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, anytime
  • Concurrently use MFT base unit V / mA meter to simultaneously check transmitter output
  • Use MFT 4010 HART® communications to commission or reconfigure unpowered transmitters
Measure mV, V or mA as you would with a DVM:
  • Reduce the number of tools the technician carries
  • Resolution to 1/100,000 counts
  • Select desired V range for best possible accuracy
Source precise voltage or mA signals to check calibration or operation of receiving devices or step a positioner:
  • Key in exact output value desired
  • Increase or Decrease output value by predefined increments
  • Auto-step tests are user defined for start and stop values, number of steps, dwell time, and manual or automatic advance
Available certifications include:
  • CE Mark
  • NIST traceable - standard
  • Intrinsically Safe - MET Laboratories per CSA C22.2 and UL 913 Class I Division I, Groups A, B, C and D
