Speed = Normal (1 PLC). For 0.1 PLC, add 0.005% of range to offset specifications, except 200mV, 1A, 10A
ranges, add 0.05%. For 0.01 PLC, add 0.05% of range to offset specifications, except 200mV, 1A, 10A
ranges, add 0.5%.

Accuracies apply to 2- or 4-wire mode when properly zeroed.
3
4-wire mode.
4
Manual ohms only – except 2420, 2425, 2430, 2440 for 2

range.
5
Source readback enabled, offset compensation ON. Also available on 2410, 2420, 2425, 2430, and 2440
with similar accuracy enhancement.
6
10A range only in pulse mode.
7
In pulse mode, limited to 0.1 PLC measurement.
8
Except 2440; default test current is 5µA.

SOURCE V MODE, MANUAL OHMS: Total uncertainty = V source accuracy
+ I measure accuracy (4-wire remote sense).
6-WIRE OHMS MODE: Available using active ohms guard and guard
sense. Max. Guard Output Current: 50mA (except 1A range). Accuracy
is load dependent. Refer to White Paper no. 2033 for calculation
