■ LOW
In the LOW mode, the insulation resistance of the test leadwire and jigs is included
in measurements, as shown in Fig. 5-7 (A) and (B). However, the ammeter is pro-
tected from short-circuiting, ensuring safe testing regardless of whether the DUT is
grounded. For this reason, it is recommended that LOW be set in ordinary tests.
