Operation Precautions
BEFORE CONNECTING THE POWER SENSOR TO OTHER INSTRUMENTS, ensure that
WA R N I N G
all instruments are connected to the protective (earth) ground. Any interruption of
the protective earth grounding will cause a potential shock hazard that could result
in personal injury and cause damage to the power sensor.
If the following energy and power levels are exceeded, the power meter
system may be damaged.
Maximum torque at the connector should not exceed 12 in- lb (135 Ncm)
for the Type- N connector, or 8 in- lb (90 Ncm) for the 3.5- mm connector
to avoid damage to the connector.
Connect the power sensor by turning only the hex nut portion of the
connector. Damage can occur if torque is applied to the power sensor
body.
The connector plastic insulator bead deteriorates when contacted by
acetone, trichloroethylene, carbon tetrachloride, benzene, etc. Refer to
Application Note 326, Principals of Microwave Connector Care (5954- 1566)
or Microwave Connector Care (08510- 90064) for proper cleaning methods.
