The temperature sensor included in delivery is suitable for a temperature range
•
of -50 to +250 ºC. To utilise the full measurement range of the data logger, you
will need a temperature sensor with a more extensive measurement range
(available separately).
• Make sure only to use the temperature sensors specified to this effect for your
measurements (in this case: K type). Before connecting lines, check plugs or
sensor tips ("beads") for good condition and for flawless insulation (free of
damage).
• make sure that only the temperature sensors are exposed to the temperatures
to be measured. make sure to observe the safety provisions and the technical
data as regards the service temperature. The max. input quantities must never
be exceeded.
• Never try to press mixed-up connectors (+ and -) forcefully into the bushes.
This would destroy the bushes beyond repair, and they would have to be
replaced.
• Do not connect voltages! This might destroy the device.
• Hold the temperature sensor line end to/in the de-energized measuring fluid
(heat sink, etc., but not in caustic or inflammable fluids!).
