Basic technical data<strong>High</strong> <strong>Resistance</strong> <strong>Decade</strong> M-<strong>109R</strong><strong>Resistance</strong> range from 1 MOhm to 12,221 GOhmMaximum working voltage 5 kV DCAccuracy from 0,1% to 1%Temperature coefficient < 100 ppm / CVoltage coefficient < 1 ppm / V2,3 - wire connectionInternal accumulator / power line adapterInterface RS - 232o
Front panel ergonomy<strong>High</strong> resistance decade box is aimed for calibrating of insulation meters and megaohm-meters.It is suitable for calibration laboratories and service centres, where can be used also fortesting or setting of high resistance meters. <strong>High</strong> voltage relays with extremely high insulationresistance are used for switching of resistance components.M-<strong>109R</strong> is equipped with indication of input terminal overload. Instrument is supplied fromaccumulator or power line adapter.

<strong>High</strong> <strong>Resistance</strong> <strong>Decade</strong>!!! WARNING !!!Before using the resistance decade, follow these instructions:1. Check the quality of connection betwen terminals H, L.2. Check the pre-defined resistance value relative to the valueof applied voltage.3. When measuring and manipulating rotary buttons, workwith maximum caution-you are working with high voltage.4. Connect measuring voltage only for the necessary time.5. It is not allowable to leave the resistance decadeunsupervised when measuring voltage is connected.6. Before manipulation with measuring cables, checkswitching off of test voltage source.!!! If you are not absolutely sure aboutthe safety of the connection, do nottouch operating elementsor the instrument shield. !!!
