Today, instrument maintenance
is moving out of the shop and
into the field. This reduces
process interruptions and
avoids the time and expense
of returning instruments to the
shop. Portable communicators
and calibrators are often used
together to complete field cali-
brations. However, the desire to
carry less equipment and to per-
form maintenance in the field
has created a need for a new
class of calibration tool.
The new 754 Documenting
Process Calibrator from Fluke
is a powerful yet easy-to-use
tool for field calibration of HART
instrumentation. Pressing a
single key enters the HART
mode and displays the essential
HART information in the Active
Device Screen, shown in Figure
2. Additional HART functional-
ity is accessed with only a few
more keystrokes, per the menu
tree in Figure 3.
