Display

A 2 line, 16 character, display
providing all visual user feedback for
the isolated input operations. See
section 2.6 for layout details, and
section 2.7 for possible error
messages.

Function keys

Select DC voltage and current input
mode.  Subsequent presses of this
key cycle through the ranges: 10V,
100V, and 50mA.

When using 50mA mode to test a 2
wire loop powered transmitter that is
disconnected from its wiring, press
this key to activate an internal 24V
power supply in series with the current
measuring circuit.  Press the key
again to deactivate the 24V supply.

When using 50mA mode to test a
HART configuration device, press
this key to activate an internal 250
ohm resistor in series.  Press the
