4.5.3.6 Exiting the Datalogging Adjust mode
When the PhD Ultra is properly configured, press
and hold the CAL button to save the changes. You
will be instructed to release the CAL button.
A screen will briefly announce that changes have
been made and the configuration updated. The
PhD Ultra will then shut itself down.
To exit from the datalogger configuration screens
without making or accepting any changes, press the
mode button at any time.
4.5.4 Downloading recorded data
PhD Ultra record keeping capabilities are most
useful when used together with Biosystems’ PC
Based “Datalink” Gas Detector Database Software.
Although downloading the recorded data to a
computer file offers the most complete way to
examine the data, it is not necessary to interface the
instrument with a computer in order to review the
data through the LCD or download directly to a
serial printer. Reviewing recorded data directly
through the instrument display screen allows the
user to answer two very important questions:
(1) Were my workers using their instruments?
(2) Did the atmosphere have any problems?
4.5.4.1 Viewing data
The Record Keeping Data Transfer mode is entered
by turning the PhD Ultra on while holding down the
"
-" key. The unit must be in the Technician mode
prior to being turned on to access record keeping.
Change modes if necessary as discussed in
Section 2.2.4.
The Record Keeping Data Transfer screen will be
shown followed briefly.
After a few seconds, the following screen will be
shown:
Press the + button to view data. The display will
briefly shows the following screen.
Press “+” to view the most recent monitoring
session. Press “-“ to view the oldest monitoring
session in the datalogger memory. After a few
seconds, the PhD Ultra will automatically show the
most recent monitoring session.
The numbers in this screen signify the session
number (1), the time the session was started and
completed, (14:46 - 14:52), and the date of the
monitoring session (May 20, 2004). If a location has
been entered, it will also be shown.
Use the "+" and "
-" keys to select the appropriate
session, then press the “CAL” button to view the
readings from session "1".
The instrument will automatically cycle between two
peak reading screens, one for oxygen, and one for
the other gases being measured. The oxygen peak
reading screen shows both the high (HI) and low
(LO) readings.
p
Following the peak readings screen for the LEL and
toxic sensors, the PhD Ultra will show the following
screen:
Press “CAL” to return to the list of monitoring
sessions.
Press the mode button at any time to exit the Data
Transfer / Record Keeping mode and turn the PhD
Ultra off.
4.5.5 Entering user ID and monitoring
location identification number
It is possible to assign alphanumeric identification
codes of up to 13 characters each to specify the
user or location name for the monitoring sessions.
This information is automatically added to all
downloaded records and reports for the session.
It is possible to enter up to 10 users and up to 15
locations in the instrument memory by using
Biosystems’ Datalink software to upload the lists
from a personal computer. It is also possible to
modify the current user name and monitoring
location directly through use of buttons on the
instrument keypad.
Once the lists are in the instrument memory it is
possible to “scroll” through the available choices and
either pick the appropriate name and location from
the list. New information may also be entered, but
