The Meriam M402 precision handheld electrical calibrator boasts an impressive array of features, functions and a terrific accuracy specification. The Meriam M402 provides convenient electrical signal measurement and sourcing while also providing two pressure sensors. Already a versatile instrument, the M402 includes a datalogging feature that enhances the unit's functionality of a wide range of applications.
The M402 measures DC voltage to ±50 V and DC current to ±100 mA. Additionally, users can source 24 VDC and measure mA, sink V or mA, or source precise VDC or mA DC values using the supplied test leads. The Meriam M402 calibrator features an accuracy of ±(0.015% of reading + 0.002 units) over the entire operating temperature range. The source or sink values are easily entered using the Adaptive Interface Wheel.
The Meriam M402 includes two pressure sensors available in gauge, compound or absolute pressure types and ranges from -15 to 3000 PSI. Pressure accuracy is up to ±0.025% of reading.
The Meriam M402 electrical calibrator has a single pressure sensor which is user-selectable. Datalogging is standard on the M402 and configured through the "setup" key menu. Pressure, V DC and mA DC values are saved to the SD card at each interval. Data can be moved to a host PC using the supplied USB cable and PC utility or by inserting the SD card in a compatible PC to copy the desired files. The M402 handhelds and SD card supports 100 data files.
