Check the Temperature and Humidity

1. Measure the temperature and humidity of the environment and record the values in
Table 2-14, "Performance Test Record for All Models," on page
specified at an ambient temperature of +23 ±3 °C. Therefore, the environmental
temperature must remain in the range of +20 °C to +26 °C. Once the measurement
calibration has been done, the ambient temperature must be held to range of ± 1 °C.
2. Open the calibration and verification kits and place all the devices on top of the foam so
they will reach room temperature. The temperature of the devices is important because
device dimensions and therefore the electrical characteristics change with temperature.
3. Switch on the power to the analyzer.
NOTE To achieve the maximum system stability, allow the analyzer to warm up for
at least 30 minutes.
