Scaling and Calibration

The controller provides offset calibration for thermocouple,
RTD, and other fixed ranges, and offset and span (gain) cal-
ibration for linear and pulse inputs. In order to scale linear
input signals, you must:

1.

Install appropriate scaling resistors. (Contact Watlow
Anafaze’s Customer Service Department for more in-
formation about installing scaling resistors.)

2.

Select the display format. The smallest possible range
is -.9999 to +3.0000; the largest possible range is
-9,999 to 30,000.

3.

Enter the appropriate scaling values for your process.

Configuring Dual DAC Outputs

Dual DAC modules ship with both outputs configured for
the signal type and span ordered. The module contains two
independent circuits (DAC1 and DAC2). These circuits can
be configured for different output types. Remove the board
from the housing and set the jumpers. The odd numbered
jumpers determine the signal from DAC1; the even num-
bered jumpers determine the output from DAC2.
