Setup
6. O
2
• Sensor ON/OFF (turns the sensor ON or OFF)
• Low Alarm
• High Alarm
7. CO Setup
• Sensor ON/OFF (turns the sensor ON or OFF)
• Low Alarm (sets the low CO alarm)
• High Alarm (sets the high CO alarm)
• STEL Alarm (if enabled) (sets the STEL CO alarm)
• TWA Alarm (if enabled) (sets the TWA CO alarm)
• Cal Gas (sets the expected CO calibration gas)
8. H S Setup
2
• Sensor ON/OFF (sets H
• Low Alarm (sets the low H
• High Alarm (sets the high H
• STEL Alarm (if enabled) (sets the STEL H
• TWA Alarm (if enabled) (sets the TWA H
• Cal Gas (sets the expected H
9. VOC Setup
• Sensor ON/OFF (sets VOC sensor ON or OFF)
• Low Alarm (sets the low VOC alarm)
• High Alarm (sets the high VOC alarm)
• STEL Alarm (if enabled) (sets the STEL VOC alarm)
• TWA Alarm (if enabled) (sets the TWA VOC alarm)
• VOC Auto-range (if enabled) (sets the display to read in 100 ppb increments
when below 10 ppm)
Select ON for PPB:
• This mode allows for improved signal stability at low concentrations and
can be used to determine if the low level VOC concentration is increasing
or decreasing. Response times are longer (see 8. Performance Specifi-
cations, Table 14).
NOTE:
In VOC Auto-range, the response time will increase by approximately 10 seconds.
Failure to wait the appropriate time can result in an incorrect reading.
• Display will read in increments of 100 ppb from 0 to 9900 ppb (9.9 ppm);
(100 ppb = 0.1 ppm); then, it switches to ppm readings at readings >10 ppm.
NOTE:
After set-up, the instrument will display:
"Warning - 100 ppb increments - see manual".
