7. Product description

The digital multimeter (DMM) displays measurements on a digital 4000-count display (count = smallest display value).
The display shows the correct terminal assignment for each measurement mode. The multimeter beeps and displays
a warning when the terminals are not assigned correctly. This is a built-in safety feature to protect the user.
The display also indicates the correct measurement terminals to use for each measurement mange.
The DMM switches off automatically after approximately 15 minutes if no buttons are pressed. This protects the bat-
teries and prolongs the battery life. The automatic power-off feature can be disabled.
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.
It is not necessary to replace a triggered fuse for mA/µA current measurements. The built-in PTC fuse restricts the cur-
rent flow in the event of an overflow to protect the multimeter and the circuit. The PTC fuse resets itself automatically
after a short cool-down phase, meaning that the current measurement circuit is only briefly interrupted.
The battery and fuse compartment can only be opened when all test leads have been disconnected from the multim-
eter. It is not possible to insert the test leads into the terminals when the battery and fuse compartment is open. This
is a built-in safety feature designed to protect the user.
Control dial (D)
Use the control dial to select the measurement mode. On the VC271TRMS, auto-
matic range selection ("Autorange") is enabled and the range will be automatically
selected. The measurement ranges must be selected manually. Always start with
the largest measurement range, and then switch to a smaller range if necessary.
The control dial features a function button (I). Use the "SELECT" button to switch
to a sub-mode when the measuring mode has more than one function (e.g. to
switch from resistance measurement to diode test or continuity test or from AC
to DC current). Press the "SELECT" button again to switch to the next sub-mode.
To turn the multimeter off, move the control dial to the "OFF" position. Always turn
the multimeter off when it is not in use.
