User manual

7. Product description

The multimeter (DMM) displays measurements on a digital display. The multimeter has 6000 counts (count = smallest

display value). The correct socket assignment is displayed according to the measurement mode selected. Incorrect

socket assignment is indicated by a warning sound and warning indicator. This increases the operational safety of

the multimeter for the user.

If the DMM is not operated for approx. 15 minutes, the device switches off automatically. This saves battery power and

extends the period of operation. The automatic shut-off feature can be disabled manually.

The DMM can be used to take measurements up to CAT III 600 V. It is suitable for use in hobby and professional

applications.

The DMM can be placed on a level surface using the fold-out stand for better readability.

With this multimeter, it is no longer necessary to replace a fuse that has accidentally tripped in the mA/µA measure-

mentrange.Thebuilt-inPTCprotectionelementslimitcurrentowintheeventofanoverloadandthusprotectthe

An external clamp transformer allows direct and alternating currents of up to 60 A to be measured contactlessly

without interrupting the current circuit. The measurement input is equipped with a maintenance-free PTC protection

element to protect against overload.

The battery and fuse compartment can only be opened when all test leads have been removed from the multimeter.

When the battery and fuse compartment are open, the test leads cannot be inserted into the measurement sockets.

This is a built-in safety feature designed to protect the user.

Rotary control (D)

The individual measurement modes are selected via a rotary

control. On the VC281TRMS, automatic range selection “Auto”

is enabled. This means that the appropriate measurement

range is set automatically. The current measurement ranges

must be set manually. Always start with the largest measure-

ment range, and then switch to a smaller range if necessary.

The rotary control has a mode button (I). With the “SELECT”

button, you can switch to a sub-mode if the measurement mode

is double assigned (e.g. switching resistance measuring - di-

ode test and continuity test or AC/DC switching in the current

range). Press the “SELECT” button again to switch to the next

sub-mode.

To switch the multimeter off, move the rotary control to the “OFF”

position. Always switch the multimeter off when it is not in use.
