2.3 Storage Precautions
If the instrument is to be stored for a long period of
time after delivery, observe the following points.
The instrument should be stored in its original
packing condition in the storage location.
Select a storage location that fulfils the following
conditions:
• A place where it will not be exposed to rain or
water
• A place subject to minimal vibrations or shocks
• Temperature and humidity levels should be as
follows:
Temperature: -30 to 70°C
Humidity: 5 to 80% RH (no condensation)
The preferred ambient temperature and
humidity levels are 25°C and approximately
65% RH.
If the AXF magnetic flowmeter is transferred to the
installation site and stored without being installed,
its performance may be impaired due to the infiltration
of rainwater and so forth. Be sure to install and
wire the AXF magnetic flowmeter as soon as
possible after transferring it to the installation
location.
