Description Specifications Literature Accessories Description The Meriam VMA0055 is a DC voltage and current measurement and simulation module for use with the Meriam MFT 4000 Series Multi-Function Tester. The module features the functionality of a DVM and loop calibrator for terrific versatility. When used with other MFT functions, the VMA / MFT combination provides valuable functionality not available in other devices.Measurement ranges include ±500 mV, ±55 V, and ±100 mA. Sourcing capabilities include 0-24 V and 0-22 mA. The VMA module will also simulate transmitter outputs when connected to a loop or it can be used to temporarily supply 24V DC loop power to unpowered devices during commissioning, outages or calibration activities.VMA0055 goes far beyond the ±50 volts / mA measurement capability of the MFT base unit and has its own isolated power supply so common ground problems are not an issue. MFT Users experience the following advantages:Power a transmitter directly from VMA:Use MFT 4000 and 4010 to calibrate transmitters anywhere, anytimeConcurrently use MFT base unit V / mA meter to simultaneously check transmitter outputUse MFT 4010 HART® communications to commission or reconfigure unpowered transmittersMeasure mV, V or mA as you would with a DVM:Reduce the number of tools the technician carriesResolution to 1/100,000 countsSelect desired V range for best possible accuracySource precise voltage or mA signals to check calibration or operation of receiving devices or step a positioner:Key in exact output value desiredIncrease or Decrease output value by predefined incrementsAuto-step tests are user defined for start and stop values, number of steps, dwell time, and manual or automatic advanceAvailable certifications include:CE MarkNIST traceable - standardIntrinsically Safe - MET Laboratories per CSA C22.2 and UL 913 Class I Division I, Groups A, B, C and D State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
