Instruction 3015-4584 Rev 9
Tip:
If NO button is pressed within 60 seconds the monitor automatically continues
with the current TWA/twa.
Note:
During the time the monitor is OFF, the gas measurement is assumed to be
zero and will be factored into the TWA/twa calculation.
After selecting whether to start or continue a TWA/twa, the next screen shows the current elapsed
TWA/twa time.
Where: xx is the accumulated time used by the monitor in calculating the TWA/twa.
2.5 Peak Reading Operation
In addition to displaying the current halogen level, the monitor can also be set up to display its peak ppm
measurement. The peak reading display is selected by using the
2ndUNIT
function.
The display above shows that currently the monitor is detecting 100 ppm R31A and that a peak
measurement of 500 ppm has occurred.
The peak reading is reset by pressing the
ENTER
button.
2.6 Leak Detector Operation
The monitor can be configured to operate as a Leak Detector by setting the
AUDALRM
function (page
11) to
LEAK DETECTOR
.
When configured as a Leak Detector, the monitor will produce a leak detector type of audible feedback.
At zero ppm there will be a tic every 2 seconds with the tic rate increasing up to 20 tics/second when the
ppm level reaches the
ALRMLVL
setting.
2.7 Standby Mode
After becoming operational, the monitor can be placed into a Standby Mode. When taken out of standby
the monitor is ready for operation without waiting an additional 15 minutes to warm up. While in standby
the monitor will stop taking gas samples and stops purging itself from the purge-air bag.
Place the monitor into its Standby Mode by pressing both the
ENTER
and
ESC
buttons at the same time.
Take the monitor out of standby by again pressing both the
ENTER
and
ESC
buttons.
2.8 Battery – Charging and Using
2.8.1 Charging the Battery
The monitor is powered by a rechargeable battery pack located in a pouch on the side of the monitor’s
soft carrying case. The battery pack can be recharged at any time, regardless of the battery’s current
charge state.
The AC adapter provided accepts voltage inputs of 100 to 240 VAC. Plug the adapter into the wall, then
into the battery. Disconnect the adapter when the battery is fully charged. A fully charged battery pack
will power the monitor for approximately 8-12 hours.
