Electrical Specifications:
(Specifications apply from +18°C to +28°C unless stated otherwise. All specifications assume a 5-minute warm-up period.)
Ohms Measure
Range (Ω) | Accuracy (% of Reading + Floor) |
0.00Ω to 400.00Ω | 0.015%+0.05Ω |
400.0Ω to 4000.0Ω | 0.015%+0.5Ω |
4000.0Ω to 7000.0Ω | 0.03%+1.0Ω |
Read accuracy is based on 4-wire input. For 3-wire ohm measurements, assuming all three leads are
matched, add 0.05 Ω (0.00 Ω~400.00 Ω), 0.2 Ω (400.0 Ω~4000.0 Ω), and 1 Ω(4000.0Ω~7000.0Ω) to the
specifications. Temperature coefficient：(± 0.002% of reading ±0.002% of range)/°C (<18°C or >28°C)
Ohm Source (Accuracy is based upon 4W connection)
Range (Ω) | Excitation Current from Measurement Device | Accuracy (% of Output + Floor) |
1.0Ω to 400.0Ω | 0.5mA to 5mA | 0.015%+0.1Ω |
400.0Ω to 1500.0Ω | 0.05mA to 5mA | 0.015%+0.5Ω |
1500.0Ω to 4000.0Ω | 0.05mA to 5mA | 0.015%+0.5Ω |
4000.0Ω to 7000.0Ω | 0.05mA to 5mA | 0.03%+1Ω |
For 3W ohm source, assuming all three test leads are matched, add 0.05 Ω (0.00 Ω~400.00 Ω),
0.2 Ω (400.0 Ω~4000.0 Ω),and 1 Ω (4000.0Ω~7000.0Ω) to the specifications. Driving voltage<1.7V;
Temperature coefficient：±(0.002% of reading + 0.002% of range)/°C (<18°C or >28°C)
