2.2 Mounting and installation
2.2.1 Location of installation
z Install the instrument with all the four foot-stands of the instrument on the level plane, e.g., on an
appropriate desk surface, so that the instrument will be stationed stable.
z This instrument uses a forced air cooling system with a fan. If you notice the fan stopped,
remove immediately the power supply and report to NF Electronic Instruments or NF’s
agent/dealer.
If you continue to use the instrument with the fan stopped, there is a risk of expansion of damages
and hence difficulty/impossibility of repair.
z Air intake and exhaust ports are located on the side, rear and bottom surfaces of the instrument.
Therefore , it is requested to install the instrument 10 cm apart from the wall at minimum.
2.2.2 Criteria for location of installation
a)
Use the instrument under the following range of temperature and humidity environment.
Note that the pollution condition is degree 2.
Environmental temperature: 5 to +35
°
C
Environmental humidity: 5 to 85 % RH (relative humidity) , 1 to 25 g/m
3
(absolute humidity)
Use the instrument under the environment without dew condensation.
b)
Do not install the instrument at locations as follows:
•
Environment with flammable gas
If the instrument is placed in environment with flammable gas, there will be a high risk of
explosion. Never install, use or operate the instrument in such environment.
•
Places with direct sunshine or near fire or heat sources
If the instrument is installed or operated at a place with direct sunshine or near fire or heat
sources, it may not meet the performance specifications or instrument failures may be
induced.
•
Environment with corrosive gas, moisture or dust, or with high humidity
If the instrument is installed in such environment, it could be corroded or instrument
failures could be caused.
•
Places near high voltage equipment, power cables or high electromagnetic field sources
Operating the instrument at such a place could cause malfunctions and/or measurement
errors.
•
Environment with vibration
Operating the instrument in such environment could cause malfunctions and/or failures.
In addition, signal cables for measurement shall be so routed that they will be immune from
interference/induction with noise or electric power by separating them from power supply cables
of this instrument or otherwise. If signal and power supply cables are routed close to each other,
there could be malfunctions and/or measurement errors.
