Caution
Use an antistatic work surface and wrist strap to lessen the
chance of electrostatic discharge.
1. Measure the temperature and humidity of the environment and write the
values on the "Performance llest Record." The performance is specified
at an ambient temperature of +23OC f3O. Therefore, the environmental
measurement calibration has been done, the ambient temperature must be
held to fl°C.
2. Open the calibration and verification kits and place all the devices on top
of the foam so they will reach room temperature. TEMPEBATUBE OF
TEE DEVICES IS IMPOE'MNT because device dimensions (electrical
characteristics) change with temperature.
Switch on the power to the instrument.
3.
Note
to warm up for at least 1 hour
achieve the maximum system stability, allow the instrument
