Specifications
The 787 ProcessMeter’s performance and accuracy are specified for one year after
calibration, at operating temperatures of +18 °C to +28 °C (64 °F to 82 °F), in relative
humidity to 90 %, after the ProcessMeter has been warmed up for 5 minutes.
Note
A “count” is the amount by which the least significant digit can vary.
