Assisted Diffusion Option - GMI V!SA Manual De Instrucciones

OPERATION
Fig. 2.17 Pump Symbol Displayed

2.7.2 Assisted Diffusion Option:

If assisted diffusion is the configured option, after
instrument warm-up, the pump remains ON at low speed.
This setting is used for reactive gases (*see note).
A press and hold of the green (RH) button re-sets the
pump to run at normal speed. When the pump is running at
normal speed, a pump symbol rotates in the display
as illustrated in Fig. 2.17. Press and hold the green (RH)
button again to switch the pump OFF. A further press
and hold of the green (RH) button re-sets the pump to
run at low speed.
* Note: GMI strongly recommend that pumped instruments,
configured with reactive gases, use assisted diffusion
mode in preference to diffusion mode.
Note: It is only possible to switch the pump ON / OFF
when instrument alarms are inactive.
