1. 90-day specifications show full-range accuracy of recommended model used for specified point.
2. Resistor used to adjust 3 A and 10 A ranges should be characterized to uncertainty shown using resistance
function of a digital multimeter before use.
3. Used for contact check adjustment. Characterize resistors using ohms function of digital multimeter
before use.
4. Refer to Pulse loads (on page 13-3).
Adjustment overview
Adjustment steps must be performed in a specific sequence, as shown in the following table. Each
range is adjusted using four points:
â–ª + ZERO
â–ª + FULL SCALE
▪ − ZERO
▪ − FULL SCALE
The full-scale parameters are 90 percent of full-scale unless otherwise noted (see the table in Step
sequence (on page 13-22)). Note that you cannot send a value of 0 for the two zero parameters.
Instead, you must send a very small value, such as 1e-30 or -1e-30.
The following table lists the sense modes for the adjustment steps.
