6) Check that the displayed value corresponds to that set on
the ISO-Kalibrator 1, taking into account the tolerances of
the insulation meter. In critical cases, you should use the
true value listed in the test protocol of your ISO-Kalibrator 1
as comparison value.
7) Conclude the measurement and put the ISO-Kalibrator 1
into an electrically dead condition.
8) You now can select another test resistor and start a new
measurement, or disconnect the insulation meter from the
ISO-Kalibrator 1.
9) Do not on any account switch resistors over in live condi-
tion.
No test resistor is active when the ISO-Kalibrator 1 is set to the
"OFF" position. In this case, your insulation meter should indi-
cate overrange, or at least show an insulation resistance of
>1G, provided it permits the measurement of insulation
resistances with several G.
