Scaling the 4-20 mA Analog Output (
Aout
)
The 4-20 mA analog output (if equipped) can be scaled to provide a 4-20 mA signal
for any display range selected for either the rate or the total.
No equipment is needed to scale the analog output; simply program the display
values to the corresponding mA output signal. The meter is factory calibrated for
milliamps.
The Analog Output menu is used to program the 4-20 mA output based on display
values.
For instructions on how to program
numeric values see Setting Numeric
Values, page 26.
!
CAUTION
Please note that when power is removed from the meter, the
analog output will remain at the last value transmitted at the
time of power loss. Take this effect into consideration when
designing any system using the 4-20 mA output.
