1-3 Performance Verification Models 2510 and 2510-AT
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 2510 requires a line voltage of 100 to 240V and a line frequency of 50 or 60Hz.
Verification tests must be performed within this range.
Recommended test equipment
Table 1-1 summarizes recommended verification equipment and pertinent specifications.
You can use alternate equipment as long as that equipment has specifications at least as good as
those listed in Table 1-1. Keep in mind, however, that test equipment uncertainty will add to the
uncertainty of each measurement. Generally, test equipment uncertainty should be at least four
times better than corresponding Model 2510 specifications.
