  • Page 98 TROUBLESHOOTING The following is a brief description of a few diagnostic displays: 1) Raw Sensor Readings The raw sensor readings provide a quick diagnosis on the response and the sensitivity of the sensor. When zero gas (fresh clean air) is applied to the monitor, the raw sensor readings typically should be between 100 and 300.
  • Page 99 TROUBLESHOOTING 5. Push the [Y/+] or [N/-] key to increase or decrease the threshold value “yyy” until it is about 10 - 15 counts above the “xxx” value. This will optimally set the lamp failure threshold. Press [MODE] key to exit this display. If the threshold value has changed, a message “Save?”...
  • Page 100 TROUBLESHOOTING 5) DAC Output Counts The menu allows the user to adjust the value of the analog output DAC use the [Y/+] and [N/-] keys. The remote alarm output signal on the serial interface cable is deselected and the analog output signal is selected in its place. This signal has a range of 0 to 2.5V in 4096 steps.
  • Page 101 [Y/+] key until this number just reaches 64. Then press the [Y/+] key two more times. With a Benzene RAE-SEP tube inserted, this number should be 46 to 52. For the VOC tube, this number should be 59 to 61.
