Spectrum ON-LINE ENMET Corporation Introduction The SPECTRUM ON LINE is a small powered by an AC adapter operated single channel gas detection instrument. Depending on the sensor supplied with the instrument, it can detect one of a number of potential target gases. An electrochemical cell detects the gas, and the gas concentration is displayed on an LCD. Audio and visual alarms occur when the target gas concentration exceeds a preset alarm point.
ENMET Corporation Spectrum ON-LINE 1.2 Turn the instrument ON Turn the instrument ON, by plugging the power supply into a standard 110 VAC wall outlet. In uncontaminated air, for most instruments the display should read 0000 within ten seconds of turn-on. For an oxygen SPECTRUM ON LINE, the display reads near 20.9%. NOTE: Instruments using biased sensors, this time is extended to 4 minutes, stabilization may take as long as 1 hour. See Table 1. 1.2.

ENMET Corporation Spectrum ON-LINE 3.0 Operation 3.1 Operational Menu The operational menu diagram is shown in Figure 2. This menu is accessed with the OPTION pushbutton switch, the left hand switch as viewed from the front of the instrument. Successive displays are achieved by repeatedly pushing the switch; as indicated by “O” in the menu diagram.
Spectrum ON-LINE ENMET Corporation 3.2 Gas Concentration Display and Alarms The LCD furnishes a numerical display of the target gas concentration from 0000 to the upper limit of the range, shown in Table 1. The display of the target gas concentration is termed the "operational display". If the target gas concentration exceeds the upper limit of the range, the display is the numerical upper limit and a plus sign, for example,"0200+", for hydrogen sulfide.
ENMET Corporation Spectrum ON-LINE 4.0 Maintenance 4.1 Maintenance Menu From the operational display, press the OPTION pushbutton four times; "go SETUP" is displayed. This is the entrance to the maintenance menu. The maintenance menu flow diagram is shown in Figure 3. From Operational Display To Operational Display INVALID go SETUP S Key=0000 O S VALID run ZERO S Changes digit indicated by underscore cursor Locks underscored digit and moves cursor O AIR SET? S z30:0.
Spectrum ON-LINE ENMET Corporation 4.1.1 Key Entrance to the maintenance menu is guarded with a four digit numerical key. The factory default setting of the key is 1270(The process by which a different key is set is given in paragraph 4.1.5, below). When the valid numerical key is inserted, the user is allowed to enter the maintenance menu. When in the "go SETUP" location, press the SELECT pushbutton; "Key=0000" is displayed. The underscore cursor is under the left hand digit.
ENMET Corporation Spectrum ON-LINE 4.1.3 Calibration NOTE: Calibration must be performed at normal room temperature (20-25°C) for optimal performance. If the instrument is exposed to temperature extremes just prior to calibration, allow it to stabilize to room temperature. The internal temperature of the instrument is verified by cycling through the "see DATA" menu. In order to calibrate the instrument, it is first zeroed in a procedure similar to the one described above.
Spectrum ON-LINE ENMET Corporation 4.1.4 Changing the Alarm Level A valid key entry sets the instrument at the "run ZERO" location of the maintenance menu. Press the OPTION pushbutton twice to access the "set ALM" display, then press the SELECT pushbutton; ALM=0000" is displayed. This is called the alarm update window, and the value displayed is the present alarm setpoint. The underscore cursor is under the far left digit.
