FS vs Reading Explained

There is a difference:

ASM1300PG2M1103A00  the "A" indicates the accuracy is ±0.05%FS (±0.15 psi). This means that no data point will be off greater than 0.15 psi.

ASM1300PG2M1103B00  the "B" indicates the accuracy is ±0.1% Reading. Results will be better in all pressures < 150 psi

Error @ 0.05%FS Pressure Error at 0.1% Reading

0.15 psi 30 psi 0.03 psi

0.15 psi 100 psi 0.10 psi

0.15 psi 150 psi 0.15 psi

0.15 psi 200 psi 0.20 psi

0.15 psi 300 psi 0.30 psi

Either method will have a Total Error Band < ±0.25% (±0.75 psi)
