Hi
I want to use 5081-A Transmitter along with 499ATrDO Dissolved oxygen sensor.
Our required calibrated range is 0-20 ppb.
In the transmitter 5081 datasheet (LIQ_PDS_5081/Rev.R Page#6) under the heading of General Specifications for 5081-A, it is defined as following:
Repeatibility (Input) = 0.1% of range
Linearity (input)= 0.3% of range
and above some input ranges are given in current units.
Now, we know that the sensor 499ATrDO has the range of 0.1 to 20 ppm (i.e. 20,000 ppb), so does it meant that the repeatability of the transmitter will be 0.1% of 20,000 ppb? and similarly linearity will be 0.3% of 20,000 ppb? This will result in a very high values for repeatability and linearity as our working range is only 20 ppb. Can you please explain this doubt?
