6.6.4.2 Define recorder output
• Main Menu > Settings > Interfaces > Define Define recorder output r
The signals to be recorded can be selected in this submenu. With the left
keys the pin can be selected, with the right keys a function is assigned to
the selected pin.
The following signals can be selected:
OFF The recorder output is switched off.
P1 (L200)
The setting for the inlet pressure is identical with those of the L200. Users
can exchange their L200 for a Phoenix without changing pin assignement.
P1 (Pirani)
The inlet pressure P1of the PhoeniX will be shown logarithmic
P2 (L200)
The setting for the forevacuum pressure is identical with those of the
L200. Users can exchange their L200 for a Phoenix without changing pin
assignement.
P2 (Pirani)
The forevacuum pressure P2 of the PhoeniX will be shown logarithmic.
LR lin The fundamental output voltage is scaled linear. The fundamental voltage
is 0-10 V in scalable steps from 0.5 to 10 volts per decade.
For information about scaling see chapter 6.6.4.6 .
LR log The fundamental output voltage is scaled logarithmic. The voltage output
ranges from 1 to 10 V with adjustable steps of 0.5 V to 10 V per decade.
For adjusting of scaling see chapter 6.6.4.6 .
leak rate LR mantissa
The leak rate mantissa is recorded linearly from 1 … 10 V.
leak rate (exponent) The exponent is recorded as step function: U = 1 … 10 V with steps of
0.5 V per decade, starting with 1 V = 1×10

Softkey 7: Local
The PhoeniX is controlled via the START, STOP and ZERO buttons at the
control panel or remote control.
