712B Specifications
712B Specifications
Specifications are based on a one year calibration cycle and apply from +18 °C
to +28 °C unless stated otherwise. All specifications assume a 5 minute warmup
period.

• Notes:
• Reading 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) to the specifications.
