ZENO

-3200 USER MANUAL

There are four Sensor Timing Loops. Each Sensor Timing Loop defines

how often the ZENO

-3200 takes a reading from the sensor (or sensors)

utilizing the Sensor Timing Loop during the Sample Duration.

The time defined for each of the four Sensor Timing Loops is in the Sensor Timing Loop Menu, which is

accessible from the Zeno Program Menu and will look something like this:

SENSOR TIMING LOOP MENU

(Cn/m) Change Item n To Value m (H) Help

(Z) Zeno Program Menu

Item 1: 0.5 (Timing Loop #1 Period)

Item 2: 1.0 (Timing Loop #2 Period)

Item 3: 1.5 (Timing Loop #3 Period)

Item 4: 2.0 (Timing Loop #4 Period)

As an example, configure the Sample Interval to be 20 seconds, the Sample Duration to be 19 seconds

and the Sensor Timing Loop period to be 2.5 seconds. The ZENO

-3200 would operate according to the

following timing diagram:

Sample Interval |---------------------------------------| 20s

Sample Duration |-------------------------------------| | 19s

Sensor Timing Loop ^ ^ ^ ^ ^ ^ ^ ^ 2.5s

Sensor Reading at each ^

Each sensor type requires a certain amount of time to collect data. From the above example, let's say that

the sensor requires up to 1 second to take a measurement. The addition of the time required by the sensor,

to the timing diagram, results in the following:

Sample Interval |---------------------------------------| 20s
