7.1.2 Safety Precautions
1. Use an AC power supply with the specified voltage.
2. Execute calibration under the following conditions in a location free of dust, vibration, noise or other
adverse conditions:
6146: Temperature 23°C ±3°C Relative humidity 70% or lower
6156: Temperature 23°C ±1°C Relative humidity 70% or lower
3. Allow the 6146/6156 to warm-up for 2 hours or longer before calibration.
Allow the measuring instrument to be used in calibration to warm-up for the period of time specified
before the calibration.
4. After calibration, note the dates of the calibration and the next scheduled calibration on a card or
sticker, etc. for convenience.
5. The DAC calibration function is included in the 6156 only.
6. When executing DAC calibration, be sure to execute voltage source calibration and current source
calibration after that.
7. For DAC calibration, use DMM whose linearity of from 0 V to 3 V is within 0.5 μV.
8. Connect the measuring instruments to be used in calibration in accordance with Section 7.1.3, "Con-
nections." Improper connections may cause incorrect calibration or malfunctions.
