The following is a list of the troubles that you may meet while using the

these troubles. If you still can‟t handle them, please contact
SIGLENT in time.
1. If the screen of the Multimeter is still dark with nothing displaying
after pressing the power key:
(1) Check if the power has been connected correctly.

The reading doesn’t change when connecting an AC current signal:
(1) Check if the test lead has been connected to the current jack or LO jack
correctly.
