First steps • Set-up the HART
®
device, if loop power required, use CH2 for
current (24V), see section 14.
• If the loop is already powered and there is an external HART
resistor turn off channel 2. Connect the channel 2 mA+ and
mA- connections across the external HART resistor. See section
14.3.
• If required, turn on the internal HART

information on the bottom left hand side of the screen as the
program executes.
• As the HART
®
application operates the DPI 620-IS finds the DD
associated with the device and all the parameters of the
HART
®
transmitter are collected and loaded into memory.
• A message box shows “Cannot find a device” if the device is not
connected. Refer to section 15.
First screen
• This is the first screen displayed by the instrument showing
