2.4 Removing & Installing Rubber Boot

The data logger ships with an impact resistant rubber boot pre-installed.
OMEGA recommends leaving the protective rubber boot installed, but it can be
removed for convenience. When removing the rubber boot be sure to do so with
a support surface not more than 1 foot beneath the device to protect in the case of
an accidental drop.

To remove the device from the rubber boot first power off the device and
disconnect all external connections including power, analog & digital inputs,
and communication interfaces. Next while holding the device with one hand
gripping the top of the device, use the other hand to pry one of the bottom
corners of the rubber boot outward and downward until the corner of the device
pops free from the boot. Repeat for the other bottom corner of the device. With
both of the bottom corners free of the boot, continue to tilt the bottom of device
upward and pull it outward until it is free from the boot. Installation is the
reverse of removal.

2.6 Sensor Connections

This section shows how to connect sensors to your analog input terminals.
There are 8 or 16 analog input channels (depending on the model) each having
one positive terminal and one negative terminal clearly shown on the input
label. Depending on the type of sensor being connected 2 input channels may
be required. Input tables and figures are shown for each type of input. Bridged
based sensors (strain gages, load cells and mV output pressure transducers)
require excitation voltage which is provided on channels 1 and 2, 3 and 4,
9 and 10, 11 and 12 only. See tables 2-3 and 2-4 for wiring information.
