4 Technical Data
4.1 Environmental Characteristics
These environmental characteristics indicate the conditions for safe operation. Instrument
performance may depend on the ambient conditions.
Operating Temperature +5° C to +40° C (+41° F to +104° F)
Non-Operating
Temperature +0° C to +55° C (+32° to +131° F)
Operating Altitude Up to 2,000 m (6,562 ft.)
Relative Humidity 0% to 80% non-condensing for temperatures up to 31° C,
decreasing linearly to 50% at 40° C.
Non-Operating Relative
Humidity 0% to 95% non-condensing.
Pollution Degree Pollution degree 2.
Normally no pollution or only dry, non-conductive pollution
occurs. The pollution has no influence. Occasionally,
however, a temporary conductivity caused by condensation
may be expected.
Table 4.1: Environmental Characteristics
For indoor use only.
Avoid sudden, extreme temperature changes which could cause condensation on circuit
boards in the device.
