CAUTION:
For safety reasons, this equipment must be operated and
serviced by qualified personnel only. Read and understand the instruction
manual completely before operating or servicing.
CAUTION:
High off-scale readings may indicate explosive concentration.
CAUTION:
Any rapid up-scale reading followed by a declining or erratic
reading may indicate a gas concentration beyond the upper scale limit which
may be hazardous.
CAUTION:
Before each day’s usage, sensitivity must be tested on a known
concentration of pentane or methane equivalent to 25%-50% of full scale
concentration. Accuracy must be within -0% to +20% of actual
concentration. Accuracy may be corrected by referring to the zero/calibration
section of the instruction manual.
