Intermediate level
ranges are available. |
|
(2) | Total Error Band (TEB) includes the combined errors due to nonlinearity, hysteresis, nonrepeatability and thermal effects over the compensated temperature range per ISA S51.1. |
| (3) |
For absolute reference, additional error up to ±0.2% FS/year may be incurred due to offset drift. |
| (4) |
For sampling rates greater than 3 Hz, the pressure/temperature averaging must be reduced as required. |
| (5) |
An external battery with 2300 mAh capacity, sampling 4 times/hour, will allow datalogging for 1 year. |
