Button functions
FUNC – function button for selecting measuring mode:
When you are
measuring current or voltage, you can switch with the “FUNC” button in
between direct and alternating current measurement or direct and alternating
voltage measurement. With temperature measurements, you can switch with the
“FUNC” button between °C and °F. With the diodes and continuity checks, you
can as well switch with “FUNC” between them.
HOLD – measurement storage:
If you want to safe a measured value, please
push the “HOLD” button. The symbol “DATA-H” appears on the display, the
saved measured value is constantly displayed on the display. Pressing the button
again, the measured value saving is being made void and the present value is
being displayed.
RAN – range conversion:
The automatic measuring range is being used with
current-, voltage- and resistance measurements. Press the button “RAN” if a
manual measuring range option is desired. Every actuating of the “RAN” button
raises the measuring range. If the highest measuring range is reached, with
pressing the button again, it starts with the lowest measuring range again. If
you press the “RAN” button for more than 2 seconds, the automatic measuring
range is being activated again.
NCV find contactless voltage source:
Hold down the “NCV” button and
move the Multimeter within the range of the about to be tested range. Very
sensibly, the device indicates a possible voltage source with an acoustic signal
and a flashing of the LED above the display. This function can be applied to every
mode.
Measuring of direct current voltage
Attention!
Input voltages over 600 V DC cannot be measured. Higher input
voltages can lead to personal damages and / or to damages of the device.
Be sure not to get an electric shock while measuring.
• Connect the black measurement line to the ground jack COM and the
red measurement line to the input jack.
• Switch the selector switch to the voltage range. Determine the measuring
range manually with the help of the RAN button or use the pre-set automatic
measuring range option.
• Connect the measurement lines for measuring voltage parallel to the voltage
source.
• The polarity of the red measurement line connection is displayed on the LC
display.
• If a too low measuring range that is being exceeded during measuring is being
selected, “OL” appears on the display. Then, please select a higher measuring
range.
• With choosing a low measuring range and open measurement lines,
“measured values” might be displayed through electric interfering fields. As
soon as the measurement lines are being connected with the measured object,
real measured values are being displayed.
Measuring of alternating voltage
Attention!
Input voltages over 600 V AC rms cannot be measured. Higher
measuring ranges can lead to personal damages and/or to damages of
the device. Be sure not to receive an electric shock during high-voltage
measurements.
• Connect the black measurement line to the ground jack COM and the
red measurement line to the input jack.
• With the selecting switch, select the voltage range. Press the “FUNC” button
to choose the alternating voltage measurement. Determine the measuring
range manually with the help of the RAN button or use the pre-set automatic
measuring range option.
• Connect the measurement lines for measuring voltage parallel to the voltage
source.
• The measured values are being displayed on the LC display.
• If a too low measuring range that is being exceeded during measuring is being
selected, “OL” appears on the display. Then, please select a higher measuring
range.
• With choosing a low measuring range and open measurement lines,
“measured values” might be displayed through electric interfering fields. As
soon as the measurement lines are being connected with the measured object,
real measured values are being displayed.
