• The measured values are displayed on the LCD display.
• If a too low measuring range that is being exceeded during measuring is being
selected manually, "OL" appears on the display. Then, please select a higher
measuring range.
• With the input jack of 200 mA, the max. input current should not exceed
200 mA as an overvoltage may damage the fuse. With a higher current, the
input jack 10 A for max. 10 A input current needs to be used.

Measuring electrical resistance
Attention! Make sure when measuring internal resistance that the about to be
n or measured object is volt-free and that all capacitors are fully discharged.
h the • Connect the black measurement line to the ground jack COM and the red line
to the input jack.
CD • Turn the selector switch to the measuring range
range manually with the help of the RAN button or use the pre-set automatic
being measuring range option.
er • Connect the measurement lines for measuring the resistance parallel to the
measured resistance.
• The measured values are displayed on the LCD display.
he • With a disconnection of the measuring circuit, the symbol "OL" appears on
the display. With this, the transgression of the measuring range value is being
indicated.
Please note! During the measuring of a resistance, a slight deviating value to
the data of the resistance can be displayed as the test current of the Multimeter
runs parallel to the measured circuit. To increase the accuracy during measuring
smaller resistances, connect both of the measurement lines short-time at first and
note down the value. Afterwards, subtract the value from the value of the actual
resistance measurement.
