WARNING
The device may only be used in areas subject to explosion hazards which are
explicitly covered under the Ex Approvals which have been given to this device.
Electrical operating safety (Ex protection) is not guaranteed in an oxygen-
enriched atmosphere.
Remaining life of the device (only valid for Pac 3500)
– Once activated check the remaining life by pressing
[+]
while device is
turned off. The remaining time in days will be shown. After another press of
[+]
"d" will be shown.
After another press of
[+]
the gas to be measured will be shown, e. g. "750",
"d", "CO".
Activating a new device
– Press and hold
[+]
for approx. 3 seconds while "3, 2, 1" appears in the dis-
play. The device’s usable life is now started. The gas to be measured will
be shown. After 10 seconds the display will turn off or if

. The display counts down until startup: "3, 2, 1".
– The device 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" (only
valid for Pac 3500).
– The A1 and A2 alarm limits are displayed.
– If the calibration interval function is activated the days remaining until the
next calibration, e.g., » CAL « then » 20 « are displayed.
– If the bump test interval function is activated, the time until the bump test in-
terval elapses is displayed in days, e.g., » bt « then » 123 «.
– The first warmup time in seconds is displayed alternating with the letters
"SEC".
WARNING
Whenever the Pac 3500/5500 is opened, a bump test and/or a calibration
must be performed afterwards. This includes each battery replacement as
well as each sensor replacement in the Pac 3500/5500. Non-compliance
will mean that the proper functioning of the device cannot be guaranteed
which may impair the accuracy of the measurements.
WARNING
Before making safety-related measurements, check the adjustment and
adjust as needed, and check all alarm elements. If there are national regula-
tions, the bump test must be performed according to these regulations.
Faulty adjustment can lead to incorrect measurement results and, therefore,
also cause severe health risks.
Notice
All display segments are lit. Next, the LED, Alarm and Vibrating alarm are
activated in sequence. Check these before each use.
