The On trigger setting requires a trigger to be set up.<br />
Pressing the Change Enable button opens the Equation<br />
Builder to set up the trigger conditions. Once this has<br />
been entered, the trigger is displayed in the “Enable<br />
sampler when:” box.<br />
Latch sampler enable - If this box is unchecked, the inhibit<br />
line will continue to toggle between enabled and disabled as the<br />
conditions change. When this box is checked, the inhibit line will<br />
keep the sampler enabled once triggered, even if the condition no<br />
longer exists. This state will not change until the Reset Latch<br />
button is pressed.<br />
Disable plotter when not sampling - When this box is<br />
checked, the instrument’s plotter will only run when the sampler<br />
is enabled.<br />
Block access to front panel - When this box is checked, front<br />
panel sampler enable changes are not possible and the flow<br />
meter displays a message stating that the access has been<br />
blocked.<br />
Sampler Pacing<br />
Flow Pulse<br />
Control the sampler pacing by choosing one of the pacing options.<br />
• No sampler pacing - The flow logger or flow meter will<br />
not send flow pulses.<br />
• Flow paced - paces the sampler at a rate proportional to<br />
the flow rate by using volume intervals. Use the Change<br />
Pacing button to set the interval.<br />
• Trigger paced - paces the sampler at a time interval that<br />
can change according to a triggered condition.<br />
To set up trigger paced sampling:<br />
1. Select the Trigger paced radio button. The Time paced<br />
interval box becomes active.<br />
2. Enter the When trigger is true interval in minutes. This<br />
is the pacing interval while the trigger condition is met.<br />
3. Enter the When trigger is false interval in minutes. This<br />
is the pacing interval while the trigger condition has not<br />
been met.<br />
4. Set the trigger by pressing the Change Pacing button.<br />
Build the trigger in the Equation Builder.<br />
5. Press the Apply button.<br />
Use this window to set the flow pulse interval. A flow pulse is a<br />
50 millisecond pulse used to pace a sampler. Enter a value within<br />
the minimum and maximum range listed.<br />
It is important that this setting and the sampler’s pulses<br />
between sampling events setting work together to produce the<br />
desired volume interval. For example, if the flow meter sends a<br />
flow pulse every 100 gallons, and the sampler takes a sample<br />
every 10 flow pulses, the actual volume between samples is 1000<br />
gallons.<br />
