When the measurement current is switched, zero-adjustment will be initialized. Perform
zero adjustment again.
•
When using the INT trigger source, current will stop when a contact error occurs (when
not connected to the measurement target). By contrast, when using the INT trigger
source with the contact check function off, the measurement current is always applied,
even when the instrument is not connected to the measurement target. Consequently, a
rush current will flow at the moment the instrument is connected to the target (for exam-
ple, measuring a pure resistance in the 1 A measurement current range will result in a
maximum current of 5 A with a convergence time of 0.5 ms). When measuring easily
damaged elements, either turn on the contact check or use a range that results in a low
measurement current. However, if there is chatter even when the contact check is
enabled, it will not be possible to completely prevent a rush current.
