Method for automatically monitoring an electrical engineering workflow having a plurality of work steps, said method having the following steps: establishing (S0) a first bidirectional communication connection (F1) between a mobile communication device and a mobile voltage testing means (10; 10'); initiating (S1) a work step sequence program on a mobile communication device using an input means of the mobile communication device , outputting (S2), by way of the work step sequence program, a work step instruction (A) for enabling a voltage-carrying electronic component (K1) to make the electronic component (K1) voltage-free on an output means of the mobile communication device ; automatically or manually confirming (S3; S3') the enabling of the electronic component (K1) at the mobile communication device ; after confirming (S3; S3') the enabling of the electronic component (K1), outputting (S4), by way of the work step sequence program, a work step instruction (A) for checking that the electronic component (K1) is voltage-free using the mobile voltage testing means (10; 10') on the output means of the mobile communication device ; checking (S5) that the electronic component (K1) is voltage-free using the mobile voltage testing means (10; 10'); communicating (S6) the test result from the mobile voltage testing means (10; 10') to the mobile communication device ; if the test result indicates that there is no voltage, automatically confirming (S8) the check that the electronic component (K1) is voltage-free by outputting a confirmation signal by way of the mobile communication device ; if the test result does not indicate that there is no voltage, outputting (S9a) a first alarm signal by way of the mobile communication device . establishing (S0) a first bidirectional communication connection (F1) between a mobile communication device and a mobile voltage testing means (10; 10'); initiating (S1) a work step sequence program on a mobile communication device using an input means of the mobile communication device , outputting (S2), by way of the work step sequence program, a work step instruction (A) for enabling a voltage-carrying electronic component (K1) to make the electronic component (K1) voltage-free on an output means of the mobile communication device ; automatically or manually confirming (S3; S3') the enabling of the electronic component (K1) at the mobile communication device ; after confirming (S3; S3') the enabling of the electronic component (K1), outputting (S4), by way of the work step sequence program, a work step instruction (A) for checking that the electronic component (K1) is voltage-free using the mobile voltage testing means (10; 10') on the output means of the mobile communication device ; checking (S5) that the electronic component (K1) is voltage-free using the mobile voltage testing means (10; 10'); communicating (S6) the test result from the mobile voltage testing means (10; 10') to the mobile communication device ; if the test result indicates that there is no voltage, automatically confirming (S8) the check that the electronic component (K1) is voltage-free by outputting a confirmation signal by way of the mobile communication device ; if the test result does not indicate that there is no voltage, outputting (S9a) a first alarm signal by way of the mobile communication device . <EOS>
