The following functions can be selected:
Off
The recorder output is switched off
P1 Pirani PHOENIX L300i
The inlet pressure P1 of the PHOENIX L300i will be shown logarithmic.
Fig. 17
P2 Pirani PHOENIX L300i
The fore vacuum pressure P2 of the PHOENIX L300i will be shown loga-
rithmic. Fig. 17
P1 (L200)
The setting for the inlet pressure P1 is identical with those of the L200, i.e.
1000 mbar comply 4V with 0.5V/decade logarithmic scale. Users can
exchange their L200 for a PHOENIX L300i without changing pin assign-
ment. Fig. 18
P2 (L200)
The setting for the fore vacuum pressure P2 is identical with those of the
L200,i.e. 1000 mbar comply 4V with 0.5V/decade logarithmic scale.
Users can exchange their L200 for a PHOENIX L300i without changing
pin assignment. Fig. 18
LR mantissa
The leak rate mantissa is recorded linearly from 1...10V. Fig. 20
LR exponent
The exponent is recorded as step function: U = 1...10V with steps of 0,5V
per decade, starting with 1V = 1·10
-12
mbarl/s. Fig. 19
LR linear
There will be two decades, the lower decade with voltages from 0.1 to
1.0V, the upper from 1.0 to 10.0V output. The scale is linear. The "Zoom
recorder output (leak rate) upper limit ( = 10V)" specified exponent deter-
mines the upper decade.
LR log
The fundamental output voltage is scaled logarithmic and can be freely
chosen. The voltage output ranges from 1 to 10 V with adjustable steps
of 0,5/1/2/2,5/5 to 10 V per decade (Fig. 21 shows the default setting)
