The Metravi M-3510A 6 1/2 Digits Bench-type Digital Multimeter offers compact size, light weight, fast measurement speed & throughput, expanded measurement functions, systematisation capability and highly usable interfaces, including a standard USB interface and an optional GPIB/RS-232 interface.
The device is suitable for both production and research/development use.

The Multimeter adopts the latest A/D technology and achieves 50,000 readings per second at 6 1/2 digits. When sending data to your computer, it can achieve high precision and stability compared to other DMMs with slow data transmission rate; your work efficiency will be greatly improved, and the operational cost will also be greatly reduced.

The Dual Measurement Display feature offers two measurement results displayed at the same time and it is easy to set up and configure. For example, when measuring DCV, you may also conduct Thermocouple measurement on the Metravi M-3510A. This allows you to observe temperature change while making other measurements. The Metravi M-3510A can function as a multimeter and a thermometer in one.

The Metravi M-3510A 6 1/2 Digits Bench-type Digital Multimeter supports RTD temperature measurement and standards such as ITS-90, IEC751 and Callendar-Van Dusen. The RTD function is recommended for more precise measurement. It also provides  Thermocouple (TC) function along with a built-in cold junction compensator for improved TC accuracy. Without additional plug-ins and reference temperature settings, you can measure temperature directly via Thermocouples of K, J, R, S, T, E, N, C and B types.

The meter offers the capacitance measurement and dual measurement display, in addition to standard measurements, such as DCV, DCI, ACV, ACI, 2WΩ, 4WΩ, Frequency, Period, Thermocouple & RTD, and the math functions, such as Limits, Ratio, MX+B, %, dBm, dB, Min/Max & Null. DC and AC Current Ranges go up to 10A.

The Metravi M-3510A adopts an analog conversion technique to provide true RMS value for ACV/ACI measurements regardless of the waveform shape. Only the “heating value” of the AC components of the input waveform is measured. For non-symmetrical waveforms, such as pulse trains, the DC components will be rejected by the RMS measurement.

Configuring the Metravi M3510A 6 1/2 Digits Bench-type Digital Multimeter is straightforward. Unlike other DMMs with complicated operation modes in the configuration menu, it offers easy-to-use SHIFT, CONFIG, ENTER buttons, arrow keys and corresponding soft keys at the lower part of the display across all the measurement configurations.

The Metravi Bearing Pulse Analyser BCA-111 combines the functions of a bearing pulse meter, a vibration meter, and a tachometer. It is used to check the operating condition of rotating machines, in order to detect mechanical faults and supply data for effective preventive maintenance.

With the BCA-111 maintenance personnel can monitor all significant aspects of mechanical machine conditions.

• the mechanical condition of rolling bearings  (bearing damage development).
• the lubrication condition of rolling bearing (lubricant film in the rolling interface).
• general machine condition (the effect of structural looseness, misalignment and out-of-balance on machine vibration).

The purpose of systematic condition monitoring is:

• to avoid unnecessary overhauls of machines in good working order.
• to avoid routine replacements of serviceable bearings.
• to improve the life expectancy of rolling bearings by optimising the lubrication.
• To detect trouble spots in time for planned repairs and replacements, avoiding both breakdowns and unnecessary production stops.

The condition monitoring functions of the Metravi BCA-111 is based on two widely used measuring techniques.

• Bearing Pulse Method for bearing monitoring.
