M400 Single Pressure Sensor, CE Mark
Handheld Pressure and mA Calibrator / Data Logger
MeriamåÕs NEW M4 Series Handheld Precision Calibrator / DataLogger builds on this reputation with an impressive array of new features,functions and improved accuracy specification! The M400 includes one pressuresensor and one mA/V instrument. Chose from differential, gauge, compound orabsolute pressure types and ranges from 10″ H2O (pending) to 3000 PSIGfull scale. Need two ranges for wider utility? No problem! All M4 Serieshandhelds provideconvenient electrical signal measurement and sourcing. Measure ±50V or ±100mA,source 24VDC, sink V, or source precise VDC or mA DC values using the suppliedtest leads. Accuracy is ±(0.015% of Reading + 0.002 units) over the entireoperating temperature range. Source or sink values are easily entered usingthe Adaptive Interface Wheel and right arrow function key. M4Series Data Sheet M4 Series Manual Temperature:Operating: -4 to 122°F (-20 to 50°C)Storage: -40 to 140°F (-40 to 60°C) Connections:Pressure: 1∕8″ NPT(female)Electrical: Standard banana jackson å?” centers Firmware updates, data retrieval: USB mini-B (female)
Power:Portable service: Four (4) AAalkaline batteries provides 30+ hours of continuous measurement serviceOperation with PC: Power over USBusing USB type A to mini-B cable (requires high power 500 mA port)Display:128 x 128 pixel (2″ x 2″viewable) monochrome display with backlightKeypad:Sealed membrane keypad with moldeddome switches and integrated Adaptive Interface WheelEnclosure:8.5″ L x 3.75″ W (max.)x 2.25″ D (max.), polycarbonate case, Softflexå¨ over-molded bumpers,IP40Weight:M400 single sensor: 1.5 åÐ 1.8lbs, M402 dual sensor: 1.8 lbsFirmware Features:Sensor Zero, Sensor Damping,Averaging (pending), Minimum/Maximum capture, Tare (pending), Units Select,Data Logging, Data Logging Record Indicator, Selectable Off Timer, SelectableBacklight Timer, Adjustable Contrast, Adjustable Backlight Brightness, BatteryMonitor Data Logging:Standard on all M4 models. SelectData Logging from the Setup key menu and then enter the desired Interval andDuration parameters using the keypad controls. For M400 single pressure sensorunits, pressure, VDC and mA DC values are saved to the SD card at eachinterval. M402 dual pressure sensor units log both pressure values plus VDCand mA DC values.
The supplied SD card is locatedunder the battery compartment cover. Data can be moved to a host PC using thesupplied USB cable and PC utility or by inserting the SD card in a compatiblePC to copy the desired files. The M4 handhelds and SD card supports 100 datafiles. DC voltage and CurrentMeasurement:Connections to transmitters ortransducers under test are made using the 1/8″ banana jacks located inthe lower end of the handheld. Alternatively, these jacks can providetemporary 24V DC power and measure loop current simultaneously. Sourcing DCvolts and current is also a standard feature. Use the Sensor key to highlightthe 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 stepor ramp sourcing programs (step and ramp are pending) to test receivingdevices.
Available Pressure Ranges:Specify ZM400 for Single Sensor orZM402 for Dual Sensors. NOTE: DN and DI excluded from ZM402. Examples:M400-DN0415 = M400 handheld,differential pressure sensor range 0 åÐ 415″ H2OM402-GI0030-GI1000 = M400handheld, dual gauge pressure sensors, 0 åÐ 30 and 0 åÐ 1000 PSIG
