– BACHARACH MGS.150 SENSORS
To comply with the requirements of EN378 and the European F-GAS regulation, sensors must be
tested annually. However, local regulations may specify the nature and frequency of this test.
IMPORTANT: Failure to test or calibrate the unit in accordance with applicable
instructions and with industry guidelines may result in serious injury or death. The
manufacturer is not liable for any loss, injury, or damage arising from improper
testing, incorrect calibration, or inappropriate use of the unit.

Check local regulations on calibration or testing requirements

The MGS contains sensitive electronic components that can be easily damaged. Do not touch nor
disturb any of these components

If the MGS is exposed to a large leak it should be tested to ensure correct functionality by
electrically resetting the zero setting and carrying out a bump test. See procedures below.

Annual checks and gas calibration are recommended. It is also recommended that sensors are
replaced every 3 years or as required. Calibration frequency may be extended based on
application, but should never exceed 2 years.

The testing of the unit must be carried out by a suitably qualified technician, and must be done in
accordance with this manual and in compliance with locally applicable guidelines and regulations.

In applications where life safety is critical, calibration should be done quarterly (every 3 months)
or on a more frequent basis. Parasense is not responsible for setting safety practices and
policies. Safe work procedures including calibration policies are best determined by company
policy, industry standards, and local codes.

Before testing the sensors on-site, the MGS must have been powered up and allowed to stabilize.

Prior to carrying out a bump test, check and adjust the zero setting as described in the Calibration
section .
