7.9.4.4. Output Span
Select the required span using the

and

keys for each digit. The ENTER key is pressed to enter the value of
each digit. The units will be displayed in either m/sec or m
3
/sec, depending on what has been selected
beforehand. The current value will be displayed for 1 second when this option is entered. The display then
defaults to zero; thus the span value must be re-entered for the unit to function correctly.

Span 020.0m/sec
7.9.4.5. Set mA Output
Should a fault condition occur, the current output of the instrument may be set to any of the following options.

Set the output at 0 mA
–
ZERO .

Adjust the output to the measured concentration even though a fault condition exists
–
MEAS .

Hold the last measurement
–
HOLD .

Set the output to full scale (20mA)
–
F . S .
5 CONFIGURE O/P2
Fault cond ZERO
One of these options can be selected by pressing the ARROW keys, when the desired option is displayed press
the
ENTER key.
6.9.3.6. Set mA Output
This is set at the factory and should not be altered without due consideration.
From this option the current levels of the analogue output are set up. Press the
ENTER key to select it, and the
operator is prompted to set the current levels at 0 and 20mA.
5 CONFIGURE O/P2
Set Zero (0000)
When this is displayed the current output should be set to 0mA as measured with a calibrated current meter
across the analogue current loop terminals. Nothing else should be connected to these terminals when the
output is being set up. The value is adjusted using the two arrow keys; the

arrow will take the current output
up and the

arrow will take it down. Press the ENTER key when the correct output current is displayed on the
ammeter.
Zero milliamps should be set up; no matter what has been selected as the base of the current
output .
In a similar manner as above the current output level should now be set to 20mA.
5 CONFIGURE O/P2
Set Span (4095)
20mA should be set up regardless of existing flow measurement.
7.9.5. Alarm Hi
The operation of the volt-free contact alarm output (terminals 12, 13 & 14), is configured from this mode.
