8 Maintenance, Storage and Disposal
The product does not require regular maintenance. It only requires occasional cleaning. It is however
advisable to check the nominal data from time to time.
Regular Checks
If the power sensor is used frequently, check the RF connectors for visible damage - bent inner
conductors, broken contact springs and so on. If the RF connectors are damaged, stop using the power
sensor and contact the Rohde & Schwarz customer service.
Cleaning
1. Disconnect the power sensor:
a) From the DUT.
b) From the computer or base unit.
2. Clean the outside of the power sensor using a lint-free cloth. You can dampen the cloth with water
but keep in mind that the casing is not waterproof. If you use isopropyl alcohol or ethanol instead of
water, be careful not to damage the labeling. Do not use cleaning agents that can damage the
instrument such as solvents, acids or alkalis.
3. Clean the RF connectors as follows:
a) Dislodge any particles using compressed air.
b) Clean the inside and the connector threads using a foam swab or lint free cloth dampened with
isopropyl alcohol or ethanol.
Storage
Put plastic end caps on the RF connectors to protect them from damage. Protect the power sensor against
dust.
Ensure that the environmental conditions, e.g. temperature range and climatic load, meet the values
specified in the data sheet.
