, refer to section18)
The (V-E) calculated value may become 0.1 or lower due to errors in the sensor's output voltage
and errors with the measuring instrument. If it falls below 0.1 in this manner, we recommend
rounding up to 0.1 and calculating.
Condition Measured output voltage
In normal measurement Voltage corresponding to the measured pressure
When measurable higher limit is exceeded 5.1 V
When lower than measurable lower limit 0 V
When filament has burnt out 9 V or higher
