The digital multimeter (DMM) displays measurements on a backlit digital display. The DMM has a 4000-count display
(count = smallest display value). The display can display values from 0 to 3999.
The VC-522 is designed to measure alternating currents of up to 400 A.
The VC-523/VC-523 SE is designed to measure direct and alternating current of up to 400 A.
The multimeter switches off automatically after a period of inactivity. This protects the batteries and extends the bat-
tery life. The automatic power-off feature can be disabled.
The DMM can be used to take measurements up to CAT III. It is suitable for use in hobby workshops and professional
applications.
Protective caps may be attached to the angled test lead plugs. Remove these before inserting the test leads into the
multimeter.
Rotary dial (F)
The measurement modes are selected using the rotary dial. Automatic range selection ("AUTO") is enabled in some
measurement modes. This sets the measurement range automatically.
To turn the multimeter off, move the control dial to the "OFF" position. Always turn the multimeter off when it is not in
use.
