Indicating a temperature deviation

A temperature deviation is the diff erence between a predetermined
reference value and a measured temperature. The deviations are
shown as fi gures and by using coloured indicator on the display.
In addition, they will also be pointed out by an acoustic signal.

Setting reference values

♦
♦
Selection of the size of diff erence
On the appliance you can now set at which temperature dif-
ference (ΔT) the colour display and the acoustic signal should
respond.
♦
Lower temperature threshold = Reference temperature – ΔT
Upper temperature threshold = Reference temperature + ΔT

Aim the appliance as perpendicularly as possible to the
surface being measured.
Do not measure in dusty, smoky or steamy atmospheres.
Do not measure through transparent materials, such as glass
or plastics.
In the event of extreme temperature fl uctuations allow the
appliance to adjust to the ambient climatic conditions for
about 30 minutes before measuring.
