Section 6. Functional Tests and Calibration
6.1. Introduction
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.
CAUTION: Check local regulations on calibration or testing
requirements.
CAUTION:
The MGS contains sensitive electronic components
that can be easily damaged. Do not touch nor disturb any of these
components
NOTE:
The MGS is calibrated at the factory. After installation, a
zero adjustment maybe required due to differences in
environmental conditions.
IMPORTANT:
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.
IMPORTANT:
Murco recommends annual checks and gas
calibration. Murco also recommends sensor replacement every 3
years or as required. Calibration frequency may be extended
based on application, but should never exceed 2 years.
IMPORTANT:
In applications where life safety is critical,
calibration should be done quarterly (every 3 months) or on a
more frequent basis. Murco 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.
