RKI Instruments Gas Tracer - Manual (Page 55)

Gas Tracer Operator’s Manual Display Mode • 47
Peak Screen
The Peak Screen displays the highest (lowest for O
2
) concentrations
detected since the Gas Tracer was turned on. Peak readings are stored
in the Gas Tracer’s memory until a higher level is detected, the peak
reading is reset, or the Gas Tracer is turned off.
The lunch break feature enables the Gas Tracer to remember peak
readings when it is turned off so it can continue them when it is
turned on again. See “Turning On the Gas Tracer, Normal Mode
Only” on page 20. To reset the peak readings during operation, press
and hold the RESET SILENCE button for a few seconds while in the
peak screen.
STEL Screen
The STEL Screen displays the short-term exposure limit (STEL)
readings for CO only. The STEL reading is the average reading during
the last 15 minutes.
