Example
Calibration of an “acetone” detector using a calibration gas with 1% butane
Value to be displayed:
1% (injected butane) x 100 x 0.90 (butane/acetone coefficient) = 60% LEL
1.5% (butane LEL)
Note:
•
LELs vary according to the source.
•
Coefficients are accurate to ± 15%.
9.4 Maintaining the remote control
9.4.1 Replacing the batteries
The two AA batteries (1.5 V) in the device need to be replaced if transmission quality decreases.
In this case, remove the remote control (1) from its case (2), remove the cover from the battery
compartment (4) and replace the old batteries (3) with two new identical batteries. Replace the
cover (4), insert and tighten the screws, and put the remote control (1) back into its case (2).
