-
Calibration gas used = methane (CH4)
-
LEL of CH4 = 5%
-
Content used = 2.5% CH4 (50% LEL)
-
Therefore the value to be set and read on the voltmeter will be: U = 40 mV + 160 mV x
2.5/5 = 40 mV + 80 mV = 120 mV
In this specific case, once set, and with the gas, the 4 / 20 mA output will deliver 12 mA
(maintenance switch in "normal" position).
When the settings are complete:
• stop the gas injection
• remove the gas infeed pipe
• check that the signal returns to ZERO (40 mV on the voltmeter)
