Before entering the workplace CAUTION Check and, if necessary, adjust the calibration before carrying out safety-relevant measurements. A bump test must be performed according to the national regulations. ●

Switch on the device. The current measured values are shown in the display. – Observe any warning » « or fault messages » «. The device can be operated normally. If the warning message does not disappear automatically during operation, the device must be serviced after the end of use. The device is not ready to measure and requires maintenance. WARNING The presence of catalyst poisons in the measured gas (e.g. volatile silicone, sulphur, heavy metal compounds or halogenated hydrocarbons) can damage the Cat Ex sensor. If the Cat Ex sensor cannot be calibrated to the target concentration anymore, the sensor must be replaced. The display of the Cat Ex sensor may be incorrect in an oxygen-poor atmosphere. Electrical operating safety (Ex protection) is not guaranteed in an oxygen-enriched atmosphere.

●

Check that the gas inlet opening on the device is not covered.

During operation – During operation, the measured values for every measured gas are displayed. – If a measuring range is exceeded or a negative drift occurs, the following displays are shown instead of the measured value display: » « (concentration too high) or » « (concentration too high at Ex channel) or » « (negative drift).

– Concentrations of combustible materials that are too high, may result in a lack of oxygen. – For O2 concentrations below 10 vol. % a fault is indicated for the Ex channel as » « instead of the measurement (only if measuring range ≤100 % LEL, not for >100 % LEL (heat conduction)). – In the event of an alarm, the corresponding displays, the visual, audible and vibration alarms are activated – see Chapter “Identifying Alarms”. After a measuring range has been exceeded, sensitivity to Ex gases may be increased temporarily.This sensor effect lasts for a maximum of 4 hours. Recalibration is not allowed during this time. After the measuring range of the TOX measuring channels has been exceeded temporarily (up to one hour), checking the measuring channels is not necessary. If using a Cat Ex sensor in Dräger X-am 5000, a fresh-air calibration may be required if the zero point has changed by more than 3 % LEL after an extreme impact load.
