PROGRAMMING STYLE

The 6712FR has a “fuel gauge” that gives an indication of power usage. The controller keeps track of how much power has been consumed since the last time it lost power. If the controller is powered by an external battery, this fuel gauge can help you estimate the condition of the battery.

Keep in mind that the sampler has no idea as to how much charge was originally stored in the battery (or even if a battery is being used), and therefore has no idea as to the remaining capacity of its power source.

In Standard Programming, the “Other Functions” menu screen includes options for:

Maintenance (see Section 7).

4.11Grab Samples

The manual functions programming screens let you:

Take grab samples.

Calibrate sample volumes.

Operate the pump manually.

Move the distributor arm.

Grab samples let you take a single sample on demand, collecting the sample in an external container (Figure 4-4). Keep in mind:

When the sampler delivers a grab sample, it runs through a com- plete sampling cycle, using the current settings for volume and for line rinses or retries. If it is a two-part program, the sampler uses the settings for part A.

To take a grab sample while the sampler is running a program, you must interrupt the program by pressing the Stop key. Restart the program by running it again.

To take a grab sample:

1.Disconnect the pump tube from the bulkhead fitting.

2.Place the end of the tube over a collection container.

3.Follow the steps in Taking a Grab Sample at left.

4.Reconnect the pump tube to the bulkhead fitting.
