1. Connect the instrument to the pressure standard (Figure 2).
2. Let the equipment get to a stable temperature (minimum: 30 minutes since the last power
on).
3. Use the calibration menu (Table 6) to do a two-point calibration (Zero and +FS) or a three-
point calibration (-FS, Zero and +FS). Refer to Table 7. The display shows the applicable
instructions to complete the calibration.
