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. At relatively low concentrations of the gas, an alarm
can be acknowledged, which results in the temporary cessation of the audio alarm. Operation and maintenance
procedures are managed with two pushbutton switches. For ruggedness and EMF protection, the instrument enclosure
is an aluminum die casting. The instrument is shown in Figure 1.
A number of sensors have been qualified for target gases, the list is found in Table 1.
NOTE: All specifications stated in this manual may change without notice.

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. When the concentration of the target gas exceeds the alarm set point, the
audio and visual alarms are activated. The gas concentration continues to be displayed during alarm. The alarm point
is adjustable between a lower and upper alarm limit by accessing the maintenance menu; these and the factory setting
of the alarm point are also given in Table 1. A user should have a justifiable application-based reason for setting the
alarm point higher than the factory setting. When the target gas concentration drops below the alarm point, the audio
and visual alarms cease operation. The alarm point setting can be observed on the display by pushing the OPTION
pushbutton twice.
Some types of gases are difficult to detect in an ambient/static atmosphere. For these types of gases ENMET
recommends using a sampling system similar to ENMET Sample Draw Module 03700-029. See Appendix A Table 2.
For the oxygen S
(adjustable) and 23.5% (fixed).
If an alarm concentration is encountered when the display is at a location in the operational menu other than the
operational display, the audio and visual alarms are activated and the alarm cannot be acknowledged.
If the display is left idle at a location other than the operational display for 45 seconds it automatically transfers to the
operational display.
PECTRUM ON LINE, the zero gas display is 20.9% oxygen, and the two alarm points are at 19.5%
3.4 Alarm Acknowledge
When the instrument is in alarm, and the target gas concentration is below the upper alarm limit, the alarm can be
acknowledged by pressing and releasing the SELECT pushbutton, but only when the instrument is at the operational
display. The acknowledgement causes the temporary cessation of the audio alarm; the red LED continues to be ON.
The audio alarm is OFF for a period of four minutes, after which it is reactivated, if the gas concentration is still above
the alarm point. The alarm can again be acknowledged. However, acknowledgement of the alarm at gas
concentrations above the upper alarm limit does not result in audio alarm cessation, and if the gas concentration rises
above the upper alarm limit during an alarm condition which has been acknowledged, the audio alarm resumes
operation.
3.5 Data
The SPECTRUM ON LINE retains the maximum and minimum gas concentration values encountered since turn-on, or
since the data was cleared and reset. To access this press the OPTION pushbutton three times; "see DATA" is
displayed. Press the SELECT pushbutton; the maximum concentration since turn-on or last reset is displayed. Press
the OPTION pushbutton again; the minimum concentration since turn-on or last reset is displayed. Press the
OPTION pushbutton again; "clr DATA" is displayed. Pushing the SELECT pushbutton clears the data and resets it to
the current concentration. See comments on the use of this feature in Section 4.1.3, Calibration.
Pushing the OPTION pushbutton once more results in a display the internal temperature of the instrument in degrees
centigrade and Fahrenheit. Another push of the OPTION pushbutton results in a display of the version of the code
stored in the instrument. Push the OPTION pushbutton three more times to return to the operational display.
3.6 Interference Gases
For each target gas, some gases other than the target gas cause a sensor response, and thus are termed "interference
gases". A compilation of known interference gases for the various target gases is given in Appendix B, along with
gases that are known to not cause a sensor response.

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. To insert the key, press the OPTION pushbutton to change the left hand digit, and choose the
correct digit; then press the SELECT pushbutton, which locks in the chosen left hand digit and moves the underscore
cursor one space to the right. Continue this process until the four digit key is complete. When the valid key is inserted
in this manner, the display is transferred to the "run ZERO" portion of the maintenance menu. When an invalid key is
inserted, "INVALID" is briefly displayed, and the instrument returns to the operational display.
4.1.2 Zero
A valid key entry sets the instrument at the "run ZERO" location, of the maintenance menu, which enables the setting
of the zero gas concentration point. This is desirable if the zero reference of the gas sensor has drifted over a period of
time, indicated by a persistent gas concentration reading in a clean environment. Note that the calibration sequence
given below also includes setting the zero point. If a full calibration is required, instead of setting just the zero point,
push the OPTION button once; "run CAL" is displayed. See paragraph 4.1.3, below.
To set the zero point without performing full calibration, from the "run ZERO" location press the SELECT pushbutton;
"AIR SET?" is displayed. Be certain that the instrument is in clean air, uncontaminated by the target gas. If uncertain
of the environment, use pure compressed air from a pressurized cylinder, and flow it over the sensor at a low rate.
With the instrument in “AIR SET?”, press the SELECT pushbutton again. "z30:0.0v" is displayed; this is a counter
that counts down in seconds from 30 to 0. The validity of the new zero setting is then examined; if it is with in preset
parameters, the display is transferred to the operational display in the operation menu.
If the new zero setting is not between preset parameters, "C-FAULT" is displayed. Unplugging and then plugging in
the power supply turns the instrument OFF, then ON again. This re-boots the system with the most recent valid zero
setting.

