Meriam M400-GI0300-02 Handheld Pressure and mA Calibrator/Data Logger Single Pressure Sensor

In continuous production for nearly 25 years, the MeriCal digital pressure transmitter calibrator is one of themost successful instruments to ever serve the process industries. Meriam’s NEW M4 Series Handheld Precision Calibrator / Data Logger builds on this reputation with an impressive array of new features, functions and improved accuracy specification.
 

The M400 includes one pressure sensor and one mA/V instrument. Chose from differential, gauge, compound or absolute pressure types and ranges from 10” H2O (pending) to 3000 PSIG full scale.

All M4 Series handhelds provide convenient electrical signal measurement and sourcing. Measure ±50V or ±100mA, source 24VDC, sink V, or source precise VDC or mA DC values using the supplied test leads. Accuracy is ±(0.015% of Reading + 0.002 units) over the entire operating temperature range. Source or sink values are easily entered using the Adaptive Interface Wheel and right arrow function key.

		Data Logging is standard on all M4 models. Select Data Logging from the Setup key menu and then enter the desired Interval and Duration parameters using the keypad controls. For M400 single pressure sensor units, pressure, VDC and mA DC values are saved to the SD card at each interval. M402 dual pressure sensor units log both pressure values plus VDC and mA DC values. The supplied SD card is located under the battery compartment cover. 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 M4 handhelds and SD card supports up to 100 different data log files.
		All DC voltage and current measurements are made using the same two 1/8” banana jacks located in the lower end of the handheld. This reduces the amount of time it takes to perform the measurement and potential errors. These jacks can provide temporary 24V DC power and measure loop current simultaneously. Sourcing DC volts and current is also a standard feature. Use the Sensor key to highlight the sensor desired and then use the Setup key to select the desired function. The Adaptive Interface Wheel is used to set precise values or configure step or ramp sourcing programs to test receiving devices.
