Jumper Settings
The loop current can be selected with the on-board jumper
plugs. Several output ranges, such as 0 to 20 mA, 4 to
20 mA, 0 to 10 mA, 2 to 10 mA, 0 to 5 mA, and 1 to 5 mA,
are available as user configurable options, each with
factory-adjusted zero and span levels. The voltage-mode
signals are easily obtained by connecting a suitable resistor
across the readout device's terminals. Signal full scale
options are also available. For instance, a directional scale
of 540° (0-360-180°), which is convenient for analog panel
meters or chart recorders, can be chosen to prevent the
needle or pen from oscillating across the scale with
northerly winds.
