With a wide resistance range from 1 M\u03a9 to 12 G\u03a9 and a maximum operating voltage of 5 kV DC, the M109R is ideal for use in calibration laboratories and service locations.<\/p>\n<h3>Accurate calibration of high resistors<\/h3>\n<p>The M109R uses four decades, allowing users to set resistance values within the range of 1 M\u03a9 to 12.221 G\u03a9. The circuits used are equipped with high-voltage relays that provide an insulation resistance of over 10\u00b9\u2075 \u03a9, while the special ERTALYTE insulation provides a surface resistance of over 10\u00b9\u2076 \u03a9. This prevents unwanted leakage currents and ensures extremely stable measurement results. This provides the instrument with exceptional accuracy and stability. The M109R is designed for both manual operation and external control via RS232, enabling integration into automated test setups.<\/p>\n<h3>Durable and flexible power supply<\/h3>\n<p>The unit is powered via a built-in rechargeable battery or a mains adapter (15V, 100-240V, 50\/60Hz), allowing for both stationary and mobile operation. A built-in overload indicator warns users of excessive input voltages, extending the safety and lifetime of the device.<\/p>\n<h3>Applications<\/h3>\n<p>The Meatest M109R is designed for applications in:<\/p>\n<p>&gt; Calibration of insulation meters and megaohmmeters<br \/>\n&gt; Testing of high resistances in laboratories and service environments<br \/>\n&gt; Verification and setting of high resistance meters<br \/>\n&gt; Research and development within high voltage technology<\/p>\n<p>The Meatest M109R High Resistance Decade Box provides precision and reliability for testing and calibrating high resistance instruments.
