‘Leak’ will be blinking in the Ps1 mode field, waiting for either 

GO

 or 

CANC

 to be pressed.  (

Caution:

  

Do  NOT  press  GO  at  this  moment

).    Pressing 

GO

  will  activate  Ps1  Leak  mode  and  stop  ‘Leak’  from 

blinking.  Pressing 

CANC

 will revert back to Ps1 Measure mode.  For now, press 

CANC 

and return Ps1

Figure 3.28 : Ps1 Control mode 

 
‘Control’ will be blinking in the Ps1 mode field.  Also, ‘Control’ will be blinking in the Pt and Ps2 mode 
fields.  This is because when either Pt, Ps2 or Ps1 modes are changed to Control, all three modes (Pt, Ps2, 
Ps1) are automatically setup for Control.   (

Caution:

  

Do NOT press GO at this moment

).  Pressing 

GO

 

will activate all 3 outputs (Pt, Ps2, Ps1) into Control mode.  Pressing 

CANC

 will revert all 3 modes back 

to Measure.  For now, press 

CANC 

and return Pt, Ps2 and Ps1 to Measure mode. 

 

Note:  When Ps1 mode is changed to Control, Pt and Ps2 modes are automatically changed to Control.  
Similarly, when Pt or Ps2 mode is changed to Control, Ps1 mode is automatically changed to Control. 
 
Note:  Leak and Measure modes can be selected independently for Pt, Ps2 and Ps1. 

 

Ps2 Mode 

 
The Ps2 mode can be changed when the key# symbol
