Relay Module - Dräger Polytron 7000 Instructions For Use Manual

1) To determine the overall power consumption of the gas detector in the case of use of the relay
or pump module, add up the individual power consumption values.
Ambient conditions during
operation
1) The readability of the display is impaired at temperatures below -20 °C (-5 °F) At negative tem-
peratures, the operability of the gas detector is affected be the increasing sluggishness of the
display.
