Fluke Calibration KIT-EMM300 Instructions Manual page 5

mA/V dc Operation
The EMM provides measurement of V dc and mA with or without 24 V loop power.
To enable the mA/VDC function:
1. From the Controller Main screen, push EMM/HART on the left of the touchscreen.
2. Push mA/VDC to go into electrical measurement mode.
3. Choose the measurement mode as required. Push mA/DCV to toggle the mode between mA or V dc. In mA
measurement mode, push 24V Loop to enable/disable 24V loop power for a mA transmitter. DCV mode disables
24V loop power.
V dc Measurement
In V dc measurement mode, the Product measures the input dc voltage from 0 V to 30 V.
mA Measurement
In the mA measurement mode, the Product measures dc current from 4 mA to 20 mA.
See the Pressure Controller's Operators Manual for how to use the Programs Task with mA or V dc transmitters.
Pressure Transmitter Instructions
The Product tests, troubleshoots, and calibrates analog DUTs and smart pressure transmitters with HART
functionality. Pressure transmitters are usually classified as analog transmitters or smart transmitters.
Analog Transmitters
Analog transmitters let the user make two adjustments:
1. Zero the transmitter by adjusting the LRV (Lower Range Value) of the transmitter to the zero-pressure point that
supplies an output of 4 mA.
2. Adjust the URV (Upper Range Value) of the transmitter to the upper-working pressure that supplies an output of
20 mA.
These transmitters are usually adjusted with a screwdriver by turning two potentiometers on the top or the side of
the transmitter. The Product helps to calibrate these analog transmitters by providing an accurate, easy to control
source of pressure while also precisely measuring the analog 4-20 mA signal.
