7. OVERVIEW
The multimeter (referred to as DMM in the following) indicates measured values on a digital display.
The measured value display of the DMM comprises 40000 counts (count = smallest display value).
If the DMM is not operated for approx. 15 minutes, the device switches off automatically to save
power. This function will work only if the DMM is powered by batteries. Automatic switching off is
deactivated when the interface is switched on.
The meter can be used for do-it-yourself or for professional applications up to CAT II.
Only in the voltage / current measurement area, a warning sound and a
fl
ashing “WARNING!” signal
is used to announce incorrectly connected measuring leads. Connect the measuring leads correctly
before measuring.
The individual measuring functions are selected via a rotary control. The automatic range selection
“AUTO” is active for some measuring functions. The appropriate range of measurement is set
individually for each application. Always start current measurements at the highest measurement
range (10 A) and switch down to lower ranges if necessary.
The power switch (22) at the back is for turning the product on / off. Always turn the product off when
it is not in use.
The compartment at the top of the device is used for stowing cables and measuring leads.
