Verification test requirements
Be sure that you perform the verification tests:
•
•
•
•
•
Environmental conditions
Conduct your performance verification procedures in a test environment with:
•
•
Warm-up period
Allow the Model 2520 to warm up for a minimum of one hour before conducting the
verification procedures.
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.
Typically, allow one extra hour to stabilize a unit that is 10°C (18°F) outside the specified
temperature range.
Also, allow the test equipment to warm up for the minimum time specified by the
manufacturer.
Line power
The Model 2520 requires a line voltage of 100V to 240V and a line frequency of 50 or
60 Hz. Verification tests must be performed within this range.
Under the proper environmental conditions.
After the specified warm-up period.
Using the correct line voltage.
Using the proper test equipment.
Using the specified output signals and reading limits.
An ambient temperature of 18-28°C (65-82°F).
A relative humidity of less than 70% unless otherwise noted.