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. Then the sensor
is presented with a known concentration of the target gas, in air or an inert gas such as nitrogen, called the "span gas".
After an appropriate interval, which is timed, the new span setting is examined for validity.
In some cases, the concentration of target gas in the span gas is greater than the concentration expected in the
workplace. If action is not taken, the calibration gas concentration may become the permanent maximum
concentration retained and displayed as data (see Section 3.5). It is good practice to record any data desired before
calibration, and then to reset after calibration to clear the calibration gas concentration form memory.
A valid key entry sets the instrument at the "run ZERO" location of the maintenance menu. Press the OPTION
pushbutton once to access the "run CAL" display, then press the SELECT pushbutton; "AIR SET?" is displayed. Zero
the instrument as described in paragraph 4.1.2 above. When the zero timer is complete, the display indicates
"GAS=XXXX", where the numbers indicate the correct span gas concentration the instrument is equipped to detect;
for a CO SPECTRUM the span gas is 100 ppm CO, for Cl2 SPECTRUM the span gas is 5 ppm chlorine, and so forth.
The correct span gas is given in Table 2 of Appendix A, for various target gases.
At the “GAS=XXXX” display:
1. Assure that the correct span gas is available.
2. Connect the calibration adapter to the cylinder along with the correct calibration cover; see Appendix A Table 2.
3. Open the calibration valve so that the span gas flows.
4. Press the SELECT pushbutton; "GAS SET?" is displayed.
5. Connect the span gas to the instrument so the calibration gas flows over the sensor.
6. Press the SELECT pushbutton; "XXX:Y.Yv" is displayed.
7. Remove span gas
The XXX is a counter which counts down in seconds to zero from the correct starting time to provide the proper time
interval for calibration; this time interval may vary depending on your target gas. The Y.Y v indicates a sensor signal
which is used during the sensor replacement procedure. When the timer reaches zero, the new calibration and zero gas
settings are examined for validity. If the value is with in preset parameters, the display is transferred to the gas
operational display in the operations menu.
During calibration the audio alarm is disabled, and after calibration is complete the audio alarm remains disabled for
up to 2.5 minutes.
If the new settings are not within preset parameters, "C-FAULT" is displayed. Unplugging and then plugging in the
power supply turns the instrument OFF, then ON again. This re-boots the system with the most recent valid zero and
calibration settings. Recalibrate. If after recalibration the instrument still displays “C-FAULT” the sensor may be
expired. Replace the sensor in accordance with Section 4.2.1.

