SPAN (Span Calibration Routine)
13.2. Performing a Calibration with Direct mV/V Entry
In applications where test weights are not easily available, it is possible to calibrate
the instrument directly by entering the mV/V signal strength at Zero and Span. The
Direct Zero setting (SCALE:CAL:DIR.ZER) specifies a gross zero point for the scale.
The Direct Span setting (SCALE:CAL:DIR.SPN) specifies the mV/V signal strength
corresponding to an applied mass. This calibration technique is not compatible with
linearisation. Clearly the accuracy of this type of calibration is limited to the
accuracy of the direct mV/V data.
13.2.1.
DIR.ZER (Direct Zero Calibration Entry)
Press the
<OK>
key to start. The display will show the current weight.
Press the
<OK>
key. Change the mV/V setting to the correct value for Zero and
press the
<OK>
key.
DONE
will be displayed along with the weight to allow the
reading to be checked.
Press the
<OK>
to leave the zero routine.
13.2.2.
DIR.SPN (Direct Span Calibration Entry)
Press the
<OK>
key to start. The display will show the current weight.
Press the
<OK>
key. Change the weight to the correct value and press the
<OK>
