Note: The accuracy of a product before shipment is defined
as totalized value at the result of calibration test in
our water actual flow test facility.
Calibrated conditions in our water actual test facility
are as follows:
Fluid temperature: 20 ± 10°C
Ambient temperature: 20 ± 5°C
Length of straight runs:
10 D or more on the upstream side
5 D or more on the downstream side
Reference conditions:
Similar to BS EN29104, ISO 9104
Accuracy (Current Output):
Accuracy (Pulse Output) plus ±0.05% of span
Repeatability:
±0.2% of rate (V ≥ 1m/s (3.3ft/s))
±0.1% of rate ± 1mm/s (V < 1m/s (3.3ft/s))
Maximum Power Consumption:
Combined with AXFA11: 20W
Insulation Resistance:
Between excitation current terminal and signal
/ common terminals : 100MΩ at 500V DC
Between signal terminals : 100MΩ at 500V DC
Between signal terminals and common termi-
nal (C) : 100MΩ at 500V DC
CAUTION
*1: When performing the Insulation Resistance
Test, please obey the following caution.
• Following the relevant test, wait for more
than 10 seconds after the power supply has
been turned off before removing the cover.
• Remove all wires from terminals before
testing.
• After testing, be sure to discharge by using
a resistance and return all wires to its
correct position.
• Screws must be tightened to a torque of
1.18 N-m or more.
• After closing the cover, the power supply
can be restored.
EMC Conformity Standards:
EN61326-1 Class A, Table2 (For use in indus-
trial locations)
EN61326-2-3
EN61000-3-2 Class A
EN61000-3-3
CAUTION
This instrument is a class A product, and it is
designed for use in the industrial environment.
Please use this instrument in the industrial
environment only.
