7.4.3.5 The PUMP key
If the analyzer is equipped with an internal sample gas pump, this can be switched on and o
using the <PUMP> key. If the pump is switched o while the analyzer is in input mode, it is also
switched on again by pressing the <MEAS> key if parameterized accordingly
(see Conguration: Inputs/outputs/pump: Pump at CAL/MEAS (Page 144)).
In addition to use of the <PUMP> key, the pump can also be switched on and o via the binary
input. The binary input has priority over the key.
