3.10 Data Acquisition:
While in the RUN mode, the sensor is sampled every second. All values
except for STEL are updated and compared to the alarm settings. STEL is
updated and compared to it's alarm setting every minute.
3.11 Logging:
Each time the unit enters the run mode, a new session begins. The TWA,
STEL, and AVG levels all begin at zero. Each session's data is recorded
separately in memory and is printed with its own header and data summa-
ry.
In the RUN mode, the unit records data to memory in one minute intervals.
For each one minute interval the record contains the highest value (HI)
measured, the lowest value (LO) measured (oxygen), STEL (toxic), TWA
(toxic), and temperature. The summary data for each session will contain
the sensor type, serial number, last calibration date, alarm history, peak
level (PEAK), average level (AVG), minimum level (oxygen), peak STEL
(toxic), the session number, and the session start and stop times.
The unit logs data for approximately 60 hours. When the logging memory
is full, "FULL" appears in the display and the alarm will chirp. Press the
on/off key to acknowledge the memory full condition and stop the alarm's
chirp. The unit will continue to operate in a non-datalogging mode and will
measure gas, update values, and check for alarm conditions but it stops
logging time history data to memory.
4. PRINTING
The SafeLog 100 can send data serially to a computer or in parallel to a
printer. Serial data transmission requires the Quest cable #54-715 and par-
allel data transmission requires the Quest cable #56-875. With the cable
plugged into the unit, pressing the print key from the main menu results in
either "SEr" or "PrLL" showing in the display corresponding to which cable
is plugged in. If a cable is not plugged in, the unit will default to serial and
"SEr" will be displayed. Pressing the enter key initiates printing. "Prn"
shows up in the display while the unit is printing. Press and hold the enter
key during printing to abort.
4.1 Serial:
Use serial cable #54-715 to print data to, or communicate with, a personal
computer. Connect the cable between the SafeLog 100 and the PC's serial
RS-232 (com) port. QuestSuite™ for Windows software is recommended
for use with the SafeLog 100. "SEr" must be in the display for the unit to be
able to send and receive information from QuestSuite™. Other commu-
nication programs such as WIN 95's Hyperterminal may be used to capture
the unit's printout into a file.
Note:
The PC's serial port should be either a 25 pin male or a 9 pin male
connector. If the PC only has a 9 pin port available, then a standard
25 to 9 pin converter can be used. Do not use any other adapter
cables.
The serial format is:
Baud rate:
9600
Data bits:
8
Stop bits:
1
Parity:
none
Flow control:
Xon/Xoff
4.2 Parallel:
Use parallel cable #56-875 to send data to a parallel printer. Connect the
cable between the SafeLog 100 and the printer. Make sure the printer is
powered on and its ONLINE light (typically green) is lit.
