device operations K0460 - [EN] English
2. Set-up the HART
®
device, if loop power required, use CH2 for
current (24V).
If the loop is already powered and there is an external HART
®
resistor, turn off CH2. Connect CH2 mA+ and mA- connections
to the HART
®
resistor, see Section 1.3.
If required, turn on the internal HART
®
resistor. This can be
selected by pressing icon.
Press the HART
®
button and the application starts.
3. Complete the electrical connections and continue with the
HART
®
menu operation; see Section 8.4.
4. Complete the electrical connections and continue with the
HART
®
menu operation; see Section 8.4.
