The Meatest M109R is a high resistance decade box designed for the calibration and verification of insulation meters and megaohmmeters. With a wide resistance range from 1 MΩ to 12 GΩ and a maximum operating voltage of 5 kV DC, the M109R is ideal for use in calibration laboratories and service locations.
Accurate calibration of high resistors
The M109R uses four decades, allowing users to set resistance values within the range of 1 MΩ to 12.221 GΩ. The circuits used are equipped with high-voltage relays that provide an insulation resistance of over 10¹⁵ Ω, while the special ERTALYTE insulation provides a surface resistance of over 10¹⁶ Ω. 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.
Durable and flexible power supply
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.
