5 Operation
5.1 Remaining life of the instrument
— Once activated check the remaining life by pressing
[+]
while
instrument is turned off. The remainig time in days will be shown.
After another press "d" will be shown.
After another press the gas to be measured will be shown,
e. g. "750", "d", "CO".
5.2 Activating a new instrument
— Press and hold
[+]
for approx. 3 seconds while "3, 2, 1" appears
in the display. The instrument’s usable life is now started. The
gas to be measured will be shown. After 10 seconds the display
will turn off or if
[+]
is pressed again, "d" will be shown. After
10 seconds the display will turn off or after another press the
remaining time in days will be shown. After 10 seconds the
display will turn off.
5.3 Turning the instrument on
— Press and hold
[OK]
. The display counts down until startup:
"3, 2, 1".
— All display segments are lit. Next, the LED, Alarm and Vibrating
alarm are activated in sequence. Please check these before
each use.
— The instrument will perform a self test.
— The software version and the gas name are displayed.
— The number of days of remaining operation are shown,
e. g. "750", "d".
— The A1 and A2 alarm limits are displayed.
—For the O
2
sensor: after the first activation of the instrument,
a sensor warm up time of up to approx. 15 minutes is needed.
The gas name flashes until the warm up time has passed.
5.4 Before entering a working place
— After turning the instrument on, the gas name to be measured
will normally be shown in the display.
— Check for the notice icon

— Clip the instrument to clothing before working in or near
potential gas hazards.
—
Insure that the gas opening is not covered and that the instrument
is also near to your breathing area.
5.5 Performing a “bump test” with gas
— Prepare a Dräger test gas cylinder with 0.5 l/min and a gas
concentration higher than the alarm threshold to be tested.
— Connect Dräger Pac 3000 and the test gas cylinder to the
calibration adapter or to the Dräger Bump Test Station.
— To enter the bump test mode press the
[+]
3 times within
3 seconds. The instrument beeps twice, quickly. The Display
begins to flash slowly.
— Open the regulator valve to let test gas flow over the sensor.
— If gas concentration exceeds the alarm thresholds A 1 or A 2 the
corresponding alarm will occur.
— To finish the bump test press
[OK]
, the
[!]
icon is removed from
the display and the instrument returns to the measuring mode.
— If during the bump test no alarm occurs within 1 minute, the
instrument alarm mode is entered to indicate failure. The error
icon
[X]
and the notice icon
[!]
are flashing; error code 240 is
shown upon acknowledgement.
"– – –"
is shown instead of the
gas name, and the
[X]
and
[!]
icon are lit. In this case the bump
test can be repeated or the instrument can be calibrated.
— The bump test can also be made by an automatic function. This
function can be activated using the PC software Pac Vision or
CC Vision (see section 5.8).
— If the bump test mode was entered by mistake, while the notice
icon
[!]
was not lit and no gas flow over the sensor, press
[+]
to
cancel the bump test mode and switch over to measurement
screen.
5.6 During operation
— If the allowable measurement range is exceeded or a negative
drift occurs, the following will appear in the display:
“”
(too high concentration) or
“”
(negative drift).
— Alarms are indicated as described in section 6.
— Continuous function of the instrument is indicated by the life
signal, which is a beep every 60 seconds, if configured
(see section 4).
5.7 Turning the instrument off
— Simultaneously hold both keys for approximately 2 seconds until
“3” appears in the display. Continue to hold both keys until the
countdown is finished. The alarm and LED will be activated
momentarily.
5.8 Calibration and configuration
— For calibration or individual configuration connect Dräger
Pac 3000 to a PC using the connecting cradle or the E-Cal
System. Calibration and configuration can be done with installed
software Pac Vision or CC Vision. A calibration “due date” can
be set using the operation timer (in days).
Strictly follow the instructions for use of the modules and software
in use.
