TEMPERATURE COEFFICIENT (0°–18°C and 28°–50°C): ±(0.15 × accuracy specification)/°C.
1. Speed = 1 PLC.
2. Accuracies apply to 2- and 4-wire mode when properly zeroed.
3. For sink mode, 1μA to 100mA range accuracy is ±(0.15% + offset*4). For 1A range, accuracy is ±(1.5% + offset*8).
4. Rear panel triax connections only.

TEMPERATURE COEFFICIENT (0°–18°C and 28°–50°C): ±(0.15 × accuracy specification)/°C.
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).
GUARD OUTPUT IMPEDANCE: 0.5W (dc) in ohms mode.
5. Manual ohms only.
6. Source readback enabled. Offset compensation ON.
7. All specifications are guaranteed with output ON.