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. Press the OPTION pushbutton to change the underscored digit; select the desired digit, and
press the SELECT pushbutton to lock in the desired digit and move the underscore cursor one position to the right.
When the desired new alarm point is set “new=XXXX” is displayed. Press either the OPTION or SELECT
pushbutton to exit the alarm update window. If the new alarm setting is valid, "exit" is displayed. Press the OPTION
pushbutton to return to the operational display, or the SELECT pushbutton to return to “run ZERO”.
For the safety of the user, there are upper and lower limits past which the alarm setting is invalid, and the instrument
does not accept them. If an invalid alarm setting is attempted, after the numerical value is inserted in the
"ALM=0000" window, pressing the OPTION or SELECT pushbutton results in a momentary display of "INVALID"
after which the display returns to the alarm update window. Exiting the alarm update window at this point results in an
alarm point setting unchanged from the value present when the procedure was begun.
Factory default alarm setpoints and alarm limits are shown in Table 1.
4.1.5 Setting a New Key
A valid key entry sets the instrument at the "run ZERO" location of the maintenance menu. Press the OPTION
pushbutton four times to access the "set KEY" display. Press the SELECT pushbutton once; "KEY=0000 is
displayed. A new key can be set by changing the underscored number with the OPTION pushbutton and moving the
underscore cursor with the SELECT pushbutton. After the new key is entered “new-XXXX” is displayed, press the
OPTION or SELECT pushbutton to display to “exit”, then press the OPTION pushbutton to return to “run ZERO”.
OTE: Four digit key numbers should be selected carefully and recorded. Without the correct key, the maintenance
N
menu cannot be accessed. If a four digit key number is lost, call ENMET customer service personnel.
4.2 Changing Components
Changing the sensor, or the display requires that the cover of the instrument to be removed; remove the four phillips
head, cover retaining, screws and then the cover.
4.2.1 Sensor Removal and Replacement
A sensor must be replaced when it no longer responds adequately to the target gas. This is indicated by a low gas
concentration reading when exposed to a known concentration of the target gas, and the inability to calibrate the instrument,
without a "C-FAULT" display after calibration. Expected sensor lifetimes in normal environments are given in Table 1.
After removing the cover of the enclosure, unplug the sensor from the circuit board.
AUTION: New sensors may come with a shorting clip that must be removed for proper operation.
C
Remove the shorting clip (if present) from the new sensor and plug the new sensor in place. Allow the sensor to
stabilize in the instrument with the power on for one hour before the initial calibration of a new sensor.
The initial calibration of a new sensor must be performed with the cover removed from the instrument enclosure.
Follow the procedure for calibrating the instrument as outlined in Section 4.1.3 of this manual with the following
modification:
N
OTE: During this procedure put the OPAQUE calibration cup, 02552-008, directly over the sensor and make sure it stays
centered.
During the application of the span gas, the counter counts down from an upper value given in Table 2. When
the counter gets down to 60, adjust the potentiometer located to the left of the display on the instrument circuit
board, so that the display to the right of the counter reads a little above the calibration voltage given for the
target gas in Table 2. As the counter continues, turn the pot so that the calibration voltage is reached when the
counter reaches 30. This is a one-time adjustment to align the sensor output with the instrument electronics. It
should only be performed upon sensor replacement. All future calibrations should follow the procedure in
Section 4.1.3.
Replace the cover of the instrument. Recalibrate the instrument according to the procedure in Section 4.1.3. to assure
sensor output alignment.
N
OTE: that the sensor must be replaced with a sensor for the same target gas; the instrument cannot be changed to detect
a different target gas without modifications in addition to changing the sensor type.

Returning an Instrument for Repair
ENMET instruments may be returned to the factory or any one of our Field Service Centers for
regular repair service or calibration. The ENMET Repair Department and Field Service Centers
also perform warranty service work.
When returning an instrument to the factory or service center for service, paperwork must be
included which contains the following information:
¾ A purchase order number or reference number.
¾ A contact name with return address, telephone and fax numbers
¾ Specific instructions regarding desired service or description
of the problems being encountered.
¾ Date of original purchase and copy of packing slip or invoice
for warranty consideration.
¾ If a price estimate is required, please note it accordingly and be
sure to include a fax number.
Providing the above information assists in the expedient repair and return of your unit.
Failure to provide this information can result in processing delays.
ENMET charges a one hour minimum billing for all approved repairs with additional time billed to
the closest tenth of an hour. All instruments sent to ENMET are subject to a minimum $30
evaluation fee, even if returned unrepaired. Unclaimed instruments that ENMET has received
without appropriate paperwork or attempts to advise repair costs that have been unanswered,
after a period of 60 days, may be disposed of or returned unrepaired COD with the evaluation fee.
Service centers may have different rates or terms. Be sure to contact them for this information.
Repaired instruments are returned by UPS/FedEx Ground and are not insured unless
otherwise specified. If expedited shipping methods or insurance is required, it must be
stated in your paperwork.
Note: Warranty of customer installed components.
If a component is purchased and installed in the field, and fails within the warranty term,
it can be returned to ENMET and will be replaced, free of charge, per ENMET’s returned
goods procedure.
If the entire instrument is returned to ENMET Corporation with the defective item
installed, the item will be replaced at no cost, but the instrument will be subject to labor
charges at half of the standard rate.
