ofammablegas,vapors,orcombustibledust.
Operation in such an environment constitutes a
safety hazard. Prolonged use in a highly dense
corrosive gas (H
2
S, SO
X
, etc.) will cause a
malfunction.
• Do Not Remove the transmitter case
The case should be removed by YOKOGAWA’s
qualiedpersonnelonly.Openingthecaseis
dangerous, because some areas inside the
instrument have high voltages.
• Ground the Instrument before Making External
Connections
