SURVEY MODE
Highlight
SURVEY MODE
in the
SAMPLE
menu and press
ENTER/START
to begin
immediate sampling in survey mode. In survey mode, after an initial four-second pause to purge
the flow system, the J605 will sample continuously. For complete information on survey mode,
see
on page
REGEN menu
The sensor saturation meter on the main screen (to the right of
s. sat
) indicates the current level of
saturation of the sensor with hydrogen sulfide.
When the sensor becomes saturated with hydrogen sulfide, as indicated by the sensor saturation
meter, a regeneration (regen) must be performed on the sensor to release the accumulated
hydrogen sulfide, before additional samples can be taken. See
for more information on the regeneration procedure.
The AC power supply/charger or the external battery pack must be plugged into the back of the
instrument before a regeneration can be performed.
The following options are available from the REGEN menu:
REGEN NOW
Connect external power to the instrument before performing a regeneration.
Highlighting
REGEN
NOW
and pressing
ENTER/START
will immediately start the sensor
regeneration process.
Do not disconnect external power during the regeneration.
WARMUP
To ensure maximum accuracy when sampling at levels less than 10 ppb, the J605 must be
warmed up with the Zero Air Filter in the intake, at the location to be sampled. To run the warm-
up, insert the Zero Air Filter in the intake, highlight
WARMUP
and press
ENTER/START
.
While warming up, the pump will run and the J605 will display a 5-minute countdown. When the
warm-up finishes, remove the Zero Air Filter and begin normal sampling. If the J605 is idle for
more than 20 minutes, another warm-up is required to maintain maximum accuracy at these low
levels.
