See Figure A.1. 3.2 Maximum measurement time The maximum settable value of the measurement time depends on the type of component of the welding current meter. See Figure A.1. 3.3 The measured measurement time is indicated by measuring time The duration of the welding current from start to finish. Note. Normally, the start and end times used to measure the current are set automatically. If the start time is set to zero or a value greater than zero, the end The time is set at a value less than the welding time (see Figure A.1), the welding current is calculated by the measurement between the start time and the end time. 3.4 Automatic zero correction. Automaticzerolevelcorrection When measuring DC welding current, the effect of correcting the output zero drift on the device is allowed. ...... |
