Analog Scales HI SBA

Series

The ANY-WEIGH Analog Scale series come pre-cali-

brated from the factory. If additional dead load is per-

manently attached to the scale surface a recalibration

may need to be performed. All controls are accessible.

from the underside of the scale.

The ANY-WEIGH Analog Scale is calibrated at the

factory for 4 mA current output with zero millivolt

input and 20 mA output for 15 mV input. In some

cases, the transmitter will require a very simple recali

bration to the system in which it is installed. The cali-

bration procedure provided in this section is designed

to be used either in new installations or for recalibra

tion of existing systems. Make sure that you read the

Calibration Controls Section before calibrating the

transmitter.

Calibration

Controls

Coarse (ZERO) The Coarse Control is used to remove large dead

loads or offsets such as the weight of a container, and/

or any other constant weight on the scale which is part

of the weighing equipment itself. This control can

subtract as much as 65% of full scale from the output.

Fine (ZERO) This control is a fine offset adjustment. Its range is

sufficient to fine tune the Coarse adjustment.

Span This control adjusts the gain of the scale. It deter-

mines how many millivolts (of transducer signal) per
