where:
A factor - factor A in the above equation
B factor - factor B in the above equation
min. Voltage - lower measuring range of gauge
max. Voltage - upper measuring range of gauge max.
Example: The User Deined gauge as below will behave identically to ITR90 gauge:
A factor = 0.725
B factor = 10.333
min. Voltage = 0.774V
max. Voltage = 10.0V
3.6.2 DEGASSING
Setup menu →Degassing
Degassing procedure can be activated for each channel (in case of active channels it available only
for ITR100 and ITR90 gauges). In addition, the user can set degassing time.
Due to increased power consumption during degassing, only one active or passive channel can be
degassed at a time.
Note
Set power for passive gauges before degassing. See point DEGASSING POWER
in chapter 3.6.1.2.
3.6.3 EMISSION CONTROL - EMISSION CONTROL MENU
Setup Menu →Emission Control
One of the advantages is automatic emission control, i.e. passive gauges emission or active gauges
emission, may be activated automatically. Emission may be controlled in the following modes:
1. Manual - controlled manually by the operator
2. Setpoint 1 - 10 - - emission is controlled by a selected pressure setpoint. Reaching the set-
point threshold activates emission in a given channel and lack of setpoint deactivates emis-
sion.
3. Digital inputs 1 - 4 - emission is controlled through the selected digital input.
Setting emission current is described in point EMISSION CURRENT in chapter 3.6.1.2
