oxygen content not higher than 20.9%.
Perform calibration at an ambient
temperature of 20±5 °С.
If the gas detector was used or placed
for storage at a negative temperature, hold the
gas detector within 3–4 hours at a temperature
from 0 to +30 °С before the calibration.
Perform zero calibration at a temperature and
environmental relative humidity corresponding to
the measurement conditions.
Perform span calibration at least one time per
6 months.
