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.

Set Span (4095)
20mA should be set up regardless of existing flow measurement.
Configure O/P2
The analogue current loop output (terminals 25 & 26), is set up from this mode. Press the ENTER key while this
display is shown to select it, then press the and keys to step through the available options. Press the
ENTER key to enter each option and change the displayed parameter.
Base of Output
An origin of 0 or 4mA can be set for the current loop output. The and keys will toggle between these two
options. Press the ENTER key to enter the new value.
5 CONFIGURE O/P2
Output = 4 to 20mA
Averaging Time of the Output
Any of the four averaging stacks (seconds, minutes, hours or days) may be used for the analogue output. They
are selected by the and keys and entered using the ENTER key.

Average 01m
Output Units
The analogue output can represent the gas concentration in units of either m/sec or m
3
/sec. The and keys
will toggle between these two options. Press the ENTER key to enter the new value.
