Place the in line-of-sightdevice
of the Wi-Fi signal.
No Wi-Fi signal or
erratic signal.
The device cannot
be powered on
with wireless remote
control.
When using the
scope at below zero
temperatures the
image quality is
worse than at
positive
temperatures.
Problem
The device is beyond reliable
Wi-Fi range.
There are obstacles between
the device and the signal
receiver (i.e. concrete walls).
Remote control is not
activated.
Low battery.
Activate the remote control
according to instructions.
Install a new CR2032 battery.
Because of variations in thermal conductivity, objects (surrounding
environment, background) under observation become warm more
quickly at above-zero temperatures, which allows higher
temperature contrast and, thus, the quality of the image produced
by a thermal imager will be better.
At low operating temperatures, objects under observation
(background) normally cool down to roughly identical
temperatures, which leads to lower temperature contrast, and to
image quality (precision) degradation. This is normal for thermal
imaging device.
Check
Corrective action
Rangefinder will not
measure distance.
There is an object in front of
the receiver or emitter lens
preventing signal
transmission.
Make sure that: the lenses are
not blocked by your hand or
fingers; the lenses are clean.
Inclement weather conditions (rain, mist, snow).
Large measurement
error.
The device is not being held
steadily when measuring.
Do not stress the device
when measuring.
Distance to the object
exceeds 1000 m.
Pick an object at a distance
longer than 1000m.
Pick an object with higher
reflection ratio (see point
”Peculiarities of operation”
in section 14.
Low reflection ratio (for
example, tree leaves).
