Environmental Specifications

The environmental specifications are provided in the following paragraphs.

Warmup Time

1 hour to rated specifications

15 minutes when relative humidity is kept below the rated maximum minus 20% (e.g. below 70% for a 90% maximum rating).

Operating Temperature

0°C to 60°C

Storage Temperature

-40°C to +75°C

Instrument storage at temperature extremes may necessitate adding up to 0.008% to the dc and ac voltage accuracy specifications. Alternatively, any resulting shift can be compensated for by recalibrating the instrument.
