Maintenance:
The transmitter requires little maintenance. Occasionally the casing
can be wiped with dry cloth. Other maintenance required is bump
test, once in a month.
To keep the transmitter in good operating condition, perform the
following basic maintenance as required.
•
Calibrate, test & inspect the transmitter at regular intervals
and after exposure to high concentrations.
•
Keep an operations log of all maintenance, calibration & alarm
events.
•
Clean the exterior with a soft, damp cloth. Do not use solvents,
soap or polishes.
•
Do not immerse the transmitter in liquids.
Cleaning the Sensor:
The sensor is secured in SS adaptor with sinter or filter screen
(depending on gas). Clean the sinter/filter only with a dry brush
being careful not to clog the screen.
Clearing the Sensor:
The sensor has a high degree of resistance to common vapors &
gases. The sensor most likely clears itself after exposing the
sensor to the clean air and wait 10 to 30 minutes. Do not expose
a sensor to the fumes of inorganic solvents (such as paint fumes)
or organic solvents.
Caution Notes:
•
It is recommended that the calibration gas concentration for
toxic gas sensors be 50% of the selected measurement range.
•
For Oxygen, use pure air calibration gas.
•
NEVER allow the unit to be used in direct sunlight & rain.
•
NEVER expose the sensor to gas concentration higher than its
prescribed range.
