    Issue 1 10.14 Procedures: 1. Assemble the pressure indicator with the necessary PM 620-IS modules and connect the instrument to the Pressure indicator pressure standard; see Section 4.4.4 (Example procedure: modules (PM 620-IS) Measure pressure). 2. Let the equipment get to a stable temperature (minimum: 60 minutes since the last power on).

Make sure the error is in the specified limits; see the tables for Gauge Ranges or Absolute Ranges given in the datasheet (supplied on the CD: P/N UD-0002); use the values in column “Total uncertainty ... “. The specified values include an allowance for temperature changes, reading stability for one year, and the uncertainty of the standard used for calibration.
