Requirement(s)
• 10 Ω/90 W (for U8001A)
)
L
• 6 Ω/150 W (for U8002A)
• 0.01 Ω ± 0.1%
• TCR less than 20 ppm/ºC
For optimum performance, all procedures should comply with
the following recommendations:
• Assure that the calibration ambient temperature is stable
and between 20 °C and 30 °C. Ideally the calibration should
be performed at 25 °C ±1 °C.
• Assure ambient relative humidity is less than 80%.
• Allow one hour warm up period by power on the power
supply. During warm up period, set the power supply to
maximum programmable voltage and current. Then, enable
the output.
• Keep the test setup connection cables as short as possible.
