System Heating and Cooling
Install air conditioning and heating, if necessary, to maintain the ambient temperature within the
appropriate range (as given in the table above). Air conditioning capacity must be consistent
with the BTU ratings given in
Required Conditions for Accuracy Enhanced Measurement
Accuracy-enhanced (error-corrected) measurements require the ambient temperature of the
N5251A to be maintained within ± 1

5 C to 40 C (41 F to 104 F)
-40 C to +65 C (-40 F to +158 F)
20 C to 26 C (68 F to 79 F)
Temperature must be within 1 C (1.8 F)
of the temperature at which the
measurement calibration was performed.
Type tested at 95%, +40 C (non-condensing)
Type tested 0 to 4600 meters (~15,000 feet)
