battery case and close the multimeter carefully and reinstall the
screws with a screw driver.
Attention!
Never use the measuring unit before the cover has been closed
completely. Life Danger!
Never leave empty batteries in the measuring unit, as even
corrosion-free batteries might leak and chemicals could be
released, which are detrimental to your health and may disturb
the battery compartment.
Please remember used batteries - due to their heavy metal
content - are no ordinary refuse. They must be disposed of in
special containers (collecting points) or in a safe manner that
complies with all applicable laws.
4.2 Connection of the Measuring Cables
For measurement use only those test leads which are supplied with
the measuring unit. Only these are admissible.
Ensure the connection plugs and test probes are in good condition
before usage, pay attention that the insulation is undamaged.
These measuring cables are permissible for voltages up to 750 V max.
Your measuring unit Voltcraft 227, is rated for voltages of max 750
VDC/VACrms. Use special caution when working with voltage above
25 V AC and above 35 V DC.
Attention!
Never exceed the max. input limits, as under unfavourable
circumstances this could be life dangerous.
4.3 Operation
4.3.1
Basic Settings
To select a function, turn the rotary function switch to the desired
position ("V" or "Hz" etc.) With the blue key (1) the unit can be
switched on and off.
4.3.2
Special Functions
a) Manual Range Selection
Attention!
This help function is not possible for the logic test and diode
test, continuity check and during frequency measurement (Hz).
Set the rotary function switch to one of the four remaining measuring
functions "V", "Ohm", "Hz" or "
" = capacity measurement.
Press the key "
" once. The respective symbol appears on the left
side of the display. Now you can set any desired measuring range e.g.
during capacitane measurement, e.g. to select capacitors with a
certain capacity (0.001
µ
F to 10000
µ
F).
To leave this function press the key "
" for more than 1 second or
turn the rotary function switch.
The respective symbol will disappear from the display and the
multimeter is again in the autorange mode.
b) MIN-MAX Recording Function
Attention!
This help function can only be used during volt measurement or
resistance measurement.
