Test Consideration
For optimum performance, all procedures should comply
with the following recommendations.
• Ensure that the calibration ambient temperature is stable
and between 23 °C ± 3 °C.
• The ambient relative humidity must be less than 80%.
• Allow a one-hour warm-up period before verification or
adjustment.
• Keep the measurement cables as short as possible and
consistent with the impedance requirement.
• Use RG-58 or equivalent 50
Ω cable.
