Channel 1 OFF Channel 1 is switched off (0 V).
Pressure p2 The inlet pressure p2 is output to Channel 1.
Pressure p1 The fore-vacuum pressure p1 is output to Channel 1 ).
LR mantissa The leakage rate mantissa is output linearly from 1...10 V (e.g. 5.4 x 10
-7
mbar l/s corresponds to 5.4V).
LR exponent The exponent is output as a step function: U = 1…10 V in steps from 0.5 V per decade beginning at 
1 V = 1x10
-12
(e.g. 5.4 x 10
-7
mbar l/s corresponds to 3.5 V).
LR linear The leakage rate mantissa is linearly output from 1 ... 10V. The upper limit (=10 V) is specified via the setting 
"Scaling
upper limit" (see below).
For example: 5.4 x 10
-7
mbar l/s and upper limit 1 x 10
-6
mbar l/s corresponds to 5.4V.
LR log. The output voltages are scaled logarithmically. The upper limit (=10 V) is specified via the setting "Scaling

upper limit". The increase is specified via "Scaling V/Decade".
For example: 10
-7
mbar l/s, upper limit 10
-6
mbar l/s and 2V/decade corresponds to an output voltage of 8V.

Control location** Local The T
ITANTEST™ is controlled with the buttons START, STOP and
ZERO.
Local and RS232 /
RS485
The T
ITANTEST™ is controlled both with the START / STOP and
ZERO buttons on the device and via the RS232 / RS485 inter-
face.
RS232 / RS485 The T
ITANTEST™ is controlled by an external computer via the
RS232 / RS485 interface. The START / STOP and ZERO buttons
on the device are deactivated.
All The T
ITANTEST™ is controlled both with the START/STOP and
ZERO buttons on the device and via the digital inputs and
RS232/RS485 interface.
PLC The T
ITANTEST™ is controlled via the digital input. The START/
STOP and ZERO buttons on the device are deactivated.
