CAUTION
*1: When performing the Insulation Resistance Test or the
Withstand Voltage 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.
• When the power terminal has a lighting protector
(optional code A), remove the short bar at the ground
terminal.
• After testing, be sure to discharge by using a resistance
and return all wires and the short bar 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.
Safety Requirement Standards:
EN61010-1
• Altitude at installation site: Max. 2000 m above sea leve
• Installation category based on IEC1010:
Overvoltage category II (“II” applies to electrical equip-
ment which is supplied from the fixed installation like
distribution board.)
• Pollution degree based on IEC1010
Pollution degree 2 (“Pollution degree” describes the
degree to which a solid, liquid, or gas which deteriorates
dielectric strength or surface resistivity is adhering. “2”
applies to a normal indoor atmosphere.)
EMC Conformity Standards: ,
EN61326-1 Class A, Table 2 (For use in industrial locations)
EN61326-2-3
EN61000-3-2 ClassA
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.
■ NORMAL OPERATING CONDITIONS
Ambient Temperature: –40 ° to +60°C (–40° to +140°F)
*1: Minimum temperature should also be limited according
to minimum fluid temperature of flow tube’s
specification.
Refer to description of “Fluid Temperature and
Pressure”.
*2: Indicator’s operating range (integral flowmeter): –20 ° to
+60 °C (–4° to +140°F)
*3: Maximum temperature should be +50 °C (+122°F) in the
case of power supply code 2 (integral flowmeter).
Ambient Humidity: 0 to 100%
Lengthy continuous operation at 95% or more is not
recommended.
Power Supply (integral flowmeter):
Power supply code 1:
• AC specifications
Rated power supply: 100 to 240 V AC, 50/60 Hz
(Operating voltage range: 80 to 264 V AC)
• DC specifications
Rated power supply: 100 to 120 V DC
(Operating voltage range: 90 to 130 V DC)
Power supply code 2:
• AC specifications
Rated power supply: 24 V AC, 50/60 Hz
(Operating voltage range: 20.4 to 28.8 V AC)
• DC specifications

Fluid Conductivity:
Size 2.5 to 10 mm (0.1 to 0.4 in.): 5 µS/cm or larger
Size 15 to 125 mm (0.5 to 5 in.): 1 µS/cm or larger
Size 150 to 400 mm (6 to 16 in.): 3 µS/cm or larger
Note: For a fluid with large flow noise (pure water, pure
alcohol or others), or a fluid wth low conductivity and
low viscosity, the output fluctuates and is impossible
to measure accurately.
Size 500 to 2600 mm (20 to 104 in.) : 50 µS/cm or larger.
