LOW
In the LOW mode, the current which flows through the LOW terminal by insulation
resistance of the test leadwire and jigs is included in the measurements, as shown in
Fig. 5-3 (A) and (B). However, the ammeter is protected from short-circuiting,
thereby ensuring safe testing regardless of whether the DUT is grounded. For this
reason, it is recommended that LOW be set in ordinary tests.
