15. SINGLE & DUAL ANALOG OUTPUT OPTIONS
Two versions of an 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.
A single analog output version
can be configured for unipolar 4-20 mA current, 0-20 mA
current or 0-10V voltage, or bipolar -10 to +10V voltage (with a 20V voltage swing). Unipolar or
bipolar operation is selected by a jumper.
A dual analog output version
can be configured for two unipolar outputs, which can each be
4-20 mA, 0-20 mA or 0-10V. Current or voltage output is selected at each connector.
Unipolar current or voltage: Jumper
a
Bipolar -10 to +10 voltage: Jumper
b
No jumpers, only selections at the connectors.
With either board,
current or voltage output is selected at the connector and in the Menu. The
low analog output (0 mA, 4 mA, 0V, or -10V) may be set to correspond to any low displayed
reading

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. The decimal point location
is fixed by the
dEC.Pt1
selection.
