6712FR Refrigerated Sampler
Section 4 Standard Programming
4-14
4.8.9 Adjust Volume Select this option to change the sample volume within the limits
of the currently programmed sample distribution. If you change
a sample volume, a volume changed event is logged.
4.8.10 Power Used 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.
4.9 Other Functions
In Standard Programming, the “Other Functions” menu screen
includes options for:
• Maintenance (see Section 7).
• Manual Functions (see below).
• Programming Style (see Section 3).
4.10 Manual Functions The manual functions programming screens let you:
• Take grab samples.
• Calibrate sample volumes.
• Operate the pump manually.
• Move the distributor arm.
4.11 Grab Samples 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.
