Peak Screen

The peak screen displays the highest (lowest for O

) concentrations

detected since the GX-2003 was turned on. Peak readings are stored in

the GX-2003’s memory until a higher level is detected, the peak

reading is reset, or the GX-2003 is turned off.

The lunch break feature enables the GX-2003 to remember peak

readings when it is turned off so it can continue them when it is

turned on again. See “Turning On the GX-2003, Normal Mode Only”

on page 14. To reset the peak readings during operation, press and

hold the RESET SILENCE button for a few seconds while in the peak

screen.

Elapsed Time Screen

The elapsed time screen displays the time in minutes since the GX-

2003 was last turned on. The elapsed time may be continued from the

last time the GX-2003 was in operation by using the lunch break

option. See “Turning On the GX-2003, Normal Mode Only” on

page 14.

TWA/STEL Screen

The TWA/STEL screen displays the time-weighted average (TWA)

and the short-term exposure limit (STEL) readings for CO and H

only.

The TWA reading is the average reading during the last 8 hours. If 8

hours have not elapsed since the last time the TWA reading was

cleared, the average is still calculated over 8 hours. The missing time

is assigned a 0 value (20.9% for oxygen) for readings.
