The M7000/M8000 Series of advanced analog/digital multimeters from Megger use the latest microprocessor technology to provide the most comprehensive measuring ranges and features in a hand held instrument. There are four instruments in the range, the two M7000 models are for more general applications yet still incorporate many advanced features, whereas the M8000 models have been designed to provide greater accuracy with additional extensive measuring capabilities. The M7000 units offer rugged dependability for use in the most severe field conditions. Both the M7027 and M7029 are supplied in rugged yellow cases with wrap around rubberized holsters for added protection against mishandling. The main difference between the models is that the 7027 has a basic accuracy of 0.3% and the M7029 has a basic accuracy of 0.2%. Both models have dual displays and the choice of operation in the 4,000 count or the higher resolution 40,000 count mode. The M8000 models provide more advanced features for applications requiring more extensive measuring capabilities. The M8037 is the is the top-of-the-line instrument. It measures TRMS dc and ac which will allow more accurate measurements of various waveforms: sine, sawtooth, square, pulse trains, triangle, spikes, etc., as well as distorted waveforms with the presence of harmonics. The M8037 also features a backlight display for easier reading in poorly illuminated areas. Both the M8035 and M8037 have basic accuracies of 0.08%, dual displays and the choice of operation in the manual or autoranging mode. Capacitance, frequency, conductance and diode test facilities are included as standard features, plus for more advanced measurement applications the ability to record, store, sort and compare results is also provided.
