Line power

The Series 2600 requires a line voltage of 100V to 240V and a line frequency of 50Hz or 60Hz.
Verification tests should be performed within this range.

Recommended test equipment

Table 15-1
long as that equipment has specifications equal to or greater than those listed in
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
Series 2600 specifications.

4. Resistor used to test Model 2601/2602 3A range and Model 2611/2612/2635/2636 1.5A
range only should be characterized to uncertainty shown using resistance function of digital
multimeter before use.
5. Standard is a guarded and characterized 1 Gohm resistor used to test Model 2635/2636
100pA to 100nA current ranges.

Verification limits

The verification limits stated in this section have been calculated using only the Series 2600
one-year accuracy specifications, and they do not include test equipment uncertainty. If a
particular measurement falls outside the allowable range, recalculate new limits based both on the
Series 2600 specifications and corresponding test equipment specifications.
