High Resistance Decade Calibration of insulation meters and megaohm meters 4 decades Range 1 MΩ – 12 GΩ Maximum working voltage 5 kV DC Internal accumulator / power line adapter Serial interface RS232 control High resistance decade box is aimed for calibrating of insulation meters and megaohm-meters. It is suitable for calibration laboratories and service centers, where it can be used also for testing or setting of high resistance meters. High voltage relays with extremely high insulation resistance are used for switching of resistance components. M-109R is equipped with indication of input terminal overload. Instrument is supplied from accumulator or power line adapter. Control is possible manually or remotely via serial interface RS232 Zelezna 3 | 619 00 Brno | Czech Republic | +420 543 250 886 | [email protected] | www.meatest.
