Set to one of the following ranges: 0 to 10, 0 to 20 or 4 to
20mA.
If required, the instrument can automatically transmit a
percentage of the full scale test signal: 0, 25, 50, 75, 100% of
the current output selected.
These set the sample time (see Section 4.3), i.e. the time the
monitor samples each stream. Different times can be entered
depending on whether the new stream is higher or lower than
the previous stream. This is determined by the values entered
on Programming Page 4.0. These parameters are normally
set to 12 and 15 minutes, but could be increased if required.
If fail-safe action is required select YES.
A differential set point can be set as a percentage of the set
point value. The differential setting operates on the set point.
Example - a 5% differential setting operates 2.5% above and
below the setpoint.
Set the differential required between 0 and 5% in 1%
increments.
Select YES or NO as required.
Set the required setpoint values within the instrument range.
Select the alarm action required - HIGH or LOW.
Select YES or NO as required.
Set the required setpoint values within the instrument range.
Select the alarm action required - HIGH or LOW.
Select YES or NO as required.
Set the required setpoint values within the instrument range.
Select the alarm action required - HIGH or LOW.
Note. Programming Pages 5.2 and 5.3 are displayed
on 4 and 6 channel versions only.
Enter the value of the previously entered security code.
Used for diagnostic purposes only.
