Standard

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications not expressly approved by Sauermann could voice the user’s authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

1.  This device may not cause interference, and
2.  This device must accept any interference received, including interference that may cause undesired operation.

Operating instructions

Insert the batteries

• Remove the batteries compartment cover at the back of the device.
• Put the 4 alkaline AAA LR03 1.5V batteries supplied with the instrument.
• Carefully respect the polarity.
• Put back the battery compartment.

Perform a measurement

• Place the device in the required location to detect possible gas leak.
• Press ON/OFF key.
• The pre-heating phase of the sensor begins and lasts for 60 seconds. During this phase, all the visualisation leds of thresholds light one after the other. A few second before the end of the pre-heating phase, all the leds blinks at the same time.
• Place the probe as close as possible to the location of the suspected leak.
• Slowly move the probe (approximately 2 cm/second) in the direction to the possible source of the leak.

Manual and automatic autozero functioning
The detector performs an automatic autozero every 2 s to set its minimum threshold of detection. This autozero allows to guarantee an optimum gas detection whatever the conditions of use (contaminated environment, temperature variations,…). In case of detection, according to the amplitude of gas measurement, the automatic autozero will deactivate to guarantee a better location of the leak. It will automatically reactivate after a return to normal conditions. In case of high gas concentration with a wide contaminated area, the automatic autozero can be not enough to detect precisely the location of the leak, there will be a measurement saturation. In this case, it is possible to perform a manual autozero into the contaminated area to reset the detection and to get back to a progressive sensitivity when getting close to the leak source. To perform a manual autozero, please see next page.

Perform an autozero

• With the device turned on.
• Press at least 3 s the key to perform an autozero.
• The “Autozero” led turns on.

Setting of the sensitivity
If the gas concentration is high, press “Sens” key to set the sensitivity and like this to get a better identification of the leak source. Here are details about the three different sensitivities:

Activate/deactivate the audible signal

• By default, when starting the device, the audible signal is always active.
• With the device turned on.
• Press key to deactivate the audible signal.
• Press this same key to reactivate it.

 Maintenance

Change batteries

• With the device turned off.
• Remove the batteries compartment cover at the back of the device.
• Remove used batteries and insert new batteries (4 alkaline batteries AAA LR03 1.5 V) respecting the polarity.
• Put back the battery compartment.

Clean the instrument

• Clean the housing with a damp cloth (soap suds) if it gets dirty.
• Do not use aggressive cleaning agents or solvents.

Change the filter

• Unscrew the probe tip.
• Remove the filter located inside.
• Put a new filter.
• Screw the tip on the probe.
