Scaling
Scaling is used to set the maximum value (main setting (MAX)) and minimum value (main setting (MIN))
of the output range to your liking within the selectable range of each range. This enables the output
divider, deviation, and sweeping features of the 2560A to be used on a wider scale. Scaling cannot be
used in high resolution mode.
• Output divider, deviation, and sweep features (explained later) operate assuming (main setting (MAX)
– main setting (MIN)) to be 100%.
• To calibrate a 4-20 mA meter at 4 mA, 8 mA, 12 mA, 16 mA, and 20 mA, set the main setting (MAX)
to 20 mA and the main setting (MIN) to 4 mA. The output divider and deviation features can be used
to calibrate at each of these currents.
• To calibrate a meter that has positive and negative range, a digital meter, or the like, set the main
setting (MIN) to a negative value and the main setting (MAX) to a positive value. The output divider,
deviation, and sweeping features can be used to calibrate over the span specified by these values.
