After the last point is established, the Model 370/375 will prompt with Cal ~ Good? Press the
[TARE] or [SAMPLE/Enter] key to accept the calibration or press [ZERO] or [CLR] to backup
and redo the last point as described below.
If you make a mistake at any point in the linearization process, simply press the [ZERO] or [CLR]
key. The Model 370/375 w backup one step in the procedure to the previous linearization point.
After the linearization has been completed, the changes must be saved by pressing [TARE] or
[SAMPLE/Enter] at the Enter = Save prompt. Otherwise the previous calibration data will remain
in effect.

Once a zero reference has been established, the Model 370/375 displays Enter ~ Load and
awaits the entry of a span (test load) value. This value may be entered before or after the test
load has been applied.
If the calibration weight value was entered before applying the test weight, Add ~ Load is
displayed indicating that the test weight should now be applied. Apply the test weight, press
[TARE] or [SAMPLE/Enter] and proceed to Exiting Calibration on page 71.
If it is necessary to repeat the calibration process, press [ZERO] at the Cal ~ Good? prompt and
repeat the calibration process.
Establishing span with a 100lb test weight:
1. Place a 100lb test weight on scale.
