Description
As a new owner of EH4W you can
now wirelessly receive measurements
from anywhere on the jobsite and be
free from tangled wires. Your EH4W
can be set up to send you indoor
wet bulb measurements over-the-
air for real-time target superheat
calculations while you are outside at
the condenser taking actual superheat
readings.
Take measurements in multiple
places at once and have them sent
wirelessly to you anywhere you are
on the jobsite.
Your EH4W can wirelessly receive
measurements from any Fielpiece
transmitters and display the readings
wherever you are on the job.
C-Tick (N22675) EH4W also converts any Fieldpiece
accessor y head into a wireless
CE EN 61326-1 transmitter to send your measurement
over-the-air to a Fieldpiece wireless
FCC receiver like the HG3, LT17AW, or
EH4W. This allows you to set up your
WEEE accessory heads and monitor your
RoHS compliant measurements from anywhere on

first time. When powered on, EH4W
will automatically connect to the
last single-link receiver (LT17AW,
ET2W, or EH4W) or transmitter it was
sychronized to. No need to constantly
sync the same pair.
