ENGINEERING MODE
This is the engineering setting mode. It is used for
data that are registered or changed less frequently
than in the Operator’s Mode.
Settings can be registered or changed when write
protect is set to level 0 or 1. When the level is 2 or
3, only configuration data monitoring is available.
Includes ID function setting, detector data, flow
rate span, hysteresis width, pulse data, low flow
cut, output at error.
Mode Explanation
Note:
• When registering or changing data, be
sure to press the MODE key to write it to
non-volatile memory. Rewriting occurs
when the mode is changed to the Measur-
ing mode by pressing the MODE key.
MAINTENANCE MODE
This is the maintenance setting mode. It is used
when adjustment or verification is needed at regu-
lar maintenance periods or when an abnormality
occurs. Settings can be adjusted or confirmed
only when the write protect level is set at 0.
Includes loop check, output adjustment, gain ad-
justment.
This mode is further divided into the following 3
modes:
OUTPUT CHECK MODE
CALIBRATION MODE
CRITICAL MODE
Notes:
• Calibration Mode and Critical Mode con-
tain adjustments and operations that are
very important for flow rate measure-
ment. When operating these modes,
fully check the details of the adjustments
to be made.
Missetting will prevent measurement.
• When registering or changing data, be
sure to press the MODE key to write it to
non-volatile memory. Rewriting occurs
when the mode is changed to the Mea-
suring mode by pressing the MODE key.
