The 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 ±1000 mV, 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.
 

Functions
Features
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
Read volts or mA
from MFT meter while
sourcing volts or
mA from VMA module
  • Test input isolation buffers with one MFT; apply mA value to buffer input with VMA and measure mA value output of buffer
  • Select mA or V measurement on MFT meter from the VMA output display without interruption of output
Simulate transmitter
output in externally powered loop
  • VMA modulates loop current to any selected value
  • Increase or Decrease simulated 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(-29°C)
I/P Device and
switch testing
  • Combined with a pressure module, perform I/P testing
  • Use VMA power source to wet switch contacts and use pressure and temperature modules for pressure and temperature switch testing
