A USB keyboard (AZI P/N: 990-0230) can be used to navigate the menu system and for data
entry for items such as Location Names. Connect the USB keyboard to one of the two USB Type
“A” ports on the back of the instrument. Either upper or lower case characters may be entered
when using a USB keyboard, while only upper case letters are available from the J605 keypad.
The keyboard arrow keys can be used to navigate the menu system.
SAMPLE menu
SAMPLE MODE
The Sample Mode setting provides the choice between auto-sampling and manual sampling. For
normal use, use manual sampling, which is the instrument default setting. If auto-sampling is
selected, the instrument will automatically sample at the interval set in
SET SAMPLE
INTERVAL
(below) without monitoring or attendance by the user.
Use the ▲and ▼arrows to
toggle between Manual and Auto, and use
ENTER/START
to save the selection. Use the
ESC
key to exit without saving changes. If auto-sampling is selected, the word Auto will appear below
the system date on the instrument’s main screen.
RANGE
Three different ranges and an Auto-ranging function are available in the J605. If the approximate
value of the expected H
2
S concentration is known, the instrument can be set into that specific
range prior to sampling (0, 1, or 2). If the expected H
2
S concentration is not known, Auto-
ranging can be used instead, and the J605 will test each sample in each range before displaying
the concentration. Using Auto-ranging results in longer test times, however accuracy is not
affected. The selected range also determines what units the J605 will use to display the results.
The three ranges and their default display units (ppb or ppm) are shown below:
RANGE CONCENTRATION
0
3 to 100 ppb
1
0.10 to 1.0 ppm
2
1.0 to 10.0 ppm
The range can be set or Auto-ranging can be toggled on or off by selecting Range from the
SAMPLE menu. Use ▲ and ▼ to scroll through the ranges 0, 1, 2 and Auto, and press
ENTER/START
to make a selection. Press
ESC
to exit without saving changes. The selected
range will be displayed on the main screen as a number (
0
,
1
,
2
) or as an
A
for Auto-ranging. See
for the location of the Range indicator.
SET SAMPLE INTERVAL
If auto-sampling is being used (as set in
SAMPLE MODE
above), the sample interval
determines how often the J605 will automatically take samples. Use
the ▲and ▼arrow keys to
scroll through the available sample intervals of 1, 2, 5, 10, 15, 30, 45, 60, 90 and 120 minutes, and
use
ENTER/START
to save the selected interval. Use the
ESC
key to exit without saving
changes.
The sample intervals refer to specific times on the instrument clock as measured in whole
multiples of the selected interval. For example, selecting a 10-minute sample interval will result
