Test Considerations
For optimum performance, all procedures should comply with the following
recommendations:
– The performance verification test or adjustment should be performed under a
laboratory condition, where the ambient temperature can be controlled.
– Ensure that the calibration ambient temperature is stable and is between 18 °C
and 28 °C. Ideally the calibration should be performed at 23 °C ± 1 °C.
– Ensure that the ambient relative humidity is less than 80%.
– The instrument should be in the laboratory environment for at least 1 hour
prior.
– Allow a warm-up period of 3 minutes.
– Use shielded twisted-pair PTFE-insulated cables to reduce settling and noise
errors. Keep the input cables as short as possible.
