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.
