TS4000H
4.6 Selectable Options
The TS4000H contains a number of user configurable options that can be selected using the
supplied magnet.
Figure 15: Selectable Options
4.6.1 Sensor
Range
The Sensor Range is configured automatically by the TS4000H when a new electrochemical
cell is plugged into the Interface Module. The exceptions to this rule are specified below.
NOTE:
The sensor scale / type option is disabled when the Sensor Range is automatically
determined by the TS4000H.
The Sensor Range for the following five sensor types is not uniquely determined by the
TS4000H and must be configured manually:
Ammonia
(NH
3
)
Carbon monoxide (CO)
Chlorine
(Cl
2
)
Hydrogen
sulfide
(H
2
S)
Sulfur dioxide (SO
2
)
For these five types, the sensor range must be set from the base unit, after the sensor is
plugged into the interface module. When a Carbon Monoxide (CO) sensor cell is installed, the
selectable ranges are either 100 ppm or 500 ppm Full Scale (FS). When a Chlorine (Cl
2
)
sensor cell is installed, the user may select either 10 ppm or 20 ppm FS. When a Hydrogen
Sulfide (H
2
S) sensor cell is installed, the user may select either 20 ppm or 50 ppm FS. The 100
ppm Hydrogen Sulfide (H
2
S) uses a different sensor cell. When a Sulfur Dioxide (SO
2
) sensor
cell is installed, the user may select either 20 ppm or 100 ppm FS.
To Change the Sensor Range for CO, Cl
2
, H
2
S, NH
3
, and SO
2
1. Apply and hold the magnet on the GM logo on the Base Unit cover. Wait until “
SE
” displays
and then remove the magnet. This action places the unit into Setup Mode, causing “
Sr
”
menu to be displayed immediately.
2. Apply and remove the magnet and wait until “
CO
”, “
CL2
”, “
H2S
”, “NH3”, or
“SO2”
appears
on the display. The user will then have the following sensor ranges to choose from
(depending on the installed sensor):
“
CO
” –
100
and
500
“
CL2
“ –
10
and
20
“
H
2
S
“
– 20
and
50
“NH
3
” – 50 and 100
“
S02
“
– 20
and
100
