again to display a screen like
. The displayed value is “counts” --
not mA -- that dynamically change as the output is ad-
justed.
6.
Connect a calibrated digital multimeter in series with
the loop load to measure the actual minimum mA output
in the loop.
7.
Use
arrow keys
to adjust the minimum output value to
read exactly “4.00 mA” on the digital multimeter -- not
the transmitter display, and press
ENTER key
to com-
plete calibration of the minimum endpoint value.

is “counts” -- not mA -- that dynamically change as the
output is adjusted.
10. Now measure the actual maximum mA output in the
loop with the digital multimeter.
11. Use
arrow keys
to adjust the maximum output value to
read exactly “20.00 mA” on the digital multimeter -- not
