CE Marking:
CE marking is affixed on the name plate except for
models with any of the following specifications.
• Optional Code: FF1, CF1, SF2, JF3
Safety Requirement Standards:
CAN/CSA C22.2 No. 61010-1-04
• Altitude of installation site: Max. 2000 m above sea
level
• Installation category: I
"Overvoltage category (Installation category)"
describes a number which defines a transient
overvoltage condition. It implies the regulation for
impulse withstand voltage. " I " applies to electrical
equipment which is supplied from the circuit when
appropriate transient overvoltage control means
(interfaces) are provided.

• Pollution degree: 2
"Pollution degree" describes the degree to which a sol-
id, liquid, or gas which deteriorates dielectric strength
or surface resistivity is adhering. " 2 " applies to normal
indoor atmosphere. Normally, only non-conductive
pollution occurs. Occasionally, however, temporary
conductivity caused by condensation must be expect-
ed.
• Indoor/Outdoor use
EMC Conformity Standards:
EN61326-1 Class A, Table 2 (For use in industrial
locations)
EN61326-2-3
• Performance Specification during immunity test
Flowrate output: O utput fluctuation within ±3% of
default (1m/s) span
CAUTION
This instrument is a class A product, and it is de-
