SEQUENCE VERIFICATION
WARNING
The maximum DC or AC+DC input voltage is 1000V. When the display
shows “> 999.9V”, it means that the maximum value the clamp is able to
measure has been exceeded. Exceeding these limits could result in
electrical shocks to the user and damage to the instrument.
By positioning the selector switch to “V ”, the screen to the side
will appear.
