SOURCE I MODE, MANUAL OHMS: Total uncertainty = I source ac V measure accuracy (4-wire remote sense).
SOURCE V MODE: Total uncertainty = V source ac I measure accuracy (4-wire remote sense).
6-WIRE OHMS MODE: Available using active ohms guard and guard sense. Max. Guard Output Current: 50 mA (except 1A and 3A
ranges). Accuracy is load dependent. Refer to manual for calculation formula.
GUARD OUTPUT IMPEDANCE: 0.1 in ohms mode.
1 Speed = Normal (1 PLC). For 0.1 PLC, add 0.005% of range to offset specifications, except 200mV, 1A ranges, add 0.05%; 3A/10A range, add 1.5mA. For
0.01 PLC, add 0.05% of range to offset specifications, except 200mV, 1A ranges, add 0.5%; 3A/10A range, add 15mA.
2 Accuracies apply to 2- or 4-wire mode when properly zeroed.
3 4-wire mode.
4
Manual ohms mode only.
5 Source readback enabled, offset compensation ON.
6 10A range only in pulse mode.
7 In pulse mode, limited to 0.1 PLC measurement.
