User manual

- Make sure when handling the thermometer that the measuring media are absolute-

ly dead! The utmost caution is advised when dealing with voltages that exceed 25

V AC or 35 V DC. Even at these voltages you may get an electric shock that is dan-

gerous to life if you touch the electrical conductors.

- Make sure before each measuring that neither your measuring instrument nor your

temperature sensors are damaged.

- Make absolutely sure that the voltage between measuring instrument and earth

does not exceed 24 VACrms or 60 VDC.

- Do not use the measuring instrument under unfavourable ambient conditions or in

rooms that contain or may contain combustible gases, fumes or dusts. Make sure

for your own safety that neither the measuring instrument nor the measuring leads

get damp or wet. Avoid operation in the immediate vicinity of

a) strong magnetic fields (loudspeakers, magnets)

b) electromagnetic fields (transformers, motors, coils, relays, contactors, electro-

magnets, etc.)

c) electrostatic fields (charges / discharges)

d) transmitting antennas or HF generators

- Do not use the digital thermometer just before, during or shortly after a thunder-

storm (lightning stroke! / high-energy over-voltages!). Ensure that your hands,

shoes, clothes, the floor, the measuring instrument and the measuring leads, cir-

cuits and circuit elements are absolutely dry.

- If there is reason to believe that safe operation has become impossible, put the

device out of operation and secure it against unintended operation.

Safe operation must be presumed to be no longer possible if

- the device exhibits visible damages

- the device does not function any more

- the device was stored under unfavourable conditions for a long period of time or

- the device was exposed to extraordinary stress caused by transport.

- Never turn-on the measuring instrument immediately after it has been brought

from a cold into a warm room. Under unfavourable conditions, the condensation

water that forms may destroy your device. Leave the device turned-off until it has

reached room temperature.
