temperature and
humidity range
0°C to 40°C (32°F to 104°F), 20% RH to 80% RH (no condensation)
* 30°C (86°F) or more, wet-bulb temperature 27°C (80.6°F) or less
However, within ±5°C (±9°F) of the calibration temperature.
Calibration temperature
range
Based on the operating temperature of calibration kit.
Guaranteed accuracy
period
1 year (Ensure open/short/load calibration are performed daily before
measurement.)
Warm-up time At least 60 minutes
Calibration face 7-mm terminal face of Model IM9906 Adapter (3.5 mm/7 mm) attached to the 3.5-
mm terminal of test head
(After performing open/short/load calibration with calibration kit)
