4.4.2 20 mA SINK Function
The SINK function allows you to use DC current (DCmA) with the
polarity set to (minus). This allows drawing (SINK) the specified value of
the current from an external voltage source (distributor, etc.) in the direction
of the H terminal. Thus, you can use the instrument in a loop test, for
example, as a simulator for two wire transmitters.
☞Note
When using 20mA Sink function, prohibited the use of measurement
functions, otherwise it will cause damage to the calibrator.
