Note:
•
Where possible, we recommend that
installers use an accessible multi-
meter to verify the voltage reading.
When verifying the voltage reading
remember that the value measured
will equal the local 3 phase voltage /
1.732 (i.e. the square root of the 3-
phase system). For example, if you
have a 415V supply voltage, an
accurate voltage measurement at
the multi-meter will be between 239
and 240 volts (415 / 1.732 = 239.6).
EQ LTE™ data loggers correct this
measurement to reflect the actual 3
phase value!
Any voltage inconsistency is likely to be
associated with the earth bond. Be observant
of issues such as paint, dirt or other ingress
acting as a barrier between the BLACK volt
probe and the earth source!

Warning risk high pressure. Isolate
gas connection from the compressed
air system (e.g. gate or ball valve)
before attempting to locate the
pressure sensor. Read and
understand all safety instructions for
both EQ LTE™ data logger and the
compressed air installation and their
risks where the data logger will be
used before proceeding.
If in doubt stop immediately!
Locate the pressure sensor in such a way as
to avoid moisture or other forms of debris
forming on the sensor element.
Ideally, mount the pressure sensor upright!
Caution:
Ensure there is no compressed
air leakage around the pressure
sensors gas connection. Any
leakage can affect detected
pressure and give inaccurate
results.
Once the pressure sensor is located and pipe
