4. Safety instructions

4.1 Special notes on use

If the device is brought into the work-room from a cold environment
•
there is a risk that condensation might form on the electronics. In
measuring operations involving thermocouples pronounced changes in
temperature may cause substantial measuring errors. You are ad-
vised therefore to wait until the device has adjusted to the ambient
temperature before starting to use it.
Before using the mains adapter make sure that the mains voltage is
•
suitable.
Be sure to observe the maximum load capacity of the sensor power
•
supply.
Sensors with their own integrated power supply are not electrically isol-
•
ated from one another

4.2 Handling batteries / rechargeable batteries correctly

When inserting batteries / rechargeable batteries ensure that
these are correctly polarized.
If the device will probably not be needed for a relatively long
period of time or if the batteries are empty, remove the batteries;
this will prevent battery acid leaking onto the device and dam-
aging it.
Rechargeable batteries should be recharged as and when ne-
cessary.
You should never attempt to recharge an ordinary (non-re-
chargeable) battery; it may explode !
Batteries / rechargeable batteries must never be short-circuited
or thrown onto the fire.
Batteries / rechargeable batteries are special waste and must
not be discarded together with normal domestic waste.

ing sensors and peripherals because all parameters are stored in an EEPROM
located on the connector itself; repeat programming is thus no longer neces-
sary.
All sensors and output modules can be connected to all ALMEMO
instruments in the same way. Programming and functioning are identical for all
units. The following points apply to all devices in the ALMEMO
