Setra Micro-Cal 869 Specifications

Accuracy

● Highest accuracy to support certification of all low DP critical process pressure sensors

● True low range dual reference pressure sensors with NIST traceability

● Dual reference design provides maximum accuracy, repeatability and resolution

Pressure Generation

■ User selectable automated pressure generation profiles with up to 101 calibration points

■ NASA patented low pressure generating technology achieves ±0.0002 in. W.C. low

pressure regulation - micro in. of W.C. per step resolution

■ True differential pressure generation - both high and low pressure ports connect to the
unit under test, providing isolation from process background disturbances

■ True zero pressure generation - high and low pressure ports shorted to produce stable,
noise-free zero pressure input - outperforms competitive active zero pressure systems
