 minutes
after immersing sensor probe into water. (U-54, U-54)
Tip

When on the measurement screen, pressing the ENTER key enlarges the display and shows
three measured values at a time.

Pressing the up ( △ ) and down ( ▽ ) keys scrolls through the measured values one item at a time.

Pressing the ENTER key again reverts to the normal measurement screen display.
3.4.1 Storing data in memory manually
Follow the steps below to manually store data in memory while referring to the measurement
value to check the readout value is stable.

U-51/U-52/U-54
1.
Check that each sensor and sensor guard is mounted.
