Step Bump Testing Using Ga s Ampoule s

Remove the beaker from the sensor. Carefully remove any

ampoule remains from the gas detector and beaker.

6.5. Calibration Overview

To comply with t he requirements of EN378 and t he E uropean 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 c alibration or t esting

requirements.

6.6. Calibration Options

There are two available calibration options:

• Exchanging the sensor board for a new, pre-calibrated one and

send old one to B acharach for rec alibration (available for two-

alarm units and 1- and two-alarm IR units)

• On-site gas calibration.

These are explained in the next two sections.

6.7. Sensor Board Exchange

There are a number of advantages to sensor board exchange. It is

simpler and quicker than gas calibration.

NOT E: S ensor board exchange is available for t wo-alarm

semiconductor (SC) units and one- and two-alarm

infrared

(IR) units.

NOT E: Bacharach recommends exchangi ng your sensor

PCB for a new pre-calibrated one every 3 years.

Tools required:

• A pre-cali brated sensor board

• A voltmeter (crocodile clips recommended)
