Table 1.2: Delayed Mode Accuracies with Respect to Reference Current
(±) ACCURACY; 18-28 °C (64.4-82.4 °F); 1 YEAR (after initial 6 month cycle).
In the fast mode, the published accuracy for all reference current ranges is +/- (0.05% + 5 counts).
These accuracies are displayed in Table 1.3. Fast Mode is not available for all ranges. If the unit is in
Fast Mode and a range is selected that Fast Mode is not available, then the instrument will default to
Delayed mode.
