Description
3. VOC The VOC method of sampling is a manual means of triggering a sample/log.
Once configured for VOC, the RUN mode prompts you to type a tag* identifier.
After you enter the tag, the instrument stands ready until you press either the
LOG key on the basic probe or the ENTER key on the instrument. Once
LOG is initiated, the instrument counts down. Samples are taken over that
count down and the highest reading achieved, or average (or last) reading is
logged in memory and displayed on both displays. The stored values are cleared
by pressing either the LOG key on the basic probe or the ENTER key on the
instrument. Each VOC log must be done manually and individually.
4. F.E. The F.E. method of sampling is a manual means of triggering a sample/log
using a pre-configured monitor route file which has been downloaded and
stored in instrument memory. The F.E. method requires use of the optional
enhanced FE probe. You choose a sample time of between 2 and 20 seconds
and you choose to log either the highest reading or average (or last) reading
achieved during the sample time. Once configured for F.E. and the RUN mode
entered, the FE probe menu screen guides you through the monitor route, displaying
each pre-configured tag identifier in sequential order. A SEARCH
function is available at the probe menu to allow you to find tags that are out of
order. The probe display prompts you to confirm the tag* identifier, after
which the instrument stands ready until you either select LOG from the probe
or press the ENTER key on the instrument. Once initiated, the instrument
begins a count down, sampling over the configured sample time. The reading
sampled during the countdown is displayed on both displays and your are
given the option to save the reading in memory or to select LOG again. The
stored values are cleared by selecting LOG on the probe display or by pressing
ENTER on the instrument. Each F.E. log must be done individually and manually.
*Tags may be entered manually or via a reader.
The RUN mode displays (as governed by the LOG selection) are:
NONE
AUTO, VOC, or F.E.
PID: 80.00 ppm
