 Once the step function is defi ned, set the switch
to Adj. Step and select Step Function n°3 using
the or key.
 Start the measurement by pressing START/

 At the end of the measurement, the following results are indicated:
the difference   R in insulation resistance between the resistance at the highest test voltage

and the resistance at the lowest test voltage,
the difference   V between the highest and lowest test voltage,

the slope of the curve in ppm/V,

 the capacitance.
 Pressing the GRAPH key displays the resistance versus time curve.
Using the and keys, it is possible to move along the curves and view the exact values of each
sample.
