Configuration Controls
Software Configuration Only via USB/Windows or USB-OTG/Android & Agility
This dual transmitter modulates the level of analog output current in separate 2-wire
current loops proportional to their sensor inputs based on its differential voltage
measurement across its input at TB1 and TB3. No switches or potentiometers are
used to make adjustment to this transmitter. Its behavior as an isolated signal
amplifier/transducer is determined via programmed variables set using a temporary
USB connection to a host computer or laptop running a Windows-compatible
configuration software program specific to the transmitter model, or a wired USB-
OTG connection to an Android smartphone or tablet running Agility. The USB
software or Agility app provides the framework for digital control of all configuration
and calibration parameters, which are stored in non-volatile memory of the unit.
LED Indicators, Red FLT1 & FLT2
One Red FLT LED per output current loop. Blinking red continuously indicates the
corresponding output load resistance is too high to drive its current accurately, or
the loop voltage level is too low to drive the loop resistance at the desired current
level. OFF is normal and LED will blink once if loop power is lost or the loop is
opened.
