2. Use of the device
1. Check the 9 V battery, turn Power On position. If the battery exhausted, the
2. The signs next to the wires are showing, that the input voltage or current shouldn't be higher than the correct value. In this way you can
protect the internal circuits from the damages.
3. Please, turn the Function switch in to the right position(function).
4. If you don't know the range of the measuring value, choose the largest range and do it backwards till you find the right one.
2.1 DC and AC voltage measurement
1. Connect the black wire to the "COM", and the red wire to the "V/Ω/Hz plug.
2. Turn the Function switch in to the right V position and connect the wires parallel with the voltage source for the measuring time.
2.1.1 Phase searching function
1. Turn the Function switch to the "TEST" position, connect the red wire to the "V/Ω/Hz" socket. A sound and a(flash)light will indicate if
there is phase.
Note:
a. If you don't know the measured current range, turn the Function button in to choose the largest range and do it backwards till you find
the right one by switching it down .If the "1" or the "-1" appear on the display, that means overload. In this case turn the Function
switch into a higher measure range.
b. Don't connect higher then DC1000V/AC7000V RMS voltage to the input .
c. Don't touch the high voltage current during the measure.
