3.4.24 Analog Output Menu
Main Menu Communications Menu Analog Output Menu
The analog output can be set to be either Current or Voltage.
Different fields will be displayed depending on which analog
output type is selected.
The name of the gas for each analog output. All of the fields below
are repeated for each gas.
Sets the lower range limit (in concentration units). This is the value
at which the analog output should be at its minimum. For
example, 4mA for a 4 to 20mA current output.
Set the upper range limit (in concentration units). This value can
be edited but cannot exceed the Over Range value. This is the
value at which the analog output should be at its maximum. For
example, 20mA for a current output.
Set to Enabled or Disabled to turn the over-ranging feature on or
off.
This field is only visible when Over-Ranging is set to Enabled. Set
to the desired over range value. This value cannot be set below
the Max Range value. This is the alternate scale that is used for
the analog output when over-ranging is active and enabled. When
90% of the standard range is reached, this over range is
automatically entered. When 80% of the original range is reached,
it returns to the original range.
3.4.24.1 Analog Output Menu - Voltage
Main Menu Communications Menu Analog Output Menu
These items appear when Output Mode is set to Voltage.
Choices are 0V, 0.25V or 0.5V. This sets the voltage for a reading
of 0. Since the output cannot go negative, this offset can be used
to record negative readings.
Enables the user to calibrate the analog voltage output at a low
point. Increase/decrease the value until the connected equipment
reads 0.5V (refer to Section 3.4.24.1).
Enables the user to calibrate the analog voltage output at a full
scale point (5V). Increase/decrease the value until the connected
equipment reads 5V (refer to Section3.4.24.1).
