B. Analog Output

The zero point (4mA) and span point (20mA) of the analog out-

put can be set in the range of 10 to 110%F.S. of the maximum

display span (between OFFSET and FULL SCALE).The span

between the zero point and the span point in this analog output

is the linear display span.

• As shown in the graph on the left, the OFFSET is set as Out-

put zero point (4mA) and the FULL SCALE is set as Output

span point (20mA), but the OFFSET can be reversed to Out-

put span point (20mA) and the FULL SCALE can be reversed

to Output zero point (4mA).

Setting Example 2 : Linear Display Mode

In this example the desire of the user is to use the GC51 as a “load

meter” with the arbitrary unit being “ton”. Using a pressure range of

0 to 100psi, Setting Mode to display the OFFSET for minimum

pressure 10psi as 0.00, the FULL SCALE for maximum pressure

60psi as 5.00, the unit as arbitrary unit (ton), the zero point (4mA)

of analog output as 0.00, and the span point (20mA) as 5.00 is

as follows.

FURTHER DETAIL regarding menu and button sequence is shown

in Section 13.3.
