RKI Instruments Gas Tracer 10,000 ppm - Manual (Page 38)

31 • Leak Testing 10,000 ppm Gas Tracer Operator’s Manual
NOTE: If the gas concentration exceeds the display range without
exceeding 9990 ppm, the full scale display range value will be
displayed but the actual gas reading at that time will be
recorded when you press and release POWER ENTER. For
example, if the display range is 1000 ppm but the gas level is
2300 ppm, the display will read 1000 ppm but the instrument
will save a reading of 2300 ppm.
If the gas concentration exceeds 9990 ppm in the Peak
Reading Screen, the instrument will go into an overscale
alarm and turn off the ppm sensor in order to protect it. The
full scale display range value will be displayed and OVER
will be recorded when you press POWER ENTER. The
instrument will then enter a 30 second warm up period in
order to turn the ppm sensor on again.
The unit will display SAVED along the bottom of the screen before
returning to the Station ID Select Screen.
To return to the Station ID Select Screen without taking a peak
reading, press and release the RESET SILENCE button.
