3.2.2.7 Display Modes
The receiver has a 2 line, 20 character per line LCD display with a character height of
0.19 in. (4.86 mm).
The display mode may be selected as either
AUTO
or
MANUAL
using the
CONFIGURATION
menu in the
SETUP
mode. If an alarm occurs with the display in
either mode, the display will change to the 4-channel summary mode automatically.
The difference between the
AUTO
and
MANUAL modes
is described below:
•
MANUAL
- Advance through the available channel display (
if more than one
channel
is
active
), including the 4-channel summary, by pressing the right or left
arrow
keys.
•
AUTO
- Automatically scrolls through the available channels, advancing to the next
channel every 3 seconds, but skips the 4-channel summery
Two types of data displays are possible in the
RUN
mode:
•
4-channel Summary
•
Single-channel Summary
When using the 4-channel summary display, each line is divided into two 10-character
groupings, one for each channel. This display mode is not available if the
AUTO
display
mode has been selected. Channel number, gas identification and instantaneous gas
concentration in ppm are displayed simultaneously as shown below:
1 CL
1.23 2 O3
45.6
3 CL
738 4 NH
0.12
The single-channel display mode shows the same data for the selected channel in addition
to the channel’s 10-character
TAGNAME
, short-term exposure limit and either time-weighted
average (TWA) or custom gas concentrations (depending on which has been selected).
A typical display is shown below:
CH1 TAGNAME 1.23
STEL: 4..56 TWA: 7.89
When in operation, the instrument selects the appropriate display mode using the following
guidelines:
Single-Channel Display
a. If only one
CHANNEL
is active (refer to section 4.3.3.2)
b. If
MANUAL
mode is selected to show a single
CHANNEL
c. During alarm if only one
CHANNEL
is active
4-Channel Summary
a. If all
CHANNELS
are
OFF
b. If
MANUAL
mode is selected to show the 4-
CHANNEL
summary
c. During alarm if more than one channel is active.
If desired, the
arrow keys
may be used to select the
single-channel display mode to show information for the
CHANNEL
in active alarm. If in single-channel mode, the
display reverts to the 4-channel summary mode if a
second alarm occurs.
