2.1.2 Environment requirements
The operating place of the 87230 series USB CW power sensor shall meet the following environment
requirements.
1) Operating environment
The operating environment should satisfy the following requirements:
Table 2.2 Operating Environment Requirements of the 87230 Series
Temperature 10°C ~ 40°C
Temperature range during
error adjustment 23°C ±5°C (allowed temperature deviation during error adjustment<1°C)
Humidity Hygrometer measurement range: 20% ~ 80% (uncondensed) when the
temperature<+29°C
Altitude 0 ~ 4,600 m
Vibration Maximum: 0.21 G, 5 Hz ~ 500 Hz
The above environmental requirements are only defined for the operating environment of the instrument
and are not within the scope of specifications.
2) ESD protection
The static electricity is destructive to electronic components and equipment. Generally, we will use two
anti-static measures, including combination of conductive table mat and wrist combination as well as
combination of conductive floor mat and ankle strap. If these two combinations are used together, a
good anti-static protection can be provided. If the combination is used separately, only the former can
provide protection. For the safety of users , anti-static components must provide an isolation resistance
of at least 1 MΩ to the ground.
Please correctly use the following anti-static measures to reduce electrostatic damage:

Ensure that all instruments are properly grounded to avoid generating static electricity;

Before connecting the coaxial cable to the instrument, contact its inner and outer conductors with
the ground temporarily;

The staff shall wear anti-static wrist straps or adopt other anti-static measures before contacting
joints and core wires or carrying out any assembly operation.
Operating voltage range
The above anti-
static measures can’t be taken in a place where the voltage exceeds 500 V.
