The PUMP key

If the analyzer is equipped with an internal sample gas pump, this can be switched on and off
using the <PUMP> key. If the pump is switched off while the analyzer is in input mode, it is also
switched on again by pressing the <MEAS> key if parameterized accordingly
(see Configuration: 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 off via the binary
input. The binary input has priority over the key.
