Performance Verification 18-3
Verification test requirements
Be sure that you perform the verification tests:
• Under the proper environmental conditions.
• After the specified warm-up period.
• Using the correct line voltage.
• Using the proper test equipment.
• Using the specified test signals and reading limits.
Environmental conditions
Conduct your performance verification procedures in a test environment with:
• An ambient temperature of (18-28˚C) 65-82˚F.
• A relative humidity of less than 70% unless otherwise noted.
Warm-up period
Allow Model 6514 to warm up for at least one hour before conducting the verification proce-
dures. If the instrument has been subjected to temperature extremes (those outside the ranges
stated above), allow additional time for the instrument's internal temperature to stabilize. Typi-
cally, allow one extra hour to stabilize a unit that is (10˚C) 18˚F outside the specified temperature
range.
Allow the test equipment to warm up for the minimum time specified by the manufacturer.
Line power
Model 6514 requires a line voltage of 100/120 VAC or 220/240 VAC at a line frequency of
50 or 60Hz. Verification tests must be performed within this range.
