3 MODEL: MEXM EXTERNAL IEW PERCENT % OUTPUT Up Button Mode Button SW Down Button Up Down Mode Set Set Button Configurator Jack ON OFF Output Setting DIP SW ON SW OFF COMPONENT Mode Button Set Button Up Button Down Button Confi gurator Jack FUNCTION Indicates present values, setting values and abnormal information. Two types of present values at upper and lower are displayed by setting. Used to shift from measuring mode to each setting mode. Destination to shift is changed by the time pressing and holding the button. Used to return from each setting mode to measuring mode. (press and hold for sec. or more) Used to change setting value of setting parameter. When at setting changeable state, used to enter (save) the setting value. Used to move on through digits of setting value for input/output scaling at setting changeable state, Used to shift through setting parameter, and to increase or select setting value. Used to shift through setting parameter, and to decrease or select setting value. Used to confi gure with ME confi gurator software (model: MECFG). At the same time, set the lockout setting of the unit to lock. Refer to the operating manual (EM--B) for detailed procedures. MEXM SPECIFICATIONS ES- Rev. Page /
