7.3: Configuring Option Cards
CAUTION! FOR PROPER OPERATION, RESET ALL PARAMETERS IN THE UNIT
AFTER HARDWARE MODIFICATION.
The Shark® 200 meter auto-detects any Option cards installed in it. You configure the
Option cards through Communicator EXT
TM
software. Refer to Chapter 5 of the
Communicator EXT
TM
User Manual for detailed instructions.
The following sections describe the available Option cards.
7.4: 1mA Output Card (1mAOS)
The 1mA card transmits a standardized bi-directional 0-1mA signal. This signal is
linearly proportional to real-time quantities measured by the Shark® 200 meter. The
outputs are electrically isolated from the main unit.
