2.1.2 Measurement
Measurement mode
This instrument has four types of measurement modes: “Normal measurement”, “STAT measurement”, “Control
measurement” and “Check measurement”. Press on the [Standby screen] to change the measurement mode. The
figures below show the appearance of the [Standby screen] for each of the four measurement modes.
Operational mode
Two operational modes are available, which affect the starting of measurements and operations during measurement.
Auto start
When a dipped test strip is placed on the inlet, it will be detected by the auto start sensor in the section, and fed to the
photometric section in 7-second intervals. You do not need to press the button to start a measurement. When a
test strip is sensed, a short beep sounds. Subsequently placed test strips will be detected and measured in 7-second
intervals. The timing buzzer can be set to “OFF” using the procedure explained in “3.7.9. No.006: Buzzer sound ON/
OFF” on page 3-28.
Cycle start
Press the button to start measurement from the standby status. The timing buzzer signals the test strip dipping
timing to the user. After each test strip is placed on the inlet, it is fed to the photometric section in 7-second intervals.
The inlet lever operates in 7-second intervals continuously regardless of whether a test strip is placed on the inlet
section, and both the timing buzzer and the lever operate in the same interval. The timing buzzer can be set to “OFF”
using the procedure explained in “3.7.9. No.006: Buzzer sound ON/OFF” on page 3-28.
REFERENCE:
The operational mode in effect when the instrument is turned ON can be selected. The standard setting is “auto
start” (See “3.7.8. No.005: Operational mode when turning ON” on page 3-27). The timing buzzer signals the user
the period (approx. 2 seconds) for dipping test strips in samples.
