4.9.1 Calibration Method for External Monitoring Equipment
When the CAL switch on the SAN unit display is pressed, load voltage is outputted on the LOAD
OUT at a potential difference of approximately 2.5V. The load value which the SAN unit
recognizes at this time is displayed on the DATA display.
Make adjustments so that the load value that is displayed at this load voltage is the same as the
external monitoring equipment.
* The load voltage at zero load is not 0V.
The load voltage depends on the tool therefore, correction for zero point is required by external
monitoring equipment.
