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.
