7.2.3
Type of Gas Correction PENNINGVAC (GAS
PM
)
The PENNINGVAC gauge heads are normally calibrated for measurements in nitrogen or
air. With the aid of the parameter GAS
PM
you can set up the measurement channel to other
types of gas.
For this proceed as follows:
Select the parameter GAS
PM
.
Press the pushbutton PARA.
o
The setup characteristic is displayed.
Use the arrow pushbuttons so as to change the characteristic.
o
The value of the parameter is changed.
You can set up the correction factor for a gauge head in the range of 0.2
– 1.0 – 8.0. The
setting of 1.0 supplies the uncorrected measured value.
7.2.4
Sensor Switch-on Type (S-on)
This parameter defines how the PENNINGVAC gauge head is switched on.
You can set the switch-on time to the following values:
HAnd
Manual. The gauge head can be switched on by pressing the pushbutton UP (
Chapter
6.4.3.3 Switching the PENNINGVAC on, page 29).
ECt
Externally through optocoupler (PLC compatible high-level > 13 VDC; 7 mA at 24 VDC).
Hot
Warm start. The sensor is switched on automatically upon switching on the instrument. After
a power failure the measurement is started automatically.
CH 1
Through measurement channel TM1. With the aid of the next parameter t-on you can define
a switch-on value. When the pressure in the measurement channel TM1 drops below the
switch-on value, the sensor is switched on.
CH 2
Through measurement channel TM2. With the aid of the next parameter t-on you can define
a switch-on value. When the pressure in the measurement channel TM2 drops below the
switch-on value, the sensor is switched on.
7.2.5
Sensor Switch-on Value ( t-on)
This parameter will only appear when the sensor switch-on time has been set to CH 1 or
CH 2 (
Chapter 7.2.4 Sensor Switch-on Type (S-on), page 36).
Through the parameter t-on you can define a switch-on value. When the pressure in the
respective measurement channel drops below the switch-on value, the gauge head is
switched on.
