Product Description; Display Indications And Symbols - VOLTCRAFT VC-420 Bedienungsanleitung

7. PRODUCT DESCRIPTION

The multimeter (referred to as DMM in the following) indicates measured values on the digital display. The measured
value display of the DMM comprises 6000 counts (count = smallest display value). The AC measurement for voltage
and current is performed as an effective median value (TrueRMS).
If the DMM is not operated for approx. 15 minutes, it switches off automatically. This saves battery power and extends
the period of operation. Automatic deactivation can be deactivate manually.
The meter can be used for do-it-yourself or for professional applications up to CAT IV. The moulded-on rubber protec-
tion makes the device extremely robust, enabling it to survive even a fall from 2 m height. The device is also dust- and
water-tight (IP67). The rubber seal in the battery compartment must be regreased with silicone grease at a battery or
fuse change to ensure tightness.
There are transport protection caps in the angled plugs of the enclosed measuring lines. Remove them before pushing
the plugs into the meter sockets.
For better readability, the DMM can also be optimally mounted with the standing bracket on the rear.
Dial switch (3)
The individual measuring functions are selected via a rotary control. The automatic
range selection "AUTO" is active for most measuring functions. The appropriate
measurement range is set individually for each application.
The dial switch has several functions in some areas. These subfunctions can be
switched with the button "MODE" (e.g. switching resistance measurement for diode
test and continuity test or AC/DC switching in the current range, etc.). Each push
switches the function.
If the meter switch is set to "OFF", the meter is switched off. Always turn the meter
off when it is not in use.
