4.3.2 Scaling Without Known Loads

To scale without known inputs, calculate input values based on the transducer
specifications and manually enter them on the front-panel pushbuttons. The following
example assumes a pressure transducer with these specifications:

Pressure Range: 0 to 2000 PSI

Output Span: 1 to 5 Vdc

1. Determine the correct values for IN1 and IN!2 based on the transducer
specifications. In most cases, RD1 & RD!2 are equal to the minimum and
maximum of the transducer output span. The example assumes RD1 & RD!2 are
equal to the pressure range of the transducer (RD1 = 0000 and RD!2 = 2000).
Calculate IN1 and IN!2 using the transducer output span and the following

equation:

IN = (Sensor Output) x (Natural Gain) x (Multiplier).

Table 4-3. Natural Gain

2. Determine the multiplier by the Input Resolution setting (R.2 in the RD.CF menu)
and the input range selected. Typically R.2=4 is suitable for most applications.

Table 4-4. Input Resolution Multiplier

Input Range R.2=4 R.2=3 R.2=2 R.2=1 R.2=0

4.11 SELECTING PROPORTIONAL BAND P.BND

Proportional Band P.BND is not active unless your meter has analog output and relay
capabilities. The menu will display whether analog output is present or not.

• A proportional controller's output is linearly proportional to the change of the
error signal, whenever the signal is within 2 prescribed values (Proportional
Band).

• There are three (3) points of interest on the proportional controller transfer
curve.

• The first is the magnitude of the error signal that drives the controller to
“full on

” (e.g. 20 mA out for 4-20 mA).

Figure 4-2. Controller Output

• The second point of interest is the magnitude of the error signal that drives
the controller output to “full off” (e.g. 4 mA out on 4-20 mA). These two (2)
points need not be equally spaced on either side of the zero error point.

• The third is the factor "Offset" and it is the output value of the
controller which causes zero error.

The above example illustrates the parameters for the 4-20 mA analog out,
likewise, analog voltage output will have these (3) points of interest.
