SOURCE I MODE, MANUAL OHMS: Total uncertainty = I source accuracy
+ V measure accuracy (4-wire remote sense).
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
(except 1A, 3A and 10A ranges). Max. Guard Output Current: 50mA.
Accuracy is load dependent. Refer to White Paper no. 2033 for calculation
formula.
GUARD OUTPUT IMPEDANCE: <0.1Ω in ohms mode.
1. Speed = Normal (1 PLC). For 0.1 PLC, add 0.005% of range to offset specifications,
except 200mV, 1A, 3A, 10A ranges, add 0.05%. For 0.01 PLC, add 0.05% of range to
offset specifications, except 200mV, 1A, 3A, 10A ranges, add 0.5%; 3A, 10A ranges add
15mA.
2. Accuracies apply to 2- or 4-wire mode when properly zeroed.
3. 4-wire mode.
4. Manual ohms only.
5. In pulse mode, limited to 0.1 PLC measurement.
6. 10A range only in pulse mode.
