A current value set switch 235 in an operating section 23 is then depressed to set a current value setting mode. When a current value is set by means of a ten key 231 and a set switch 234 is depressed, thus set current value is read in and subjected to validity judgment. If it is valid, data in a memory 31 are updated while furthermore indication data are also updated and displayed on a set current value display section 241 at all times during monitoring mode. |
