FLOWPULSE INSTRUCTION MANUAL
32
As an example, in an application with low flow through a 100 mm Pipe I.D.,
the user can choose to scale the mA output from 4 to 20 to correspond to a
flow range of 0 to 15 litres/sec instead of the full flow range of 0 to 31
litres/sec. This is achieved by first ensuring that the Pipe I.D. has been
correctly set, and then setting the Flow High limit to 15 (the Flow Low limit is
0 by default).
The mA Low and mA High setting can also be used to make small
adjustment to calibrate the device’s mA output at Flow Low limit and Flow
High limit. For example, if the mA output is 4.05 mA at Flow Low limit, the
mA Low setting can be set from 4.0 to 3.95 for calibrating the actual mA
output to 4.00 mA exactly.
mA Output: mA Trim
The mA trim allows calibration to the mA output by using a fixed mA offset.
The offset is in units of microamps (µA).
For example, if the mA output is 4.1 mA at Flow Low limit, an offset of minus
100 µA can be entered. Entering and saving -100 (minus 100) to mA Trim
would produce 4.0 mA at Flow Low limit.
The maximum offset allowed is ±500 µA (±0.5 mA). The mA trim should
only be used to make small offset to the mA output. This offset is applied
across the full mA range.
