15. ANALOG OUTPUT OPTION
An optional analog board may be installed in the meter at rear panel jack position J4, adjacent
to the signal conditioner board. Once installed, this board is recognized by the meter, which
will bring up the appropriate menu items for it. These will not be brought up if an analog output
board is not installed.
The analog output can be a 0-20 mA, 4-20 mA or 0-10V unipolar signal with respect to isolated
ground, or a bipolar -10V to +10V voltage signal with respect to a reference return line.
Unipolar or bipolar operation is selected by a jumper. A unipolar current or voltage output is
selected at the connector. Unipolar 4-20 mA or 0-20 mA current is selected in software.
Unipolar current of voltage: Jumper a
Bipolar -10 to +10 voltage: Jumper b
The low analog output (0 mA, 4 mA, 0V, or -10V) may be set to correspond to any low
displayed reading An Lo. The high analog output (20 mA, 0V or 10V) may be set to corres-
pond to any high displayed reading An Hi. The meter will then apply a straight line fit between
these two end points to provide an analog output scaled to the meter reading.
