Keysight 34980A Service Guide 5
Environmental Conditions
Keysight 34980A is designed for indoor use in an installation category II and low
condensation environment. Do not use in locations where conductive dust or
electrolytic salt dust may be present. Table below shows the general
environmental conditions for this instrument. Refer to the product data sheet at
https://literature.cdn.keysight.com/litweb/pdf/5989-1437EN.pdf for more
information on the instrument general specifications.
General specifications Requirement
Temperature
Operating condition: 0°C to 55°C
Storage condition: -40°C to 70°C
Humidity
Up to 80% R.H. at 31°C (non-condensing), decreasing
linearly to 50% R.H. at 40°C (non-condensing)
Altitude Up to 2,000 m
Pollution degree 1 or 2
When used in pollution degree 1 conditions, the maximum voltage rating for the
Analog Buses is 300V. When used in pollution degree 2 conditions, the
maximum voltage rating is 100V. If conditions change, ensure that condensation
has evaporated and the instrument has thermally stabilized until pollution
degree 1 conditions are restored before turning on power to the equipment.
Pollution Degree 1: No pollution or only dry, non-conductive pollution occurs.
The pollution has no influence (on insulation) (IEC 61010-1 2nd Edition).
Pollution Degree 2: Normally only non-conductive pollution occurs.
Occasionally, a temporary conductivity (leakage current between isolated
conductors) caused by condensation can be expected (IEC 61010-1
2nd Edition).
