*1.
V M AC
Only normally measured signals are applied to Max and Min values. Values during scaling errors are not. Values
other than in normal measuring conditions are indefinite.
*2. Display value, Max value, Min value and Analog output are indefinite during the infrared communication mode.
*3. Analog output is valid only when the device status code for the analog output equals ‘1.’ It is indefinite when the code equals
‘0.’
